SNVS325D –JANUARY 2005–REVISED APRIL 2013  
APPLICATIONS INFORMATION  
The LM2852 is a DC-DC synchronous buck regulator belonging to Texas Instrument’s SIMPLE SWITCHER  
family. Integration of the PWM controller, power switches and compensation network greatly reduces the  
component count required to implement a switching power supply. A typical application requires only four  
components: an input capacitor, a soft-start capacitor, an output filter capacitor and an output filter inductor.  
INPUT CAPACITOR (CIN)  
Fast switching of large currents in the buck converter places a heavy demand on the voltage source supplying  
PVIN. The input capacitor, CIN, supplies extra charge when the switcher needs to draw a burst of current from  
the supply. The RMS current rating and the voltage rating of the CIN capacitor are therefore important in the  
selection of CIN. The RMS current specification can be approximated by:  
IRMS = ILOAD  
D(1-D)  
where  
•
D is the duty cycle, VOUT/VIN. CIN also provides filtering of the supply.  
(1)  
Trace resistance and inductance degrade the benefits of the input capacitor, so CIN should be placed very close  
to PVIN in the layout. A 22 µF or 47 µF ceramic capacitor is typically sufficient for CIN. In parallel with the large  
input capacitance a smaller capacitor may be added such as a 1µF ceramic for higher frequency filtering.  
SOFT-START CAPACITOR (CSS)  
The DAC that sets the reference voltage of the error amp sources a current through a resistor to set the  
reference voltage. The reference voltage is one half of the output voltage of the switcher due to the 200kΩ  
divider connected to the SNS pin. Upon start-up, the output voltage of the switcher tracks the reference voltage  
with a two to one ratio as the DAC current charges the capacitance connected to the reference voltage node.  
Internal capacitance of 20pF is permanently attached to the reference voltage node which is also connected to  
the soft-start pin, SS. Adding a soft-start capacitor externally increases the time it takes for the output voltage to  
reach its final level.  
The charging time required for the reference voltage can be estimated using the RC time constant of the DAC  
resistor and the capacitance connected to the SS pin. Three RC time constant periods are needed for the  
reference voltage to reach 95% of its final value. The actual start-up time will vary with differences in the DAC  
resistance and higher-order effects.  
If little or no soft-start capacitance is connected, then the start-up time may be determined by the time required  
for the current limit current to charge the output filter capacitance. The capacitor charging equation I = C ΔV/Δt  
can be used to estimate the start-up time in this case. For example, a part with a 3V output, a 100 µF output  
capacitance and a 3A current limit threshold would require a time of 100 µs:  
DV  
I
3V  
3A  
Dt = C  
= 100 mF  
= 100 ms  
(2)  
Since it is undesirable for the power supply to start up in current limit, a soft-start capacitor must be chosen to  
force the LM2852 to start up in a more controlled fashion based on the charging of the soft-start capacitance. In  
this example, suppose a 3 ms start time is desired. Three time constants are required for charging the soft-start  
capacitor to 95% of the final reference voltage. So in this case RC=1ms. The DAC resistor, R, is 400 kΩ so C  
can be calculated to be 2.5nF. A 2.7nF ceramic capacitor can be chosen to yield approximately a 3ms start-up  
time.  
SOFT-START CAPACITOR (CSS) AND FAULT CONDITIONS  
Various fault conditions such as short circuit and UVLO of the LM2852 activate internal circuitry designed to  
control the voltage on the soft-start capacitor. For example, during a short circuit current limit event, the output  
voltage typically falls to a low voltage. During this time, the soft-start voltage is forced to track the output so that  
once the short is removed, the LM2852 can restart gracefully from whatever voltage the output reached during  
the short circuit event. The range of soft-start capacitors is therefore restricted to values 1nF to 50nF.

COMPENSATION  
The LM2852 provides a highly integrated solution to power supply design. The compensation of the LM2852,  
which is type-three, is included on-chip. The benefit to integrated compensation is straightforward, simple power  
supply design. Since the output filter capacitor and inductor values impact the compensation of the control loop,  
the range of L, C and CESR values is restricted in order to ensure stability.  
OUTPUT FILTER VALUES  
Table 1 details the recommended inductor and capacitor ranges for the LM2852 that are suggested for various  
typical output voltages. Values slightly different than those recommended may be used, however the phase  
margin of the power supply may be degraded.

CHOOSING AN INDUCTANCE VALUE  
The current ripple present in the output filter inductor is determined by the input voltage, output voltage, switching  
frequency and inductance according to the following equation:  
D x (VIN - VOUT  
)
DIL =  
f x L  
where  
•
•
•
•
•
•
ΔIL is the peak-to-peak current ripple.  
D is the duty cycle VOUT/VIN.  
VIN is the input voltage applied to the PVIN pin.  
VOUT is the output voltage of the switcher.  
f is the switching frequency.  
L is the inductance of the output filter inductor.  
(3)  
Knowing the current ripple is important for inductor selection since the peak current through the inductor is the  
load current plus one half the ripple current. Care must be taken to ensure the peak inductor current does not  
reach a level high enough to trip the current limit circuitry of the LM2852.  
As an example, consider a 5V to 1.2V conversion and a 500kHz switching frequency. According to Table 1, a  
15µH inductor may be used. Calculating the expected peak-to-peak ripple,  
1.2V  
(5V - 1.2V)  
x
5V  
500 kHz x 15 mH  
DIL =  
= 121.6 mA  
(4)  
The maximum inductor current for a 2A load would therefore be 2A plus 60.8 mA, 2.0608A. As shown in the  
ripple equation, the current ripple is inversely proportional to inductance.  
OUTPUT FILTER INDUCTORS  
Once the inductance value is chosen, the key parameter for selecting the output filter inductor is its saturation  
current (Isat) specification. Typically Isat is given by the manufacturer as the current at which the inductance of the  
coil falls to a certain percentage of the nominal inductance. The Isat of an inductor used in an application should  
be greater than the maximum expected inductor current to avoid saturation. Below is a table of inductors that  
may be suitable in LM2852 applications.

SPLIT-RAIL OPERATION  
The LM2852 can be powered using two separate voltages for AVIN and PVIN. AVIN is the supply for the control  
logic; PVIN is the supply for the power FETs. The output filter components need to be chosen based on the  
value of PVIN. For PVIN levels lower than 3.3V, use output filter component values recommended for 3.3V. PVIN  
must always be equal to or less than AVIN.  
PVIN = 3.3V  
AVIN = 5V

SWITCH NODE PROTECTION  
The LM2852 includes protection circuitry that monitors the voltage on the switch pin. Under certain conditions,  
switching is disabled in order to protect the switching devices. One result of the protection circuitry may be  
observed when power to the LM2852 is applied with no or light load on the output. The output regulates to the  
rated voltage, but no switching may be observed. As soon as the output is loaded, the LM2852 begins normal  
switching operation.  
LAYOUT HINTS  
These are several guidelines to follow while designing the PCB layout for an LM2852 application.  
1. The input bulk capacitor, CIN, should be placed very close to the PVIN pin to keep the resistance as low as  
possible between the capacitor and the pin. High current levels will be present in this connection.

2. All ground connections must be tied together. Use a broad ground plane, for example a completely filled  
back plane, to establish the lowest resistance possible between all ground connections.  
3. The sense pin connection should be made as close to the load as possible so that the voltage at the load is  
the expected regulated value. The sense line should not run too close to nodes with high EMI (such as the  
switch node) to minimize interference.  
4. The switch node connections should be low resistance to reduce power losses. Low resistance means the  
trace between the switch pin and the inductor should be wide. However, the area of the switch node should  
not be too large since EMI increases with greater area. So connect the inductor to the switch pin with a short,  
but wide trace. Other high current connections in the application such as PVIN and VOUT assume the same  
trade off between low resistance and EMI.  
5. Allow area under the chip to solder the entire exposed die attach pad to ground for improved thermal and  
electrical performance.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability  
information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that  
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between  
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight  
in homogeneous material)  
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.  
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.  
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation  
of the previous line and the two combined represent the entire Device Marking for that device.

IMPORTANT NOTICE  
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other  
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest  
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and  
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale  
supplied at the time of order acknowledgment.  
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms  
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary  
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily  
performed.  
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and  
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide  
adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or  
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information  
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or  
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the  
third party, or a license from TI under the patents or other intellectual property of TI.  
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration  
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered  
documentation. Information of third parties may be subject to additional restrictions.  
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service  
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.  
TI is not responsible or liable for any such statements.  
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements  
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support  
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which  
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause  
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use  
of any TI components in safety-critical applications.  
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to  
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and  
requirements. Nonetheless, such components are subject to these terms.  
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties  
have executed a special agreement specifically governing such use.  
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in  
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components  
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and  
regulatory requirements in connection with such use.  
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of  
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
