Single Ended Active Clamp/Reset PWM
FEATURES
DESCRIPTION
Provides Auxiliary Switch Activation
Complementary to Main Power
Switch Drive
The UCC3580 family of PWM controllers is designed to implement a variety
of active clamp/reset and synchronous rectifier switching converter topolo-
gies. While containing all the necessary functions for fixed frequency, high
performance pulse width modulation, the additional feature of this design is
the inclusion of an auxiliary switch driver which complements the main
power switch, and with a programmable deadtime or delay between each
transition. The active clamp/reset technique allows operation of single
ended converters beyond 50% duty cycle while reducing voltage stresses
on the switches, and allows a greater flux swing for the power transformer.
This approach also allows a reduction in switching losses by recovering en-
ergy stored in parasitic elements such as leakage inductance and switch
capacitance.

as follows:
Delay 1= 1.1pF ·R3
Delay2 is designed to be larger than Delay1 by a ratio
shown in Figure 2.
RAMP: A resistor (R4) from RAMP to the input voltage
and a capacitor (CR) from RAMP to GND programs the
feedforward ramp signal. RAMP is discharged to GND
when CLK is high and allowed to charge when CLK is
low. RAMP is the line feedforward sawtooth signal for the
PWM comparator. Assuming the input voltage is much
greater than 3.3V, the ramp is very linear. A flux
comparator compares the ramp signal to 3.3V to limit the
maximum allowable volt-second product:
EAIN: Inverting input to the error amplifier. The
noninverting input of the error amplifier is internally set to
2.5V. EAIN is used for feedback and loop compensation.
EAOUT: Output of the error amplifier and input to the
PWM comparator. Loop compensation components
connect from EAOUT to EAIN.
GND: Signal Ground.
LINE: Hysteretic comparator input. Thresholds are 5.0V
and 4.5V. Used to sense input line voltage and turn off
OUT1 when the line is low.
Volt-Second Product Clamp = 3.3 • R4 • CR.
REF: Precision 5.0V reference pin. REF can supply up to
5mA to external circuits. REF is off until VDD exceeds 9V
(–1 and –3 versions) or activates the 15V clamp (–2 and
–4 versions) and turns off again when VDD droops below
8.5V. Bypass REF to GND with a 1mF capacitor.
OSC1 & OSC2: Oscillator programming pins. A resistor
connects each pin to a timing capacitor. The resistor
connected to OSC1 sets maximum on time. The resistor
connected to OSC2 controls guaranteed off time. The
combined total sets frequency with the timing capacitor.
Frequency and maximum duty cycle are approximately
given by:
SHTDWN: Comparator input to stop the chip. The
threshold is 0.5V. When the chip is stopped, OUT1 is low
and OUT2 continues to oscillate with guaranteed off time
equal to two non-overlap delay times. OUT2 continues to
switch after SHTDWN is asserted until the voltage on
VDD falls below VCS (typically 4 V) in order to discharge
the clamp capacitor.

UVLO and Startup
this clamp must be activated as an indication of reaching
the UVLO on threshold. The internal reference (REF) is
brought up when the UVLO on threshold is crossed. The
startup logic ensures that LINE and REF are above and
SHTDWN is below their respective thresholds before
outputs are asserted. LINE input is useful for monitoring
actual input voltage and shutting off the IC if it falls be-
low a programmed value. A resistive divider should be
used to connect the input voltage to the LINE input. This
feature can protect the power supply from excessive
currents at low line voltages.
For self biased off-line applications, -2 and -4 versions
(UVLO on and off thresholds of 15V and 8.5V typical)
are recommended. For all other applications, -1 and -3
versions provide the lower on threshold of 9V. The IC re-
quires a low startup current of only 160mA when VDD is
under the UVLO threshold, enabling use of a large trickle
charge resistor (with corresponding low power dissipa-
tion) from the input voltage. VDD has an internal clamp
at 15V which can sink up to 10mA. Measures should be
taken not to exceed this current. For -2 and -4 versions,

APPLICATION INFORMATION (cont.)
The soft start pin provides an effective means to start
the IC in a controlled manner. An internal current of
20 A begins charging a capacitor connected to SS once
the startup conditions listed above have been met. The
voltage on SS effectively controls maximum duty cycle
on OUT1 during the charging period. OUT2 is also con-
trolled during this period (see Figure 1). Negation of any
of the startup conditions causes SS to be immediately
discharged. Internal circuitry ensures full discharge of
SS (to 0.3V) before allowing charging to begin again,
provided all the startup conditions are again met.

Voltage Feedforward and Volt-Second Clamp
UCC3580 has a provision for input voltage feedforward.
As shown in Figure 3, the ramp slope is made propor-
tional to input line voltage by converting it into a charging
current for CR. This provides a first order cancellation of
the effects of line voltage changes on converter perfor-
mance. The maximum volt-second clamp is provided to
protect against transient saturation of the transformer
core. It terminates the OUT1 pulse when the RAMP volt-
age exceeds 3.3V. If the feedforward feature is not used,
the ramp can be generated by tying R4 to REF. How-
ever, the linearity of ramp suffers and in this case the
maximum volt-second clamp is no longer available.

APPLICATION INFORMATION (cont.)
Output Configurations
a single pin is used to program the delays between
OUT1 and OUT2 on both sets of edges. Figure 1 shows
the relationships between the outputs. Figure 2 gives the
ratio between the two delays. During the transition from
main to auxiliary switch, the delay is not very critical for
ZVS turn-on. For the first half of OUT1 off-time, the body
diode of the auxiliary switch conducts and OUT2 can be
turned on any time. The transition from auxiliary to main
switch is more critical. Energy stored in the parasitic in-
ductance(s) at the end of the OUT2 pulse is used to dis-
charge the parasitic capacitance across the main switch
during the delay time. The delay (Delay 1) should be op-
timally programmed at 1/4 the resonant period deter-
mined by parasitic capacitance and the resonant
inductor (transformer leakage and/or magnetizing induc-
tances, depending on the topology). However, depend-
ing on other circuit parasitics, the resonant behavior can
change, and in some cases, ZVS turn-on may not be ob-
tainable. It can be shown that the optimum delay time is
independent of operating conditions for a specific circuit
and should be determined specifically for each circuit.
The UCC3580 family of ICs is designed to provide con-
trol functions for single ended active clamp circuits. For
different implementations of the active clamp approach,
different drive waveforms for the two switches (main and
auxiliary) are required. The -3 and -4 versions of the IC
supply complementary non-overlapping waveforms
(OUT1 and OUT2) with programmable delay which can
be used to drive the main and auxiliary switches. Most
active clamp configurations will require one of these out-
puts to be transformer coupled to drive a floating switch
(e.g. Figure 5). The -1 and -2 versions have the phase of
OUT2 inverted to give overlapping waveforms. This con-
figuration is suitable for capacity coupled driving of a
ground referenced p-channel auxiliary switch with the
OUT2 drive while OUT1 is directly driving an n-channel
main switch (e.g. Figure 4).
The programmable delay can be judiciously used to get
zero voltage turn-on of both the main and auxiliary
switches in the active clamp circuits. For the UCC3580,

(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)

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.
