Buck DC-DC Converter IC  
The TB7101AF is a single-chip buck DC-DC converter IC. The  
TB7101AF contains high-speed and low-on-resistance power  
MOSFETs for the main switch and synchronous rectifier to  
achieve high efficiency.  
Features  
Enables up to 1 A of load current (I ) with a minimum of  
OUT  
Weight: 0.017 g (typ.)  
external components.  
Fixed output voltage: V  
= 1.2 V/1.5 V/1.8 V/2.5 V/3.3 V (typ.)  
OUT  
A high 1-MHz oscillation frequency (typ.) allows the use of small external components.  
Uses only an inductor and two capacitors to achieve high efficiency.  
Allows the use of a small surface-mount ceramic capacitor as an output filter capacitor.  
Enable threshold voltage : V  
= 1.5 V, V = 0.5 V(@V = 5 V)  
IL(EN) IN

This product has a MOS structure and is sensitive to electrostatic discharge. Handle with care.  
The product(s) in this document (“Product”) contain functions intended to protect the Product from temporary  
small overloads such as minor short-term overcurrent, or overheating. The protective functions do not necessarily  
protect Product under all circumstances. When incorporating Product into your system, please design the system (1)  
to avoid such overloads upon the Product, and (2) to shut down or otherwise relieve the Product of such overload  
conditions immediately upon occurrence. For details, please refer to the notes appearing below in this document and  
other documents referenced in this document.

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the  
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly  
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute  
maximum ratings and the operating ranges.  
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook  
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test  
report and estimated failure rate, etc)

Application Notes  
Inductor Selection  
The inductance required for inductor L can be calculated as follows:  
V

: Input voltage (V)  
: Output voltage (V)  
: Oscillation frequency = 1 MHz (typ.)  
: Inductor ripple current (A)

*: Generally, ΔIL should be set to approximately 30% of the maximum output current. Since the maximum output  
current of the TB7101AF is 1 A, ΔIL should be 0.3 A or so. Therefore, the inductor should have a current rating  
greater than the peak output current of 1.15 A. If the inductor current rating is exceeded, the inductor becomes  
saturated, leading to an unstable DC-DC converter operation.  
When TB7101AF (T5L3.3, F) and V = 5 V, the required inductance can be calculated as follows. Be sure to  
IN  
select an appropriate inductor, taking the VIN range into account.

Output Capacitor Selection  
Use a ceramic capacitor as the output filter capacitor. Since a ceramic capacitor is generally sensitive to  
temperature, choose one with excellent temperature characteristics (such as the JIS B characteristic). As a rule  
of thumb, its capacitance should be 10 μF or greater for TB7101AF (T5L3.3, F), TB7101AF (T5L2.5, F),  
TB7101AF (T5L1.8, F), and 20 μF or greater for TB7101AF (T5L1.5, F), TB7101AF (T5L1.2, F). The capacitance  
should be set to an optimal value that meets the system's ripple voltage requirement and transient load response  
characteristics. Since the ceramic capacitor has a very low ESR value, it helps reduce the output ripple voltage;  
however, because the ceramic capacitor provides less phase margin, it should be thoroughly evaluated.  
Component Values (@VIN = 5 V, Ta = 25°C)

Undervoltage Lockout (UVLO)  
The TB7101AF has undervoltage lockout (UVLO) protection circuitry. The TB7101AF does not provide output  
voltage (V ) until the input voltage has reached V (2.5 V typ.). UVLO has hysteresis of 0.1 V (typ.). After  
OUT  
UVR  
the switch turns on, if V drops below V  
(2.4 V typ.), UVLO shuts off the switch at V  
.

Thermal Shutdown (TSD)  
The TB7101AF provides thermal shutdown. When the junction temperature continues to rise and reaches T  
SD  
(160°C typ.), the TB7101AF goes into thermal shutdown and shuts off the power supply. TSD has a hysteresis of  
about 20°C. The device is enabled again when the junction temperature has dropped by approximately 20°C from  
the TSD trip point. The device resumes the power supply when the soft-start circuit is used upon recovery from  
the TSD state.  
Thermal shutdown is intended to protect the device against abnormal system conditions. It should be ensured  
that the TSD circuit will not be activated during normal operation of the system.

Usage Precautions  
The input voltage, output voltage, output current and temperature conditions should be considered when  
selecting capacitors and inductors. These components should be evaluated on an actual system prototype for best  
selection.  
External components such as capacitors and inductor should be placed as close to the TB7101AF as possible.  
The TB7101AF has an ESD diode between the EN and V pins. The voltage between these pins should satisfy  
IN  
V
EN  
V < 0.3 V.  
IN  
Operation might become unstable due to board layout. In that case, add a decoupling capacitor (C ) of 0.1 μF to  
C
1μF between the SGND and V pins.  
IN  
The overcurrent protection circuits in the Product are designed to temporarily protect Product from minor  
overcurrent of brief duration. When the overcurrent protective function in the Product activates, immediately  
cease application of overcurrent to Product. Improper usage of Product, such as application of current to Product  
exceeding the absolute maximum ratings, could cause the overcurrent protection circuit not to operate properly  
and/or damage Product permanently even before the protection circuit starts to operate.
