3 Description

The TPS61372 is a full-integrated synchronous boost

converter with load disconnect built-in. The device

could support output voltage up to 16 V with 3.6-A

current limit. The input voltage ranges from 2.5 V to

5.5 V supporting the application powered by single-

cell Li-ion battery or 5 V bus.

The TPS61372 uses the peak current mode with the

adaptive off-time control based. The device works in

the PWM operation of 1.5 MHz at the moderate to

heavy load. At light load condition, the device can be

configured in either Auto PFM or forced PWM

operation via configuring the MODE pin. The Auto

PFM mode benefits of high efficiency at light load

while the forced PWM operation can keep the

switching frequency being constant across the whole

load range. The TPS61372 has a soft start to

minimize the inrush current during startup. The

TPS61372

features

of

load

disconnect

when

shutdown, and provides a hiccup output short

protection with recovering automatically after the

short releasing. In addition, the device implements

output over voltage and thermal shutdown protection.

The TPS61372 delivers a compact solution size with

1.57-mm x 1.52-mm WCSP16 package.
