3 Description

The TPS61371 is a fully-integrated synchronous

boost converter with the load disconnect built-in.

The device supports output voltage up to 16V with

a 3.8A current limit. The output voltage can be

changed either by the feedback resistors or by the I2C

controlled reference voltage VREF. The input voltage

ranges from 2.7V to 5.5V supporting applications

powered by a single-cell Lithium-ion battery or 5V

bus.

The TPS61371 uses the peak current mode with the

adaptive off-time control topology. The device works

in PWM operation of 1.5MHz at moderate-to-heavy

loads. At the light load conditions, the device can

be configured in either auto PFM or forced PWM

operation. The mode is determined by the connection

of the MODE pin and the I2C register. Auto PFM

mode has the benefit of high efficiency at light load

while forced PWM operation keeps the switching

frequency constant across the whole load range. The

TPS61371 has a soft start to minimize the inrush

current during start-up. The TPS61371 features of

the load disconnect during shutdown and provides

latch type overvoltage and output short protections.

In addition, the device implements thermal shutdown

protection.
