3 Description

The TPS61376 is a high voltage non-synchronous

boost converter with input average current limit and

true load disconnect functions. The input average

current limit threshold can be programmed through

the ILIM pin from 0.1 A to 3.0 A. The isolation FET

between the VP and SW pin will completely cut off

the path between input and output when the device

is disabled. The TPS61376 has a wide input voltage

range from 2.9 V to 23 V and output voltage covers up

to 25 V.

The TPS61376 implements the peak current mode

with the adaptive off-time control topology. The device

works in PWM mode at moderate to heavy loads. At

the light load conditions, the device enters PFM mode

to maintain high efficiency over the entire load current

range.

The TPS61376 also integrates robust protection

features including output overvoltage protection,

cycle-by-cycle overcurrent protection and thermal

shutdown.

The TPS61376 offers a very small solution size with a

2.5-mm × 2.0-mm HotRod™ Lite VQFN package.
