25-V, 4.5-A, boost converter with 2.5% accuracy input average current limit & true disconnection

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 0.1A to 3.0A. 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 2.9V to 23V and output voltage covers up to 25V.

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 2.5mm × 2.0mm HotRod™ Lite VQFN package.
