The TPS61376 is a high voltage non-synchronous boost converter with input average current limit and 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, output overcurrent and short protection, and thermal shutdown.

The TPS61376 offers a very small solution size with a 2.5-mm × 2.0-mm VQFN package.
