Texas Instruments TPS61376 4.5A Boost Converter 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 the output voltage covers up to 25V.
