TPS61376 Boost Converter

Texas Instruments' TPS61376 is a high-voltage non-synchronous boost converter with an input average current limit and true-load disconnect functions. The input average current limit threshold can be programmed through the ILIM pin with a range of 0.1 A to 3.0 A. The isolation FET between the VP and SW pin will cut off the path between the input and output when the device is disabled. The converter has a wide input voltage range of 2.9 V to 23 V and the output voltage covers up to 25 V.

The TPS61376 implements the peak-current-mode with adaptive off-time control topology. The device works in PWM mode at moderate to heavy loads. At light-load conditions, the converter enters PFM mode to maintain high efficiency over the 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 in a 2.5 mm x 2.0 mm HotRod™ lite VQFN package.
