Synchronous Buck Regulator ICs for USB charging

The A8652/53 is a high output current synchronous Buck regulator which can offer tight load regulation over a wiring harness without any need for remote sense lines. This remote load regulation is achieved using an integrated open-loop correction scheme that, given a known wiring harness resistance, can adjust the output voltage based on the measured load current and a user programmable gain, which achieves ±2% accuracy at 500 mV of correction.
