Typical Application Circuit for A8652 Wide Input Voltage, Synchronous USB Buck Regulator with Remote Load Regulation. The A8652 is a high output current synchronous buck regulator that provides tight load regulation over a wiring harness without the need for remote sense lines. This remote load regulation is achieved with an integrated open-loop correction scheme that, given a known wiring harness resistance, adjusts the output voltage based on the measured load current and a user-programmable gain, achieving ±2% accuracy at 500 mV of correction
