The A8652/53 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. The Remote Load Regulation control includes a 115% regulated voltage clamp in conjunction with a dynamic overvoltage protection, with OVP threshold changing with the correction voltage. The A8652/53 includes a user-configurable load-side current limit to fold back the output voltage during an output overcurrent condition. The A8652/53 regulates nominal input voltages from 4 to 36 V and remains operational when VIN drops as low as 2.6 V. When the input voltage approaches the output voltage, the duty cycle is maximized to maintain the output voltage. The A8652/53 features include externally set soft-start time, external compensation network, an EN input to enable VOUT, a SYNC/FSET input to synchronize or set the PWM switching
