Description

The SP7656 is a PWM controlled step down (buck) voltage mode regulator co-packaged with a P-Channel FET. It operates from 4.5V to 29V making it suitable for 5V, 12V and 24V applications. The programmable overcurrent protection is based on internal FET resistance sensing and allows setting the overcurrent protection value up to a 300mV threshold (measured between VIN-LX). The SP7656 is packaged in a thermally enhanced 8-pin SO8 package making it one of the smallest converters available capable of operating from 5, 9, 12, 18 and 24VDC supplies.
