... Switching Regulator for Chopper Type DC/DC Converter Description The HA16114P/FP/FPJ and HA16120FP/FPJ are single-channel PWM switching regulator controller ICs suitable for chopper-type DC/DC converters. Integrated totem-pole output circuits enable these ICs to drive the gate of a power MOSFET directly. The output logic of the HA16120 is designed to control a DC/DC step-up (boost) converter using an N-channel power MOS FET ...
