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.

include a pulse-by-pulse current limiter that can reduce the width of individual PWM pulses, and an intermittent operating mode controlled by an on-off timer. Unlike the conventional latched shutdown function, the intermittent operating function turns the IC on and off at controlled intervals when pulse-by-pulse current limiting continues for a programmable time. This results in sharp vertical settling characteristics. Output recovers automatically when the overcurrent condition subsides. Using.
