    | Datasheet: | PDF (499K). Click here to download *) |  
    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. The output logic of the HA16114 is designed to control a DC/DC step-down (buck) converter or inverting converter using a P-channel power MOS FET.  |
