HA16114P/PJ/FP/FPJ, HA16120FP/FPJ

Switching Regulator for Chopper Type DC/DC Converter

REJ03F0055-0200Z

(Previous: ADE-204-020A)

Rev.2.0

Sep.18.2003

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. 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.

These ICs can operate synchronously with external pulse, a feature that makes them ideal for power

supplies that use a primary-control AC/DC converter to convert commercial AC power to DC, then use one

or more DC/DC converters on the secondary side to obtain multiple DC outputs. Synchronization is with

the falling edge of the ‘sync’ pulse, which can be the secondary output pulse from a flyback transformer.

Synchronization eliminates the beat interference that can arise from different operating frequencies of the

AC/DC and DC/DC converters, and reduces harmonic noise. Synchronization with an AC/DC converter

using a forward transformer is also possible, by inverting the ‘sync’ pulse.

Overcurrent protection features 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 these ICs, a compact, highly efficient DC/DC converter can be designed easily, with a reduced

number of external components.
