HA16116FP/FPJ, HA16121FP/FPJ

Switching Regulator for Chopper Type DC/DC Converter

REJ03F0056-0200Z

Rev.2.0

Description

HA16116FP/FPJ and HA16121FP/FPJ are dual-channel PWM switching regulator controller ICs for use in

chopper-type DC/DC converters.

This IC series incorporates totem pole gate drive circuits to allow direct driving of a power MOS FET. The

output logic is preset for booster, step-down, or inverting control in a DC/DC converter. This logic

assumes use of an N-channel power MOS FET for booster control, and a P-channel power MOS FET for

step-down or inverting control.

HA16116 includes a built-in logic circuit for step-down control only, and one for use in both step-down and

inverting control. HA16121 has a logic circuit for booster control only and one for both step-down and

inverting control.

Both ICs have a pulse-by-pulse current limiter, which limits PWM pulse width per pulse as a means of

protecting against overcurrent, and which uses an on/off timer for intermittent operation. Unlike

conventional methods that use a latch timer for shutdown, when the pulse-by-pulse current limiter

continues operation beyond the time set in the timer, the IC is made to operate intermittently (flickering

operation), resulting in sharp vertical setting characteristics. When the overcurrent condition subsides, the

output is automatically restored to normal.

The dual control circuits in the IC output identical triangle waveforms, for completely synchronous

configuring a compact, high efficiency dual-channel DC/DC converter, with fewer external components

than were necessary previously.
