Built-in soft start and quick shutoff functions.Built-in UVL circuit (UVL voltage can be varied with external resistance.).Grounding the ON/OFFpin turns the IC off, saving power dissipation.Pulse-by-pulse overcurrent protection circuit with intermittent operation function (When overcurrent state continues beyond time set in timer, the IC operates intermittently to prevent excessive output current.).Direct power MOS FET driving (output current ☑ A peak in maximum rating).Wide operating frequency range (600 kHz maximum operation).Wide operating supply voltage range* (3.9 V to 40.0 V).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. The output logic is preset for booster, step-down, or inverting control in a DC/DC converter. This IC series incorporates totem pole gate drive circuits to allow direct driving of a power MOS FET.
HA16116FP/FPJ and HA16121FP/FPJ are dual-channel PWM switching regulator controller ICs for use in
