Features
Wide operating supply voltage range* (3.9 V to 40.0 V)
Wide operating frequency range (600 kHz maximum operation)
Direct power MOS FET driving (output current ±1 A peak in maximum rating)
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.)
Grounding the ON/
OFF
pin turns the IC off, saving power dissipation. (HA16116: I
OFF
= 10
μ
A max.;
HA16121: I
OFF
= 150
μ
A max.)
Built-in UVL circuit (UVL voltage can be varied with external resistance.)
Built-in soft start and quick shutoff functions
Note:
The reference voltage 2.5 V is under the condition of V
IN
≥
4.5 V.
