HA16121FP
Description
HA16116FP/FPJ and HA16121FP/FPJ are dual-channel PWM switching regulator controller ICs for use in chopper-type DC/DC converters.
Key Features
- Grounding the ON/OFF pin turns the IC off, saving power dissipation. (HA16116: IOFF = 10 µA max.; HA16121: IOFF = 150 µA 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 VIN ≥ 4.5 V
