HA16114PJ
Description
The HA16114P/FP/FPJ and HA16120FP/FPJ are single-channel PWM switching regulator controller ICs suitable for chopper-type DC/DC converters.
Key Features
- Wide supply voltage range: 3.9 V to 40 V*
- Maximum operating frequency: 600 kHz
- Able to drive a power MOS FET (±1 A maximum peak current) by the built-in totem-pole gate predriver circuit
- Can operate in synchronization with an external pulse signal, or with another controller IC
- Pulse-by-pulse overcurrent limiting (OCL)
- Intermittent operation under continuous overcurrent
- Low quiescent current drain when shut off by grounding the ON/OFF pin HA16114: IOFF = 10 µA (max) HA16120: IOFF = 150 µA (max)
- Externally trimmable reference voltage (Vref): ±0.2 V
- Externally adjustable undervoltage lockout points (with respect to VIN)
- Stable oscillator frequency
