HA16114FP

Switching Regulator for Chopper Type DC/DC Converter

Hitachi -> Renesas Electronics 

HA16114P/PJ/FP/FPJ, HA16120FP/FPJ

• Error amplifier

• Vref overvoltage protection (OVP)

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 pre-

driver 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

• Soft start and quick shut function

Note: The reference voltage 2.5 V is under the condition of VIN ≥ 4.5 V.
