Description

The HA16114P/FP/FPJ and HA16120FP/FPJ are single-channel PWM switching regulator controller ICs suitable for chopper-type DC/DC converters. Integrated totem-pole output circuits enable these ICs to drive the gate of a power MOSFET directly. The output logic of the HA16120 is designed to control a DC/DC step-up (boost) converter using an N-channel power MOS FET. The output logic of the HA16114 is designed to control a DC/DC step-down (buck) converter or inverting converter using a P-channel power MOS FET.

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

? Soft start and quick shut function

Functions

? 2.5 V voltage reference

? Sawtooth oscillator (Triangle wave)

? Overcurrent detection

? External synchronous input

? Totem-pole output

? Undervoltage lockout (UVL)

? Error amplifier

? Vref overvoltage protection (OVP)
