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