Description
HA16116FP/FPJ and HA16121FP/FPJ are dual-channel PWM switching regulator controller ICs for use in
chopper-type DC/DC converters.
This IC series incorporates totem pole gate drive circuits to allow direct driving of a power MOS FET. The output logic is preset for booster, step-down, or inverting control in a DC/DC converter. This logic assumes use of an N-channel power MOS FET for booster control, and a P-channel power MOS FET for step-down or inverting control.

Features
•  Wide operating supply voltage range* (3.9 V to 40.0 V)
•  Wide operating frequency range (600 kHz maximum operation)
•  Direct power MOS FET driving (output current ±1 A peak in maximum rating)
•  Pulse-by-pulse overcurrent protection circuit with intermittent operation function (When overcurrent state continues beyond time set in timer, the IC operates intermittently to prevent excessive output current.)
•  Grounding the ON/OFFpin 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.

Functions
•  2.5 V reference voltage (Vref) regulator
•  Triangle wave form oscillator
•  Dual overcurrent detector
•  Dual totem pole output driver
•  UVL (under voltage lock out) system
•  Dual error amplifier
•  Vref overvoltage detector
•  Dual PWM comparator
