• Manufacturer Part Number: ha16116fpj
• Description: Switching Regulator For Chopper Type Dc/dc Converter
• Manufacturer: Renesas Electronics Corporation.

HA16116FP/FPJ, HA16121FP/FPJ
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
• Grounding the ON/OFF pin turns the IC off, saving power dissipation. (HA16116: I
• 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 V
