HA16120 RENESAS [Renesas Technology Corp], HA16120 Datasheet - Page 2

• Manufacturer Part Number: HA16120
• Description: Switching Regulator for Chopper Type DC/DC Converter
• Manufacturer: RENESAS [Renesas Technology Corp]

HA16114P/PJ/FP/FPJ, HA16120FP/FPJ
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-
• 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
• Externally trimmable reference voltage (Vref): ±0.2 V
• Externally adjustable undervoltage lockout points (with respect to V
• Stable oscillator frequency
• Soft start and quick shut function
Note: The reference voltage 2.5 V is under the condition of V
