HA16120FPJEL-E - Brand New RENESAS IC Chips
-
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
