IR3651SPBF Datasheet High Voltage Synchronous Pwm Buck Controller

Manufacturer: International Rectifier (now Infineon)

Overview: .. Data Sheet No.PD94720 IR3651SPbF HIGH VOLTAGE SYNCHRONOUS PWM BUCK.

General Description

The IR3651 is a high voltage PWM controller designed for high performance synchronous Buck DC/DC applications.

The IR3651 drives a pair of external N-MOSFETs using a programmable switching frequency up to 400kHz allows flexibility to tune the operation of the IC to meet system level requirements, and synchronization allows the simplification of system level filter design.

The output voltage can be precisely regulated using the internal 1.25V reference voltage for low voltage applications.

Key Features

  • High Voltage Operating up to 75V Programmable Switching Frequency up to 400kHz 1A Output Drive Capability Precision Reference Voltage (1.25V) Programmable Soft-Start Programmable Over Current Protection Hiccup Current Limit Using MOSFET RDS(on) sensing External Frequency Synchronization 14-pin SOIC Package.
