IRU3137 - 8-PIN SYNCHRONOUS PWM CONTROLLER

General Description

The IRU3137 controller IC is designed to provide a low cost and high performance synchronous Buck regulator for on-board DC to DC converter applications.

The output voltage can be set as low as 0.8V and higher voltage can be obtained with an external voltage divider.

Key Features

  • 1A Peak Output Drive Capability 0.8V Reference Voltage Shuts off both drivers at shorted output and shutdown Operating with single 5V or 12V supply voltage Stable with ceramic capacitors Internal 200KHz Oscillator Soft-Start Function Protects the output when control FET is shorted Synchronous Controller in 8-Pin Package.
