IR3621PBF - 2-PHASE / DUAL SYNCHRONOUS PWM CONTROLLER

This page provides the datasheet information for the IR3621PBF, a member of the IR3621 2-PHASE / DUAL SYNCHRONOUS PWM CONTROLLER family.

Description

The IR3621 IC combines a dual synchronous buck controller and drivers, providing a cost-effective, high performance and flexible solution.

The IR3621 operates in 2-Phase mode to produce either 2-independent output voltages or current share single output for high current application.

The 180!

Features

  • Dual Synchronous Controller with 180! Out of Phase Operation Configurable to 2-Independent Outputs or Current Share Single Output Voltage Mode Control Current Sharing Using Inductor's DCR Selectable Hiccup or Latched Current Limit using MOSFET's RDS(on) sensing Latched Over-Voltage Protection Pre-Bias Start Up Programmable Switching Frequency up to 500KHz Two Independent Soft-Starts/Shutdowns Precision Reference Voltage 0.8V Power Good Output External Frequency Synchronization Thermal Protection.
