IR3621PBF Datasheet 2-phase / Dual Synchronous Pwm Controller

Manufacturer: International Rectifier (now Infineon)

Overview: .. Data Sheet No.PD60231 revA IR3621 & (PbF) 2-PHASE / DUAL SYNCHRONOUS PWM CONTROLLER WITH OSCILLATOR SYNCHRONIZATION AND PRE-BIAS.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The IR3621 IC bines 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.
