IR3629MPBF Datasheet High Frequency Synchronous Pwm Buck Controller

Manufacturer: International Rectifier (now Infineon)

Overview: Data Sheet No. PD94726 www.DataSheet4U.com IR3629/IR3629A MPbF.

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

General Description

The IR3629/IR3629A is a PWM controller designed for high performance synchronous Buck DC/DC applications.

The IR3629/IR3629A drives a pair of external N-MOSFETs using a fixed 600kHz (300kHz “A version”) switching frequency allowing the use of small external components.

The output voltage can be precisely regulated using the internal 0.6V reference voltage for low voltage applications.

Key Features

  • Internal 600kHz Oscillator (300kHz “A version”) Operates with Single 5V or 12V Supply Programmable Over Current Protection Hiccup Current Limit Using MOSFET RDS(on) sensing Precision Reference Voltage (0.6V) Programmable Soft-Start Programmable PGood output Pre-Bias Start-up Thermal Protection 12-Lead MLP Package Distributed Poi.
