IR3629MPBF - HIGH FREQUENCY SYNCHRONOUS PWM BUCK CONTROLLER

Download the IR3629MPBF datasheet PDF. This datasheet also covers the IR3629A variant, as both devices belong to the same high frequency synchronous pwm buck controller family and are provided as variant models within a single manufacturer datasheet.

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.

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.

Data Sheet No. PD94726 www.DataSheet4U.com IR3629/IR3629A MPbF 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. Protection such as Pre-Bias startup, hiccup current limit and thermal shutdown provide the required system level security in the event of fault conditions.
