IR11672ASTRPBF Description

Short technical summary and product information.

The Infineon IR11672ASPBF is an ADVANCED SMARTRECTIFIERTM CONTROL IC designed for secondary-side synchronous rectification in isolated Flyback and resonant half-bridge converters. This IC drives N-Channel power MOSFETs to emulate Schottky diode rectifiers, sensing the drain-to-source voltage to control MOSFET switching near zero current transition.

 

Key electrical specifications include a 200V drain-source voltage (VD), a maximum switching frequency of 500 KHz, and a 10.7V gate drive clamp. It offers a 7A peak turn-off drive current and fast propagation delays, with turn-off at 50ns and turn-on at 60ns typical. The operating VCC range is from 11.3V to 20V. It also includes features like anti-bounce logic, UVLO protection, and micropower start-up with ultra-low quiescent current.

 

This controller is compatible with various power supply designs, including LCD & PDP TVs, telecom SMPS, AC-DC adapters, ATX SMPS, and server SMPS. It is designed for lead-free processing and is compatible with standby power standards like Energy Star and CECP.

 

The IR11672ASPBF is available in an 8-lead SOIC package, suitable for surface mount applications. The standard package quantity for tape and reel is 2500 units.
