The Infineon Technologies IR11688STRPBF is a dual synchronous rectification controller IC designed for secondary-side control in resonant half-bridge converters. It is optimized to drive N-channel power MOSFETs, emulating Schottky diode behavior to minimize power dissipation.
Key electrical specifications include a wide Vcc operating range of 4.75V to 18V and the ability to operate up to 400kHz switching frequency. It features a 4A peak turn-off drive current and a 50ns turn-off propagation delay. The controller directly senses MOSFET drain voltage up to 200V.
This IC is housed in an 8-SOIC package suitable for surface mounting. Its features include programmable minimum on-time, anti-bounce logic, UVLO protection, and cycle-by-cycle MOT protection, making it suitable for applications like desktop SMPS, server SMPS, AC-DC adapters, and telecom SMPS.
Typical applications include desktop SMPS, server SMPS, AC-DC adapters, LCD & PDP TVs, and telecom SMPS. The device is designed for improved noise immunity and compatibility with low standby power requirements.
