Texas Instruments UCC24636EVM Rectifier Evaluation Module (EVM)

Texas Instruments UCC24636EVM Rectifier Evaluation Module (EVM) is a demonstration daughterboard that allows quick installation into an existing DCM Flyback power supply. This feature enables a user to convert an output diode rectifier into a synchronous rectifier to improve efficiency. The board is programmed by the user and may be wired directly into the output stage, even with the existing diode still in place, for ground-referenced diodes in outputs from 5V to 12V. The Texas Instruments UCC24636EVM senses the transformer magnetization's volts second (V-s) product during the primary switch on-time. It controls the onboard SR MOSFET on-time to balance the V-s product during transformer demagnetization.
