- Page 3 Using the UCC24612-1EVM Introduction The UCC24612-1EVM evaluation module (EVM) is used to convert the output rectifier of a flyback converter from a diode to a synchronous rectifier (SR) FET to investigate and evaluate the efficiency benefits of using an SR over a rectifier diode.
- Page 4 Four test points and a terminal block provide access to several important nodes in the SR control circuit. Refer to the schematic diagram of the UCC24612-1EVM in Figure 3. In a low-side rectifier application, the EVM can connect directly to the converter’s output, provided that the output voltage is in the range of 4 V...

UCC24612-1EVM Used in High-Side Rectifier Application If the magnitude of voltage across TP1 and TP2 is less than 28 V please remove R2 that is populated on the EVM ( 20 kΩ) and set R2 to 0 to 10 ohms and remove 27-V Zener diode D1 from the board.
- Page 8 Application Test Data www.ti.com Application Test Data The UCC24612-1EVM was used in a synchronous rectifier in both a high side and low side application in an offline (V = 85 V to 265 V RMS), 20-V (V ), 60-W application. The controller used in this design was a UCC28740 secondary side regulated, variable-frequency flyback controller that had a maximum switching frequency of roughly 85 kHz.
