Texas Instruments UCC24624EVM-015 Driver Evaluation Module (EVM)
Texas Instruments UCC24624EVM-015 Driver Evaluation Module (EVM) is used to replace output rectifier's diodes in an LLC power converter to synchronous rectifiers (SR) MOSFETs. The SR-MOSFETs can achieve very low conduction loss compared to rectifier diodes, significantly improving the converter's efficiency. This evaluation module has a UCC24624 LLC synchronous driver installed with two 60V, 158A 2.5 mΩ FETs. The Texas Instruments UCC24624EVM-015 includes all supporting R, Cs, and connectors to replace standard rectifier diodes with SR-MOSFETs in an LLC power converter.
Features
- Dual channel Synchronous Rectifier (SR) driver with 230V VD rating
- Fast turn-off delay to support high-frequency operation
- Proportional gate drive to extend the SR conduction time
- 30mV turn-off threshold for minimum body diode conduction
- Fixed minimum on and off time to support 700kHz switching frequency
- Low standby current 150uA with automatic sleep mode
