STMicroelectronics Evaluation Board for SRK2001 Adaptive Synchronous Recti Fication Controller Resonant Converter for

STMicroelectronics EVL-SRK2001-HVS Evaluation Board

The STMicroelectronics EVL-SRK2001-HVS evaluation board for the SRK2001 synchronous rectification controller is suitable for LLC converter applications with higher output voltage (up to 48 V), because of the use of external sensing MOSFETs in series with DVS1, 2 pins. An external VCC voltage (12V, max. 20V) is required to supply the IC. The SRK2001 implements a control scheme for secondary-side synchronous rectification in LLC resonant converters using a transformer with a centre-tap secondary winding for full-wave rectification.

Features and Benefits

• Dual gate drive for N-channel MOSFETs
• External high voltage sensing MOSFETs and TO220 SR MOSFETs (6.85mΩ 150V rated) for application with output voltages up to 48V
• Max. Frequency: 500kHz
• Synchronous rectifier for LLC resonant converter with adaptive turn-on and turn-off
