Synchronous Rectifier Controller

The SRC2450 Synchronous Rectifier (SR) controller ICs for switched mode power supplies with adaptive gate drive for maximum efficiency at any load.. The controller enables high efficiency designs for flyback and quasi resonant flyback topologies. A reliable and noise less operation of the SR system is insured due to the Self Synchronization feature.

This is available as soft IP, and can be customized for your specific requirements.

• Adaptive gate drive for maximum efficiency at any load
• Typical supply current in no-load operation below 250 µA
• Operates in an output voltage range between 18 V and 0 V
• Drain sense pin capable of handling input voltages up to 100 V
• Self-supplying for operation with low output voltage
• Self-supplying for high-side rectification without the use of an auxiliary winding
