Product Overview

The UCC24630DBVT is a Synchronous Rectifier Controller with ultra-low standby current. The SR controller is a high-performance controller and driver for N-channel MOSFET power devices used for secondary-side synchronous rectification. The combination of controller and MOSFET emulates a near-ideal diode rectifier. This solution not only directly reduces power dissipation of the rectifier but also reduces primary-side losses as well, due to compounding of efficiency gains. Utilizing a volt-second balancing control method, it is ideal for flyback power supplies over a wide-output voltage range since the device is not connected directly to the MOSFET drain. The SR drive turn-OFF threshold is not dependent on the MOSFET RDS(on) which allows optimizing for maximum conduction time. Also secondary current ringing due to device and layout inductance does not affect the SR turn-OFF threshold.
  • Volt-second balance SR on-time control
  • Minimize effect of MOSFET device and layout inductance
  • CCM operation compatibility
  • Compatible with PSR and SSR control
  • Open and short pin fault protection
  • Secondary-side SR controller optimized for 5 to 24V flyback systems
  • Operating frequency up to 200kHz
  • Auto low-power detect and 110µA standby mode current
  • Rail-to-rail gate driver with 13V clamp
  • Green product and no Sb/Br
