The UCC24612-1DBVR from Texas Instruments is a high-performance synchronous rectifier controller designed for standard and logic-level N-channel MOSFET power devices. It implements near-ideal diode emulation to reduce output rectifier losses.
Key electrical specifications include a wide VDD range allowing direct bias from 5-V to 28-V output systems. It features a robust gate driver with 4-A sink and 1-A source capabilities, coupled with proportional gate drive. The device supports operating frequencies up to 1 MHz, making it suitable for high-frequency applications. Adaptive minimum off-time enhances noise immunity, and a cycle limit pre-turn-off improves efficiency in CCM flyback topologies.
This controller supports various topologies such as Active Clamp Flyback, QR, DCM, CCM Flyback, and LLC. It includes automatic light-load and sleep-mode management with a low standby current of 320 µA. The MOSFET V DS sensing capability extends up to 230 V.
The UCC24612-1DBVR is available in a compact SOT-23-5 package, suitable for surface mount applications. Its operating temperature range is -40°C to 125°C.
