The UCC24612-1DBVT from Texas Instruments is a high-performance synchronous rectifier controller designed for N-channel MOSFET power devices. It implements near-ideal diode emulation to reduce output rectifier losses.
This controller features an operating frequency of up to 1 MHz and supports various topologies including Active Clamp Flyback, QR, DCM, CCM Flyback, and LLC. It offers MOSFET V DS sensing up to 230 V and a wide VDD range from 4 V to 28 V, allowing for direct bias from output systems. The device includes a 4-A sink and 1-A source gate driver with proportional gate drive.
Key electrical characteristics include adaptive minimum off-time for noise immunity, cycle limit pre-turn-off for improved CCM efficiency, and automatic light-load and sleep-mode management with a low standby current of 320 µA. It also provides a 16-ns typical turnoff propagation delay and a 9.5-V gate drive clamp.
The UCC24612-1DBVT is available in a SOT-23-5 package, suitable for surface mounting. It operates within a temperature range of -40°C to 125°C.
