The UCC24630DBVT from Texas Instruments is a high-performance secondary-side synchronous rectifier controller optimized for flyback systems. It supports output voltages from 5V to 24V and operates at frequencies up to 200kHz.
This controller utilizes a volt-second balancing control method, minimizing the effect of MOSFET device and layout inductance. It is compatible with CCM operation and can work with both PSR and SSR control methods. The device features auto low-power detect with a standby mode current of 110µA, contributing to ultra-low standby power consumption.
Key electrical specifications include a wide VDD range of 3.6V to 28V and a rail-to-rail gate driver with a 13V clamp. It also incorporates open and short pin fault protection. The UCC24630DBVT is supplied in a SOT-23-6 package, suitable for surface mounting.
This synchronous rectifier controller emulates a near-ideal diode rectifier when paired with an N-channel MOSFET, reducing power dissipation in the rectifier and improving overall efficiency.
