Texas Instruments PUC24612-1DBVR

This UCC24612 multi-mode synchronous rectifier controller is a high-performance controller and driver for standard and logic-level N-channel MOSFET power devices used for secondary-side synchronous rectification in high current and high efficiency designs.

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 indirectly reduces primary-side losses as well, due to compounding of efficiency gains.

Using drain-to-source voltage sensing, the UCC24612 is ideal for Active Clamp Flyback, QR/DCM/CCM Flyback and LLC-resonant power supplies but can also be used with other power architectures. The proportion drive together with the CCM cycle limit pre-turn off design make part operate more robust in CCM operations. The wide VDD voltage range allow UCC24612 to support up to 24-V applications. The 9.5-V gate driver clamping level allows the minimum driving loss.

UCC24612 uses adaptive off time control to improve the noise immunity. This greatly simplifies the design effort and allows the controller be used in wide application and frequency ranges.

This device is available with SOT23-5 package.
