Introduction

AI Translation

UCC24612 is a high performance synchronous rectifier controller and driver for standard and logiclevel N-channel MOSFET power devices. By implementing a near-ideal diode emulation UCC24612 reduces losses of the output rectifier and indirectly the primary side losses. The drain to source (VD S) sensing control scheme allows UCC24612 to work with multiple topologies, such as Active Clamp Flyback, QR/DCM/CCM Flyback and LLC, et.

Integrated features simplify the design effort, enabling UCC24612 to excel in a variety of applications and frequencies. The wide operating VDD and VD voltage ranges enable simple implementation in systems with outputs up to 28V. Efficiency and noise immunity is enhanced with adaptive minimum off-time. Variants UCC24612-1 and UCC24612-2 offer different minimum on-times to provide additional noise immunity. Robust operation in continuous conduction mode (CCM) is further enhanced with proportional gate-drive and CCM cycle limit pre-turn-off.

UCC24612 has multiple features that improve efficiency. The fast comparator with short propagation delays reduces switching loss. The 9.5-V gate drive clamp reduces MOSFET driving losses. Frequency dependent standby modes further decreases standby power. These features help UCC24612 be part of a greater system that meets stringent efficiency standards such as Department of Energy (DoE) Level VI and Code of Conduct (CoC) Tier 2.

UCC24612 is available in a SOT23-5 package.
