Description for the UCC24612

UCC24612 is a high performance synchronous rectifier controller and driver for standard and logic-level 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 (VDS) 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 28 V. 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.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
