Product details

Multi-topology PWM controller for isolated and non-isolated supplies

The Texas Instruments UCC2813D-3 is a current-mode PWM controller that handles boost, flyback, and forward converter topologies — a single part number covers a range of isolated and non-isolated power stages from a 3.6 V to 12 V supply rail. With a 99% maximum duty cycle, it supports high step-up ratios in boost and flyback designs, and the transistor driver output means an external MOSFET or IGBT handles the switching — no integrated power stage, so you size the switch to the load.

Package and board-fit — 8-SOIC rework reality

The tube packaging (standard for prototype and low-volume builds) keeps the leads straight during handling; no tape-and-reel minimum to worry about for a bench run.

Frequently asked questions

Is UCC2813D-3 a good fit for a flyback converter design?

Yes — the UCC2813D-3 supports flyback topology directly, and its 99% max duty cycle allows high step-up ratios typical in flyback stages. The transistor driver output means you pair it with an external MOSFET rated for your output power.
