Product details

Push-pull PWM controller for isolated supplies

The Texas Instruments UCC2808DTR-1 is a current-mode push-pull PWM controller designed for offline and DC-DC isolated power converters. It drives an external pair of power switches (no internal switches) at a fixed 50% duty cycle per output, with switching frequency up to 1 MHz. The 8.3 V to 14 V supply range and 12.5 V start-up threshold suit it for telecom, industrial, and military-grade supplies where tight regulation and transformer reset are critical.

1 MHz switching — magnetics and layout

Switching at 1 MHz reduces transformer core size. The 50% duty cycle prevents flux walking.

Temperature grade and environment

Junction temperature range is -55°C to 150°C. The 8-SOIC package dissipates heat through leads and copper plane.

Sourcing and lifecycle

TI lists the UCC2808DTR-1 as an active product with ROHS3 compliance. No last-time-buy or obsolescence notice is in effect.

Frequently asked questions

Can UCC2808DTR-1 replace UCC2808D?

UCC2808DTR-1 and UCC2808D share the same die and specifications. The difference is the shipping medium: DTR-1 is Tape & Reel, while the D suffix typically ships in tube or tray. Electrically they are identical — the replacement is valid as long as your pick-and-place or reel quantity requirements match the DTR-1 format.

What is the closest pin-compatible alternative to UCC2808DTR-1?

The UCC2808D (non-reel suffix) is the closest pin-compatible alternative — same electrical specifications, same 8-SOIC footprint. For a second-source option within the same family, the UCC2808-1 variant (if available) shares the pinout; verify the switching frequency and duty cycle match your design.
