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.","metaTitle":"UCC2808DTR-1 Push-Pull PWM Controller, 1 MHz, 8-SOIC","metaDescription":"UCC2808DTR-1 offline push-pull PWM controller from TI. 1 MHz switching, 50% duty cycle, 8.3–14 V supply, -55 to 150°C.

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."},{"question":"What is the closest pin-compatible alternative to UCC2808DTR-1?","answer":"The UCC2808D (non-reel suffix) is the closest pin-compatible alternative — same electrical specifications, same 8-SOIC footprint.
