Drives a single external transistor, switching up to 500 kHz. ## Package and mounting 8-SOIC (3.90 mm width) surface-mount package, shipped in Tube. Narrow SOIC footprint standard for low-to-medium power controllers; no heatsink pad underneath. ## Lifecycle and compliance Marked as Active on the lifecycle record — no end-of-life notice, no last-time-buy window. ROHS3 compliant. For new designs or ongoing production, this part is a current-catalog choice. If you need a higher duty cycle or synchronous rectification, the UCC2806DWTR (50% duty, dual output, synchronous rectifier) is a functional alternative in the same 8-SOIC footprint, though it carries a different pinout and control architecture.","metaTitle":"TL2845BD-8 PWM Controller, Boost/Flyback/Forward, 500kHz","metaDescription":"TL2845BD-8 current-mode PWM controller.
