It operates as a voltage-mode or current-mode controller depending on external compensation, and is commonly used in flyback, boost, and forward converter topologies. The part is classified as an analog switching voltage regulator and is for low-to-medium volume assembly lines. ## Active lifecycle — no obsolescence watch needed For a BOM line this means no last-time-buy planning or substitute qualification is required at this time.","metaTitle":"UCC3805DTR/81222 Switching Voltage Regulator, Active","metaDescription":"UCC3805DTR/81222 analog switching voltage regulator from TI, active lifecycle, sourced to order.
