UCC2806DWG4 (TEXAS INSTRUMENTS)

The UCC2806DWG4 is a BiCMOS Pulse Width Modulation (PWM) Controller offers exceptionally improved performance with a familiar architecture. It features increased switching frequency capability while greatly reducing the bias current used within the device. It features a typical startup current of 50µA and a well-defined voltage threshold for turn-on. Dual high current, MOSFET driving outputs and a fast current sense loop further enhance device versatility. All the benefits of current-mode control including simpler loop closing, voltage feed-forward, parallelability with current sharing, pulse-by-pulse current limiting and push-pull symmetry correction are readily achievable with this controller.
