UCC3806DW - DUAL OUTPUT PWM WSOIC16

UCC3806DW - DUAL OUTPUT PWM WSOIC16

Descrição geral do produto
The UCC3806DW is a BiCMOS Pulse Width Modulation (PWM) Controller offers exceptionally improved performance with a familiar architecture. With the same block diagram and pinout of the popular UC3846 series, the UCC3806 line features increased switching frequency capability while greatly reducing the bias current used within the device. With a typical startup current of 50µA and a well-defined voltage threshold for turn-on, these devices are favoured for applications ranging from off-line power supplies to battery operated portable equipment. 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, parallel ability with current sharing, pulse-by-pulse current limiting and push-pull symmetry correction are readily achievable with the UCC3806 series.
