低功耗,双路输出,电流模式PWM控制器 LOW-POWER, DUAL-OUTPUT, CURRENT-MODE PWM CONTROLLER
DESCRIPON
The UCC3806 family of BiCMOS PWM controllers 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 50 μA and a well defined voltage threshold for turn-on, these devices are favored 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.
