Flyback Controller, Current Control, UCC28/UCC38 Series, Texas Instruments


The isolated-flyback power supply controller provides Constant-Voltage (CV) and Constant-Current (CC) output regulation to improve transient response to large load steps. Primary-Side Regulation (PSR) eliminates the need for an Optocoupler.

The Texas Instruments 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 start-up 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.
