DESCRIPTION

 

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.

 

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 the UCC3806 series.

 

These devices are available in multiple package options for both through-hole and surface mount applications; and in commercial, industrial, and military temperature ranges.

 

The UCC1806 is specified for operation from --55°C to 125°C, the UCC2806 is specified for operation from --40°C to 85°C, and the UCC3806 is specified for operation from 0°C to 70°C.
