Low Power, Dual Output, Current Mode PWM Controller

FEATURES

DESCRIPTION

• BiCMOS Version of UC1846 Families The UCC1806 family of BiCMOS PWM controllers offers exceptionally im-

proved performance with a familiar architecture. With the same block dia-

gram and pinout of the popular UC1846 series, the UCC1806 line features

• 1.4mA Maximum Operating Current

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 favored for ap-

plications ranging from off-line power supplies to battery operated portable

equipment. Dual high current, FET driving outputs and a fast current sense

loop further enhance device versatility.

• 100µA Maximum Startup Current

• 1.0A Peak Output Current

• 125nsec Circuit Delay

• Easier Parallelability

• Improved Benefits of Current Mode

Control

All the benefits of current mode control including simpler loop closing, volt-

age feed-forward, parallelability with current sharing, pulse-by-pulse current

limiting, and push-pull symmetry correction are readily achievable with the

UCC1806 series.
