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.

FEATURES

BiCMOS Version of UC3846 Family

1.4-mA Maximum Operating Current

100-µA Maximum Startup Current

0.5-A Peak Output Current

125-ns Circuit Delay

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.

Easier Parallelability

Improved Benefits of Current Mode Control

DESCRIPTION

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 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

The UCC3806 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.
