Low-Power BiCMOS Current-Mode PWM

FEATURES

DESCRIPTION

• 100^µA Typical Starting Supply Current

The UCC1800/1/2/3/4/5 family of high-speed, low-power integrated cir-

cuits contain all of the control and drive components required for off-line

and DC-to-DC fixed frequency current-mode switching power supplies

with minimal parts count.

• 500^µA Typical Operating Supply

Current

• Operation to 1MHz

• Internal Soft Start

These devices have the same pin configuration as the UC1842/3/4/5

family, and also offer the added features of internal full-cycle soft start

and internal leading-edge blanking of the current-sense input.

• Internal Fault Soft Start

The UCC1800/1/2/3/4/5 family offers a variety of package options, tem-

perature range options, choice of maximum duty cycle, and choice of

critical voltage levels. Lower reference parts such as the UCC1803 and

UCC1805 fit best into battery operated systems, while the higher refer-

ence and the higher UVLO hysteresis of the UCC1802 and UCC1804

make these ideal choices for use in off-line power supplies.

The UCC180x series is specified for operation from –55^oC to +125^oC,

the UCC280x series is specified for operation from –40^oC to +85^oC, and

the UCC380x series is specified for operation from 0^oC to +70^oC.

• Internal Leading-Edge Blanking of the

Current Sense Signal

• 1 Amp Totem-Pole Output

• 70ns Typical Response from

Current-Sense to Gate Drive Output

• 1.5% Tolerance Voltage Reference

• Same Pinout as UC3842 and

UC3842A
