UCC2813-0/-1/-2/-3/-4/-5

UCC3813-0/-1/-2/-3/-4/-5

Low Power Economy BiCMOS Current Mode PWM

FEATURES

DESCRIPTION

100µA Typical Starting Supply Current

The UCC3813-0/-1/-2/-3/-4/-5 family of high-speed, low-power inte-

grated circuits 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.

500µA Typical Operating Supply Current

Operation to 1MHz

These devices have the same pin configuration as the UC3842/3/4/5

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

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

Internal Soft Start

Internal Fault Soft Start

Internal Leading-Edge Blanking of the

Current Sense Signal

The UCC3813-0/-1/-2/-3/-4/-5 family offers a variety of package options,

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

of critical voltage levels. Lower reference parts such as the UCC3813-3

and UCC3813-5 fit best into battery operated systems, while the higher

reference and the higher UVLO hysteresis of the UCC3813-2 and

UCC3813-4 make these ideal choices for use in off-line power supplies.

1 Amp Totem-Pole Output

70ns Typical Response from

Current-Sense to Gate Drive Output

1.5% Tolerance Voltage Reference

The UCC2813-x series is specified for operation from –40°C to +85°C

and the UCC3813-x series is specified for operation from 0°C to +70°C.

Same Pinout as UCC3802, UC3842, and

UC3842A
