UCC2813-x-Q1 Low-Power Economy BiCMOS Current-Mode PWM

1 Features

3 Description

The UCC2813-x-Q1 device family of high-speed, low-

power integrated circuits contains 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.

•

Qualified for automotive applications

AEC-Q100 qualified with the following results:

–

Device temperature grade 1: –40°C to 125°C

T_A

–

Device HBM classification level 2: ±2 kV

These devices have the same pin configuration as

the UC284x device family, and also offer the added

features of internal full-cycle soft start and internal

leading-edge blanking of the current-sense input.

Device CDM classification level C5: >1000 V

•

100-µA typical starting supply current

500-µA typical operating supply current

Operation to 1 MHz

The UCC2813-x-Q1 device family offers a variety of

package options, choice of maximum duty cycle, and

choice of critical voltage levels. Devices with lower

reference voltage such as the UCC2813-3-Q1 and

UCC2813-5-Q1 fit best into battery operated systems,

while the higher reference and the higher UVLO

hysteresis of the UCC2813-2-Q1 device and

UCC2813-4-Q1 device make these ideal choices for

use in off-line power supplies.

Internal soft start

Internal fault soft start

Internal leading-edge blanking of the current-

sense signal

•

1-A totem-pole output

70-ns typical response from current-sense to gate-

drive output

The UCC2813-x-Q1 device series is specified for

operation from –40°C to 125°C.

•

1.5% tolerance voltage reference

Same pinout as the UCC3802 device, UC3842

device, and UC3842A device families
