UCCx813-x Low-Power Economy BiCMOS Current-Mode PWM Features
100-µA Typical Starting Supply Current 500-µA Typical Operating Supply Current Operationto1 MHz Internal Soft Start Internal Fault Soft Start Internal Leading-Edge Blankingof the Current-
Sense Signal 1-A Totem-Pole Output 70-ns Typical Response from Current-Senseto
Gate-Drive Output 1.5% Tolerance Voltage Reference Same Pinoutas the UCC3802 Device, UC3842
Device, and UC3842A Device Families Applications Switch Mode Power Supplies (SMPS) DC-DC Converters Power Modules Industrial PSUs Battery Operated PSUs Description
The UCC3813-x device family of high-speed, low-
power integrated circuits contains allof the control
and drive components requiredfor off-line and DC-to- fixed-frequency current-mode switching power
supplies with minimal parts count.
These devices have the same pin configuration as
the UC384x device family, and also offer the added
featuresof internal full-cycle soft start and internal
leading-edge blankingof the current-sense input.
The UCC3813-x device family offersa variety of
package options, temperature-range options, choice maximum duty cycle, and choiceof critical voltage
levels. Devices with lower reference voltage suchas
the UCC3813-3 and UCC3813-5fit best into battery
(1) Forall available packages, see the orderable addendumat
the endofthe data sheet.
