UCC3813-2 - PWM

Download the UCC3813-2 datasheet PDF. This datasheet also covers the UCC2813-0 variant, as both devices belong to the same pwm family and are provided as variant models within a single manufacturer datasheet.

General Description

The UCC3813-x device family of high-speed, lowpower integrated circuits contains all of the control and drive components required for off-line and DC-toDC fixed-frequency current-mode switching power supplies with minimal parts count.

Key Features

  • 1 100-µA Typical Starting Supply Current.
  • 500-µA Typical Operating Supply Current.
  • Operation to 1 MHz.
  • 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.
  • 1.5% Tolerance Voltage Reference.
  • Same Pinout as the UCC3802 Device, UC3842 Device, and UC3842A Device Families.
