UCC3810 - BiCMOS controller

Download the UCC3810 datasheet PDF. This datasheet also covers the UCC2810 variant, as both devices belong to the same bicmos controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The UCC3810 is a high-speed BiCMOS controller integrating two synchronized pulse width modulators for use in off-line and dc-to-dc power supplies.

The UCC3810 family provides perfect synchronization between two PWMs by usin g the same oscillator.

Key Features

  • Single Oscillator Synchronizes Two PWMs.
  • 150-µA Startup Supply Current.
  • 2-mA Operating Supply Current.
  • Operation to 1 MHz.
  • Internal Soft-Start.
  • Full-Cycle Fault Restart.
  • Internal Leading-Edge Blanking of the Current Sense Signal.
  • 1-A Totem Pole Outputs.
  • 75-ns Typical Response from Current Sense to Output.
  • 1.5% Tolerance Voltage Reference N.
