UCC2810 Datasheet Bicmos Controller

Manufacturer: Texas Instruments

Overview: UCC2810 UCC3810 www.ti.com SLUS162D – FEBRUARY 1999 – REVISED FEBRUARY 2007 DUAL CHANNEL SYNCHRONIZED CURRENT-MODE.

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.

The oscillator’s sawtooth waveform can be used for slope compensation if required.

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.
