UCC1808-2 - Low Power Current Mode Push-Pull PWM

Download the UCC1808-2 datasheet PDF. This datasheet also covers the UCC1808-1 variant, as both devices belong to the same low power current mode push-pull pwm family and are provided as variant models within a single manufacturer datasheet.

General Description

The UCC3808 is a family of BiCMOS push-pull, high-speed, low power, pulse width modulators.

The UCC3808 contains all of the control and drive circuitry required for off-line or DC-to-DC fixed frequency current-mode switching power supplies with minimal external parts count.

Key Features

  • 130µA Typical Starting Current.
  • 1mA Typical Run Current.
  • Operation to 1MHz.
  • Internal Soft Start.
  • On Chip Error Amplifier With 2MHz Gain Bandwidth Product.
  • On Chip VDD Clamping.
  • Dual Output Drive Stages In Push-Pull Configuration.
  • Output Drive Stages Capable Of 500mA Peak Source Current, 1A Peak Sink Current BLOCK.
