Product Overview

The UCC28C40D is a low-power BiCMOS current-mode Pulse Width Modulation (PWM) Controller with pin-for-pin compatibility to the industry standard UC384xA family and UC384x family of PWM controllers. It provides necessary features to control fixed frequency and peak current-mode power supplies. The device offers high-frequency operation up to 1MHz with low start-up and operating currents, thus minimizing start-up loss and low operating power consumption for improved efficiency. It features a very fast current-sense-to-output delay time of 35ns and a ±1A peak output current capability with improved rise and fall times for driving large external MOSFETs directly.
  • Rail-to-rail output swings with 25ns rise and 20ns fall times
  • ±1% Initial trimmed
  • 2.5V Error amplifier reference
  • Trimmed oscillator discharge current
  • Under-voltage lockout
