UCC38C44 - BiCMOS Low-Power Current-Mode PWM Controller

Download the UCC38C44 datasheet PDF. This datasheet also covers the UCC28C40 variant, as both devices belong to the same bicmos low-power current-mode pwm controller family and are provided as variant models within a single manufacturer datasheet.

Description

The UCCx8C4x family are high-performance, current-mode PWM controllers.

The UCCx8C4x is an enhanced BiCMOS version with pin-for-pin compatibility to the industry standard UCx84xA family and UCx84x family of PWM controllers.

Features

  • Enhanced replacement for UCx84x and UCx84xA family with pin-to-pin compatibility.
  • Operating frequency: 1MHz Maximum.
  • 50μA Startup Current, 100μA Maximum.
  • Low operating current: 2.3mA (at fOSC = 52kHz).
  • Fast, cycle-by-cycle overcurrent limiting: 35ns.
  • Peak driving current: ±1A. Rail-to-rail output:.
  • 25ns rise time.
  • 20ns fall time.
  • ±1% accurate 2.5V error amplifier reference.
  • Trimmed oscillator discharge cur.
