Description

The UC384XT family of control ICs provides the necessary features to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal external parts count.

Key Features

  • to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal external parts count
  • The output stage, suitable for driving N-Channel MOSFETs, is low in the offstate
  • Differences between members of this family are the under-voltage lockout thresholds and maximum duty cycle ranges
  • The UC3842T and UC3843T can operate to duty cycles approaching 100%
  • Vi 7 34V GROUND 5 UVLO S/R 5V REF INTERNAL BIAS VREF GOOD LOGIC RT/CT 4 OSC ERROR AMP
