Product Overview

The UC2844N is a current-mode Pulse Width Modulation (PWM) Controller provides the necessary features to implement off-line or DC to DC fixed frequency current-mode control schemes with a minimal external parts count. Internally implemented circuits include under-voltage lockout featuring start up current less than 1mA, a precision reference trimmed for accuracy at the error amp input, logic to insure latched operation, a PWM comparator which also provides current limit control and a totem pole output stage designed to source or sink high peak current. The output stage, suitable for driving N-channel MOSFETs, is low in the off state.
  • Low start-up current
  • Automatic feed forward compensation
  • Pulse-by-pulse current limiting
  • Enhanced load response characteristics
  • Under-voltage lockout with hysteresis
  • Double pulse suppression
  • High current totem pole output
  • Internally trimmed bandgap reference
  • Low RO Error amplifier
  • Green product and no Sb/Br
