      SAP2844
      CURRENT MODE PWM CONTROLLER

      The SAP2844 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 0.5mA, 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.

      Main feature

      • Optimized for off-line and DC to DC converts

      • Low start up current(<0.5mA)

      • 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

      • 500kHz operation
