Description

The UC1842/3/ UC3844D8 /5 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. 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. UC3844D8 Features &bull; Optimized For Off-line And DC To DC Converters&bull; Low Start Up Current (<1mA)&bull; Automatic Feed Forward Compensation&bull; Pulse-by-pulse Current Limiting&bull; Enhanced Load Response Characteristics&bull; Under-voltage Lockout With Hysteresis&bull; Double Pulse Suppression&bull; High Current Totem Pole Output&bull; Internally Trimmed Bandgap Reference&bull; 500khz Operation&bull; Low RO Error Amp
