Description

The UC1842 /3/4/5 family of control devices 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 1 mA, 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. UC3842N Features&bull; Optimized For Off-line and DC-to-DC Converters&bull; Low Start-Up Current (<1 mA)&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; 500-kHz Operation&bull; Low RO Error Amp
