The SG1842/43 family of control IC's provides all lockout, current limiting circuitry and start-up the necessary

to implement off-line fixed current of less than 1mA. The totem-pole output frequency, current-mode switching power supplies is optimized to drive the gate of a power with a minimum number of external components. MOSFET. The output is low in the off state to Current-mode architecture demonstrates improved provide direct interface to an N channel device. line regulation, improved load regulation, pulse- The SG1842/43 is specified for operation over by-pulse current limiting and inherent protectio.
