The UTC UC3842A/3843A provide the necessary functions to implement off-line or DC to DC fixed frequency current mode, controlled switching circuits with minimal external components.
FEATURES
*Low start up current ( Typical 0.12mA )
*Automatic feed forward compensation
*Pulse-by-Pulse current limiting
*Under-voltage lockout with hysteresis
*Double pulse Suppression
*High current totem pole output to drive MOSFET directly
