ActivePWM CONTROLLER FLYBACK OR FORWARD - LOW START-UP CURRENT (0.5MA MAX.) 500KHZ OP
Description
General part information
UC2843A Series
Control ICs provides all the necessary features to implement off-line fixed-frequency, current-mode switching power supplies with a minimum of external components. The current mode architecture demonstrates improved load regulation, pulse-by- pulse current limiting and inherent protection of the power supply output switch
