UC1842A

In Production

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
