Description

TheUC3842/3/4/5family of controlICs provides the necessary features to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal externalparts count.Internallyimplementedcircuits include undervoltagelockout featuring start-up current less than 1 mA, a precision reference trimmed for accuracy at the error amp input, Minidip SO14 logic to insure latched operation, a PWM paratorwhich also providescurrentlimit control,and a totem pole output stage designed to source or sink high peak current.
