UC2843
DESCRIPTION
The UC3842/3/4/5family of control ICs 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 m A, 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. The output...
