1. Description
The UC2845/3/4/5family of control ICs provides the necessary features to implement off-line or DC to DC fixed frequency
current mode control schemes with a minimal external parts count. Internallyimple-mentedcircuits include under voltagelockout
featuring start-up current less than 1 mA, a precision reference trimmed for accuracy at the error amp input, logic to insure
latched operation, a PWM compara-torwhich also providescurrent limit control,and a totem pole output stage designed to
source or sink high peak current. The output stage, suitable for driving N-Channel MOSFETs, is low in the off-state.
