The UC3842/3/4/5 family 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. Internally
implemented circuits include undervoltage lockout featuring start-up current
less than 1mA, a precision reference trimmed for accuracy at the error amp
input, logic to insure latched operation, a PWM comparator which also provides
current limit control, and a totem pole output stage designed to source or sink
high peak current.
