Texas Instruments UC1842/3/4/5 Current Mode PWM Controller Datasheet
The UC1842/3/4/5 family of control ICs provides necessary features to implement off-line or DC-to-DC fixed frequency current mode control schemes with a minimal external parts count. The device includes internally implemented circuits such as under-voltage lockout, a precision reference, logic for latched operation, and a PWM comparator that also provides current limit control.
