UC2845BN DIP-8 Integrated

The UC384xB family of control ICs enables offline or DC to DC constant frequency current mode control schemes with a minimum number of external parts. It provides the features necessary to implement it. Internally implemented circuits, a clipped oscillator for precise DUTY CYCLE CONTROL with a pickup current of less than 0.5 mA, a precision reference clipped for accuracy at the error amplifier input, logic to guarantee latched operation, as well as It includes a PWM comparator that provides current limit control and a totem pole output stage designed to source or sink high peak current.
