Power Control IC

Descriptions

It is Adaptable to a Discontinous Mode of Operation that the IP3003 is Advanced PFC(Power Factor Correction) Controller for the High Density Switching Mode Power Supply and Electronic Ballast systems. The bunky External components are eliminated in the Internal Start-up circuits, though it is taken in Independent Boost Converter Operation. What is more, instead of the External components, the Low Pass Filter is mounted in Internal Current Sense block. Internal Clamping of the Error Amplifer and Multiplier Output improve turn on Overshoot Characteristics and Current Limiting. The One of features is able to prevent Abnormal Condition, Open Lamp & Over Voltage.
