Overview
RT8497
Power MOSFET Integrated High Efficiency BCM LED Driver Controller for High Power Factor Applications
General Description
The RT8497 integrates a power MOSFET and a Boundary mode controller.
It is used for step down converters by well controlling the internal MOSFET and regulating a constant output current.
The RT8497 features a ZCS detector which keeps system operating in BCM and obtaining excellent power efficiency, better EMI performance.
The RT8497 achieves high Power Factor Correction (PFC) and low Total Harmonic Distortion of Current (THDi) by a smart internal line voltage compensation circuit which has minimized system component counts; saved both PCB size and total system cos...
