Description
The RT8497 integrates a power MOSFET and a Boundary mode controller. It is used for step downconverters 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 FactorCorrection(PFC) and low Total HarmonicDistortionof Current(THDi) by a smart internal line voltage compensation circuit which has minimized system component counts; saved both PCB size and total system cost.Especially, the RT8497 can use a cheap simple drum core inductor in the system instead of an EE core to obtain high efficiency.The RT8497 is housed in a SOP-8package. Thus, the components in the whole LED driver system can be made very compact.
