Additional preview pages of the RT8497 datasheet.

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.

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 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 RT.
