The RT8487 is a Boundary mode high PF floating buck constant LED current output controller with an internal gate driver.

a ZCS detector which keeps system operating in BCM and obtaining excellent power efficiency, better EMI performance. The RT8487 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 RT8487 can use a cheap simple drum core inductor in the system instead of an EE core to obtain high efficiency. The RT.
