描述 Description
The RT8417 is a floating buck constant current LED driver with active power factor correction (PFC). It supports high power factor across a wide range of line voltages, and it drives the converter in the boundary conduction mode (BCM) to achieve higher efficiency and better EMI performance.
A high voltage (HV) start-up device is integrated in the RT8417 to shorten the start-up time and reduce the external component count, the cost, and the volume of the driver board.
This driver can use a cheap simple drum core inductor in the system instead of an EE core. In addition, the current through the inductor is sensed directly and excellent current regulation is provided.
The RT8417 embeds comprehensive protection functions for robust designs, including LED open-circuit protection, LED short-circuit protection, VCC Under-Voltage Lockout (UVLO), VCC Over-Voltage Protection (VCC OVP), Over-Temperature Protection (OTP), and cycle-by-cycle current limitation.
