RDK-801, Reference Design Board, PFS7626C, LYT6079C, LED Lighting

100W 2-stage boost and isolated flyback 3-way dimmable LED ballast using HiperPFS-4 (PFS7626C) and LYTSwitch-6 (LYT6079C) with PowiGaN™ technology. This solution is designed for low component count, high power factor, low THD and high efficiency at 100VAC to 277VAC input, 48V/2080mA output. 3-way dimming functions includes 0VDC to 10VDC analogue dimming, 10V PWM signal (frequency range: 100Hz to 3KHz), variable resistance (0 to 100Kohm). It also has integrated protection and reliability features such as output short-circuit, line and output OVP, line surge or line overvoltage and overtemperature shutdown with hysteretic automatic power recovery.
