General Description

EC4217 is a signal segment Linear LED Driver chip, Supply current(Sink) is 120mA at VLED=25V and Pow=15V.
Other characteristic are sample application circuit (EC4217 use in 3.5 watts LED driver is only bridge rectifier and one 150kΩ resistor and one 4.7uF capacitor) and OVP( Over Voltage Protection)Function and negative coefficient output current behavior。
