EC4217 – Linear LED Driver

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。

Features

TO-252-5L Package Type。

● Sample application circuit。

● Built in 8V~15V Zener Diode equal circuit to supply chip power which no need Start up HVNMOS, so is convenient used in 110V/220V line voltage。

Applications

● LED Bulbs
