Linear LED Driver
EC4216
GENERAL DESCRIPTION
EC4216 is a Linear LED Driver of 6-segment LED switch, and its current of each segment in Pow=15V and
V_D=20V can provide 60mA by Sink. In addition, it contains simple application circuit, every few external
components (e.g. a bridge rectifier external resistor and a 4.7uF capacitor are required only in use of 2 Watts),
OVP (Over Voltage Protection) Function, and Negative Temperature Coefficient Output.
FEATURES
● SOP-8L(Exposed Pad) package
● Simple application circuit
● Built-in 8V~15V Zener Diode Equivalent circuit, provides for internal circuit, without Start up HVNMOS,
convenient for 110V/220V power use.
APPLICATIONS
● LED Bulbs
ABSOLUTE MAXIMUM RATINGS
● I_Z=10mA.
● Pow=16.5V.
● D1~D6 Break Down Voltage=600V at Pow=0V.
● Operating Temperature Range：-40℃ to 120℃
● Storage Temperature Range：-40℃ to 140℃
● ESD Level………………(H.B.M) 2KV
(M.M) 200V
Note:
Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional
Operation under these conditions is not implied. Continuous operation of the device at the absolute rating level
may affect device reliability.
