EV6001DN-00D
WLED Driver
Evaluation Board
The Future of Analog IC Technology
GENERAL DESCRIPTION
The EV6001DN-00D is an evaluation board for
the WLED driver application. It can drive 6
20mA strings of WLEDs with up to 10 WLEDs
per string. EV6001DN-00D has good current
balance among 6 strings. It also has PWM
dimming, EN function, and open circuit voltage
protection.
This device is available in an 8-pin SOIC
package with an exposed pad.
