Constant Current IC W2RV005RM 1
Constant Current IC
W2RV005RM
Most Suitable Constant Current IC for
Driving Full Color LED
• Built-in 3 lines required to drive full color LED.
• Easy thermal design due to large power dissipation.
• Contained in the 2.9 x 2.8-mm small package.
• Can be used as a stand-alone IC or can be driven by
Omron’s W2RF004RM and W2RF002RF LED Control IC’s.
• RoHS Compliant
Ordering Information
Specifications
Absolute Maximum Ratings (Ta = 25°C)
Note: 1.
Take the power consumption and power dissipation into consideration.
2.
When implemented on a standard board (70 x 70 x 1.6 mm, Cu 3%,
Single-sided glass epoxy board). The value reduces at a rate of about
4.7 mW/
°
C when the IC is used at Ta = 25
°
C or higher.
