LED Control IC
W2RF004RM
Most Suitable IC for Controlling LED
Effects within Applications
⢠Free-running PWM gradation control, with up to 1,024 levels, en-
ables the representation of beautiful fade-in and fade-out effects.
⢠CPU load can be reduced by controlling lighting gradation and speed.
⢠Up to 49 pieces of this IC can be connected on the same serial bus
communication line. Device group setting is also possible.
⢠Independant control of up to 9 Lines.
⢠Use with Omronâs W2RV005RM Constant Current IC to directly
drive multiple LEDâs in series.
⢠RoHS Compliant

Note: 1. Take the power consumption and power dissipation rating
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
8.48 mW/°C when the IC is used at Ta = 25°C or higher.
