LED Control IC

W2RG012RN

Terminal Designation

Note: 1. When CE terminal is not used, keep it in L fixing condition. (This does not apply to CE-D8 mode.)

2. CAP terminal is connected to capacitor for power smoothing. Connect a 0.1

μF capacitor between the terminal and GND.

3. A 100 k

Ω pullup resistance is built in the RST terminal. It is recommended that when the terminal is not used, a 0.1 μF capacitor be connected

between the terminal and GND to ensure stable operation.

4. Leave unused output terminals open.
