Application Information
The following examples describe 4 different ways to use LP3942 to drive different LEDs (2 RGBs, 4 RGBs, 6 Blue LEDs)
Example 1:
Normal Use – 2 RGBs
•
Charge pump in 1.5x mode, V
OUT = 4.5V
•
Non overlapping constant current mode in use
•
RGB1 and RGB2 have different control
•
Imax(R1, R2) limited to 10 mA by RR
•
Imax(G1, G2) limited to 15 mA by RG
•
Imax(B1, B2) limited to 20 mA by RB
•
Framing
→ I
LOAD(max) = 40 mA → low noise to input.
•
