LED Driver ICs
These are LED drivers that can provide a high-capacity output up to a total of 500 mA using a switching power supply
technique, and cover applications such as main LCD backlights, sub-LCD backlights, camera flash systems, and full-
color LED indicators.
Gradation production using full-color LEDs is also supported (automatic).
