Sanyo EP92H - Manual (Page 14)

SANYO provides LED drivers that support automatic gradation production using full-color LEDs and can provide high-capacity
outputs up to a total of 500 mA using a switching power supply technique as well as white LEDs for backlights using a charge
pump method optimal for white LEDs.

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).
