Sanyo EP92H manual LED Driver ICs

LED Driver ICs

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.

Switching power supply LED drivers

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).
