LED Driver ICs
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).

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.
Drivers for 3-color LEDs that have an external control interface
LV5213PL
3-channel 1-lamp LED driver (Singe RGB: 1)

Charge pump type LED driver
This is a 4-lamp white LED driver for main LCD backlights that allows the brightness to be adjusted with an
external PWM input.
Generates the optimal voltages for white LEDs with a high-efficiency charge pump type step-up circuit.
Can provide a constant current output up to a total of 140 mA.
