BD9394FP White LED Driver

BD9394FP, BD9394EFV is a high efficiency driver for white LEDs and designed for large LCDs. This IC is built-in a boost DCDC converters that employ an array of LEDs as the light source. BD9394FP, BD9394EFV has some protect function against fault conditions, such as the over-voltage protection (OVP),.

BD9394FP Features

* 4ch LED constant current driver and DC/DC converter

* Maximum LED Current: 150mA

* LED Feedback Voltage: 0.37V (@NADIM=2.62V), so lower heat. Adjustable Feed Back Voltage by following LED Current setting.

* 2% LED current accuracy (NADIM=2.62V, when each LED is set to 100mA)
