BD93941EFV White LED Driver

BD93941EFV and BD93941FP is a high efficiency driver for white LEDs and designed for large LCDs. These ICs are built-in a boost DCDC converters that employ an array of LEDs as the light source. BD93941EFV and BD93941FP have some protect function against fault conditions, such as the over-voltage pro.

BD93941EFV Features

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

* Maximum LED Current: 200mA

* LED Feedback Voltage: 0.37V (@ADIM=2.5V) so lower heat. Adjustable Feed Back Voltage by following LED Current setting.

* 2% LED current accuracy (ADIM=2.5V, when each LED is set to 100mA)

* Anal
