Description
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.
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).
- Analog current (Linear) dimming at ADIM pin.
- LED pin rating 60V.
- Individual detection and individual LED OFF for both
open and short circuits.
- Built-in ISET pin short-circuit protection cir.
