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), the over current limit protection of DCDC (OCP), the short .
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)
Analog current (Linear) dimming at NADIM pin
LED pin rating 60V
Individual detection and individual LED OFF for both
open and short circuits
Built-in ISET pin short-circuit protection circuit
Set Soft-Start time by external capacitor.
FET’s Gate (N pin) is driven by 5.8V swing
Built-in Vout discharge circu.
