BD9394FP

Datasheet LED Drivers for LCD Backlights White LED Driver for large LCD Panels (DCDC Converter type) BD9394FP, BD9394EFV ●General Description 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 circuit protection (SCP), the open detection of LED string. Therefore BD9394FP, BD9394EFV is available for the fail-safe design over a wide range output voltage. ●Key Specification  Operating power supply voltage range: 9.0V to 35.0V  LED minimum current 30mA  LED maximum current: 150mA  Oscillator frequency: 150kHz (RT=100kΩ)  Operating Current: 4.5mA (Typ.) Operating temperature range: -40℃ to +85℃ ●Applications TV, Computer Display, Notebook, LCD Backlighting ●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)  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 tim...
