BD9394EFV Datasheet White Led Driver

Manufacturer: ROHM

Overview: Datasheet LED Drivers for LCD Backlights White LED Driver for large LCD Panels (DCDC Converter type) BD9394FP, BD9394EFV.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.

Key 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 c.
