BD9394EFV - White LED Driver

This page provides the datasheet information for the BD9394EFV, a member of the BD9394FP White LED Driver family.

Datasheet Summary

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.

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.

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.
