BD93941FP - White LED Driver

Download the BD93941FP datasheet PDF. This datasheet also covers the BD93941EFV variant, as both devices belong to the same white led driver family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.

Datasheet LED Drivers for LCD Backlights White LED Driver for large LCD Panels (DCDC Converter type) BD93941EFV BD93941FP General 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. BD93941EFV and BD93941FP have 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 BD93941EFV and BD93941FP are available for the fail-safe design over a wide range output voltage. Key Specification  Operating power supply voltage range: 9.0V to 35.
