Overview

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.

  • 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 circuit
  • Set Soft-Start time by external capacitor.
  • FET’s Gate (N pin) is driven by 5.8V swing
