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.

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.
