BD9488F - Boost 1channel white LED driver

Description

BD9488F 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

  • Current mode DCDC converter.
  • Vout discharge circuit as shutdown.
  • LED protection circuit (OPEN protection, LED OCP protection).
  • LED protect detection as small PWM dimming signal.
  • Over-voltage protection (OVP) for the output voltage.
  • Adjustable soft start time constant.
  • The wide range of analog dimming 0.2V-3.5V.
  • The built-in transformation circuit from pulse to DC.
  • 2 PWM dimming signal.
  • The UVLO detection for the input voltage of the power stag.

Datasheet Boost 1channel white LED driver For large LCDs BD9488F ●General Description BD9488F 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. BD9488F has some protect function against fault conditions, such as the over-voltage protection (OVP), the over current limit protection of DCDC (OCP), LED over current protection (LEDOCP), the open detection of LED string. Therefore BD9488F is available for the fail-safe design over a wide range output voltage.
