Overview: .DataSheet.co.kr LP8545 High-Efficiency LED Backlight Driver for Notebooks September 23, 2011 LP8545 High-Efficiency LED Backlight Driver for.

General Description

The LP8545 is a white LED driver with integrated boost converter.

It has six adjustable current sinks which can be controlled by PWM input or with I2C-patible serial interface.

The boost converter has adaptive output voltage control based on the LED driver voltages.

Key Features

  • which make it possible to detect LED outputs with open or short fault. As well low input voltage and boost over-current conditions are monitored and chip is turned off in case of these events. Thermal de-rating function prevents overheating of the device by reducing backlight brightness when set temperature has been reached. LP8545 is available in National's LLP 24-pin package. Features.
  • High-voltage DC/DC boost converter with integrated FET.
  • with four switching frequency.
