Product Overview

The LP8550TLE/NOPB is a high-efficiency LED Backlight Driver with an integrated boost converter. It has six adjustable current sinks which can be controlled by PWM input or with I²C-compatible serial interface. The boost converter has adaptive output voltage control based on the LED driver voltages. This feature minimizes the power consumption by adjusting the voltage to lowest sufficient level in all conditions. LED outputs have 8-bit current resolution and up to 13-bit PWM resolution with additional 1- to 3-bit dithering to achieve smooth and precise brightness control. Proprietary phase shift PWM control is used for LED outputs to reduce peak current from the boost converter, thus making the boost capacitors smaller. The phase shifting scheme also eliminates audible noise. Automatic PWM dimming at lower brightness values and current dimming at higher brightness values can be used to improve the optical efficiency. Internal EEPROM is used for storing the configuration data.
  • High-voltage DC/DC boost converter with integrated FET
  • I²C and PWM brightness control
  • Automatic PWM and current dimming for improved efficiency
  • PWM output frequency and LED current set through resistors
  • Six LED outputs with LED fault (short/open) detection
  • Low input voltage, over-temperature, overcurrent detection and shutdown
  • Minimum number of external components
  • Green product and no Sb/Br
