Product Overview

The STEVAL-ILL021V1 is a LCD panels backlight demonstration boards based on the LED7707 LED driver. The LED7707 implements a high efficiency monolithic boost converter and six controlled current generators specifically designed to supply LEDs arrays used in the backlight of LCD panels. The device can manage an output voltage up to 36V(that is ten white LEDs per row). The generators can be externally programmed to sink up to 85mA and can be dimmed via a PWM signal. The device allows to detect and manage the open and shorted LED faults and to let unused rows floating. Basic protections like output overvoltage, internal MOSFET overcurrent and thermal shutdown are provided.
  • 250KHz to 1MHz adjustable switching frequency
  • Internal power MOSFET, 5V LDO for device supply
  • Constant frequency peak current mode control
  • External sync for multi device application
  • Pulse skip power saving mode at light load
  • Programmable softstart, OVP protection
  • Non latched thermal shutdown
  • Six rows with 85mA maximum current capability
  • LED failure (open and short circuit) detection
  • Less than 10µs minimum dimming time
