STEVAL-ILL021V1

демонстрационная плата подсветки светодиодных панелей на базе драйвера светодиода.

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.
