The STEVAL-ISA056V1 is a evaluation board, based on the PM6600. It consists of a high efficiency monolithic boost converter and six controlled current generators (rows) specifically designed to supply LEDs arrays used in the backlight of LCD panels. The device can manage an output voltage up to 36 V (i.e. ten white-LEDs per row).

This device allows to detect and manage the open and shorted LED faults and to let unused rows floating. Basic protections (output over-voltage, internal MOSFET overcurrent and thermal shutdown) are provided.

  • Boost section
