PM6600 - STMicroelectronics

PM6600 6-rows 30 mA LEDs driver

The PM6600 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 a nominal output voltage up to 36 V (i.e. 10 White-LEDs per ROW). The generators can be externally programmed to sink up to 30 mA and they can .
