PM6600 6-rows 30 mA LEDs driver with boost regulator for mobile pc LCD panels backlight
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 32 mA and they can be dimmed via a PWM signal (1% dimming dutycycle at 20 kHz can be managed). The 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 over-current and thermal shutdown) are provided
