PM6600 Description
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. The generators can be externally programmed to sink up to 30 mA and they can be dimmed via a PWM signal (1% dimming dutycycle at 20 kHz can be managed).
