PM6602 Description
The PM6602 consists of a high-efficiency monolithic boost converter and eight controlled current generators (ROWs), specifically designed to supply LED arrays used in the backlights of LCD panels. The device can manage a nominal output voltage of up to 36 V. The generators can be externally programmed to sink up to 30 mA and they can be dimmed in two different modes:.
