General Description<\/h3>\n\n\n\n

The EC6585 is a high perfomance charge pump converter to generate positive and negative voltage
supply optimized for small to medium size thin-film transistor(TFT) liquid crystal displays (LCD\u2019s).
The positive charge-pump controller provides 2x positive output voltage PAVDD and fixed -1x ratio of negative voltage NAVDD to supply the TFT LCD. To minimize the inrush current a built-in soft start circuit sets the soft
start period.
The EC6585 is convinient to use and requires only 5 small and low-cost ceramic capacitors.It is availiable in the TDFN-12L package which reduces board size and make the FPC or PCB layout design easier.<\/p>\n\n\n\n
