2 Channel Charge Pump

Supply for TFT-LCD

EC6585

General Description

The EC6585 is

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’s). 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.
