ANX6585数据手册HYSiC中文资料规格书

描述 Description

The ANX6585 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’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 ANX6585C performs truly shutdown. It means VSP is 0V when EN is low. The VSP of ANX6585D is pre-charged to VIN when EN is not pulled high. Both ANX6585C and ANX6585D provide the self-discharge function when EN is pulled down.

     The ANX6585 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.
