描述 Description

Low IQ LCD Bias for LCD Display

DW8769L, with low IQ (0.55mA), is a power supply IC to support general positive/negative
driven LCD. It is integrated with a boost regulator, LDO and charge pump to generate dual output voltages. The device uses a single inductor scheme in order to provide smaller size
as well as high efficiency. With its input voltage range from 2.5V to 5.5V, it is optimized for products powered by singlecell batteries and output currents min. 80mA. DW8769L offers low
quiescent current, making it well suited for application, which needs for longer battery life.
