The AW37577E is specially designed for AMOLED (Active Matrix organic LED) Display panels. It integrates two high performance boost converters, VO1 (positive voltage ELVDD) and VO3 (AVDD), one inverting buck-boost converter for VO2 (negative voltage ELVSS). These converters have excellent line and load transient response.
The VO3 can be programmed by ASWIRE, the VO1 and VO2 can be programmed by ESWIRE. All these interfaces can turn on/off corresponding converters.
