SGM3851A Overview
The SGM3851A is designed for powering AMOLED displays which require VAVDD, VELVDD and VELVSS. The device integrates two boost converters, VO1 for VELVDD and VO3 for VAVDD, and an inverting buck-boost converter VO2 for VELVSS. Output voltages of all the three converters can be programmed in digital steps through the digital interface control pin (CTRL).
