The SGM3838 is designed for powering AMOLED displays which requires VELVDD, VELVSS and VAVDD. The device integrates two boost converters, VO1 for VELVDD and VO3 for VAVDD, and a dual-phase 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 (SWIRE).
The SGM3838 is available in a Green WLCSP-2.5×2.5-36B package.
