The SGM3842 is designed for powering AMOLED displays which requires VELVDD, VELVSS, VAVDD and VDVDD. The device integrates two Boost converters, VO1 for VELVDD and VO3 for VAVDD, a dual-phase inverting Buck-Boost converter VO2 for VELVSS and a Buck converter VO4 for VDVDD. Output voltages of all the four converters can be programmed in digital steps through the digital interface control pins (SWIRE1 & SWIRE2).

The SGM3842 is available in a Green WLCSP-2.5×2.9-42B package.
