产品详情
GENERAL DESCRIPTION

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.
