SGM3838A数据手册SGMICRO中文资料规格书

描述 Description

The SGM3838A is designed for powering AMOLED displays which require 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 SGM3838A is available in a Green WLCSP-2.5×2.5-36B package.
