SGM3846 Overview
The SGM3846 is designed to drive AMOLED displays (Active Matrix Organic Light Emitting Diode) requiring VAVDD, VELVDD and VELVSS. The device integrates a boost converter for VELVDD, an inverting buck-boost converter for VELVSS and a boost converter for VAVDD, which are suitable for battery operated products. The digital interface control pin (CTRL) allows programming VAVDD, VELVDD and VELVSS in digital steps.
