SGM3846 Triple-Output AMOLED Display Power Supply GENERAL DESCRIPTION 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. The SGM3846 is available in Green TQFN-3×3-16L package. It operates over an ambient temperature range of -40℃ to +85℃. FEATURES ● 2.9V to 4.5V Input Voltage Range ● Synchronous Boost Converter (AVDD)  5.8V to 7.9V Output Voltage (Programmable)  6.1V Default Output Voltage  1.
