SGM3851A Triple-Output AMOLED Display Power Supply GENERAL DESCRIPTION The SGM3851A is designed for powering AMOLED displays which require VAVDD, VELVDD and VELVSS. The device integrates two boost converters, VO1 for VELVDD and VO3 for VAVDD, and an 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 (CTRL). The SGM3851A is available in a 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 (ELVDD)  4.6V to 5.0V Output Voltage with 100mV Steps  4.6V Default Output Voltage  1.
