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).\nThe SGM3851A is available in a Green TQFN-3×3-16L package. It operates over an ambient temperature range of -40℃?to +85℃.\n
