SGMICRO SGM3836DYTQ16G/TR

The SGM3836D is specifically designed to power AMOLED displays requiring V_AVDD, V_ELVDD, and V_ELVSS. The device integrates two boost converters — VO1 for V_ELVDD and VO3 for V_AVDD — along with an inverting buck-boost converter VO2 for V_ELVSS. The output voltages of all three converters can be programmed in digital steps via the digital interface control pin (CTRL). The SGM3836D is available in a Green TQFN-3×3-16L package, with an operating temperature range of -40°C to +85°C.
