The SGM38046 is a power source device for biasing small AMOLED panels. It can be powered from a single-cell Lithium-Ion/polymer battery or a DC supply in the range of 2.7V to 5.5V to provide OVDD, OVSS and AVDD voltage sources for the AMOLED panel. Two interim voltage rails (positive and negative) are generated by the integrated buck-boost converter and an inverting charge pump inverter. These rails are regulated by LDOs to get clean and low ripple positive (AVDD and OVDD) and negative (OVSS) outputs. This device is optimized for symmetric output to get the highest efficiency from the charge pump inverter.

The SGM38046 is available in a Green WLCSP-2×2-16B package.
