A power management integrated circuit (PMIC) soldered onto a printed circuit board, includes: a first output stage circuit and a second output stage circuit. In a separate power supply configuration, first and second current inflow pins of the first and second output stage circuits are soldered to first and second current inflow printed lines, respectively, wherein the first and second current inflow printed lines are not directly electrically connected to each other; and, first and second current outflow pins of the first and second output stage circuits are soldered to first and second current outflow printed lines respectively, wherein the first and second current outflow printed lines are not directly electrically connected to each other. In a cooperation power supply configuration, the first and second current inflow pins are both soldered to a common current inflow printed line of the PCB, to be electrically connected with each other.

Power management integrated circuit (PMIC) and power management system

The present disclosure provides a composition for submucosal injection including a divalent cation and an oligosaccharide obtained by exposing powdered polysaccharides to irradiation, heat, ultrasound, or ultraviolet radiation. The composition may be provided as a single solution; or the divalent cation and the oligosaccharide may be separately packaged, with the divalent cation being provided in solution form and the oligosaccharide being provided in powder form. The divalent cation may be 0.1-0.5% w/v of Ca, Mg, Fe, Cu, Ba, Zn, or any combination thereof. The oligosaccharide may be 0.5-2% w/v of degraded sodium alginate, degraded xanthan gum, degraded dextran, degraded welan gum, degraded gellan gum, degraded diutan gum, or any combination thereof. When the divalent cation is in contact with the oligosaccharide, viscosity of the composition is greater than 1000 cP, and injection pressure of the composition falls within a range of 2.5-4 kgf.
