This circuit shows how you can get a ±15V lA split supply, plus a separate 5V, 200mA logic supply, just using a pair of plugpacks or 'brick' type supplies, like those used to power and charge laptops. These are readily available, relatively inexpensive, small and light. The resulting device will likely be smaller and lighter than a transformer-based solution. Before stacking switchmode supplies as shown here, if the supply has an Earth pin, use a DMM set to measure ohms to ensure that there is no connection (when unplugged) between the Earth pin and either output. If there is, they are not suitable for stacking. mis ran is powerec
