The power supply accepts 8 to 16 volts and produces 12 volts. The topology is SEPIC (single-ended primary inductance converter), the advantage being the ability to convert up or down with a minimum of parts and maximum efficiency. [...] the power supply is good for about 8 amps output and can power the system while [...]
An interesting DC/DC converter IC is available from Linear Technology. The LT1615 step-up switching voltage regulator can generate an output voltage of up to +34 V from a +1.2 to +15-V supply, using only a few external components. The tiny 5-pin SOT23 package makes for very compact construction. This IC can for example be used [...]
Simple add-on for a single-rail supply ±2.5V to ±15V output This simple unit provides a dual-rail variable output ranging from ±2.5V to ±15Vdc with precise tracking of the positive and negative output voltages, still retaining the current limiting and short-proof capabilities of the “master” circuit. As the purpose of such a dual-rail design is to [...]
