Buck switching-power converters are the most common method used to efficiently step down positive input voltages. Some applications require an additional low power negative output voltage. Often, for ...

Many systems require a low-power supply in addition to the main supply. A typical example is when an analog front-end amplifier needs ±5 V, while the main digital circuitry requires +5 V only. For ...

The age of creative thinking in dc/dc converters is not over. So-called “new” topologies may appear periodically, but if they are not resonant types, almost invariably they are just variations of the ...

Frequently, the lowest possible cost is the fundamental challenge that engineers encounter when designing power converters. When multiple output voltages are required, it is often tempting to provide ...
