Design ideas: Some practical ways to split a voltage rail

There are a number of reasons why an engineer would want to “split” a voltage rail in their design. Sometimes parts of the circuit, like a sensor or an IC, require a bipolar supply.

Other reasons are to make the best use of the dynamic range of your ADC if…

TDK-Lambda saves space in power supplies

Devon-based power supply maker TDK-Lambda has patented a space and cost-saving method of heat-sinking power components.

In particular, it applies to a daughter-board with mixed surface-mount (SMD) and through-hole components, that is soldered vertically into into a horizontal power supply motherboard.

The reason…
