Design ideas: Ten best 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…

GaN power transistors on standard PCB

Gallium nitride power transistor maker GaN Systems has issued an application note showing how to use its novel GaNPX packaging on FR4 PCBs.

GaNPX is a package in which the die is embedded within stacked laminate. “A series of galvanic processes replace conventional packaging techniques such as clips, wire bonds…
