PC-board layout sets the functional, electromagnetic interference (EMI), and thermal behavior of a power supply. Good layout from first prototyping on actually saves significant resources in EMI ...

Part 2 looks at how a real-world supply impedance – comprising decoupling capacitors, regulator output impedance, and PCB traces – responds to a small test current step. Part 3 examines how a varying ...

Before connecting the DC power supply to your power circuit, set the proper input voltage and verify correct polarity. Connect the dynamic load to the power supply output. Set electronic load to ...

These power-supply circuits will work with MAX86141-based PPG devices as well. In Part 2, we present pre-validated integrated power-supply circuits for use with both MAX86171- and MAX86141-based ...
