The evolution of power distribution in the spacecraft goes into a modular architecture direction. Especially the secondary power distribution from the satellite bus to the modules can be made more efficient by applying modular design and standard power interfaces.
The FDSM series of MagI³C power modules are fully integrated DC/DC voltage converters with fixed output voltage. The modules comprise the power stage, controller, inductors, and effective operational input and output capacitors. They also come with thermal overload and short circuit protection.
The XCL230/XCL231 Series is a 36V, 600mA step-down DC/DC converter with an integrated control IC and coil. Integrating the coil makes for easier circuit board layout and minimizes malfunction and noise from the component and wiring layout.
Board level loads create greater challenges for the voltage regulators that power them. Verifying operation of these regulators requires a different approach and different form factors for test equipment
