A current source provides electrical energy with a constant current. The implication is that if the resistance of the load changes the current source will vary the voltage to compensate.

Another 1A, 20V PWM DAC current source, but this time it uses boost preregulator that can run from a 5V regulated or unregulated supply.

The chip-scale power converter addresses the chip-level bottleneck and the system-level power delivery network (PDN) ...
