Air core inductors exhibit high Q, maintain a constant inductance value regardless of current, and can be tuned to specific inductance values by manipulating the distance between coil windings. They ...
The SC220 is a buck regulator that accepts a 2.7V to 5.5V input and produces an output as low as 1V and can drive a 650 mA load (Fig. 1). Key to its operation is a 20MHz switching frequency that ...
