ABSTRACT:
An adjustable voltage controlled current source for supplying a constant current to a load may comprise a DC to DC switcher in a commonly known topology, including boost, buck, or boost/buck. The current from the DC to DC switcher is measured with one or more current sensing resistors or one or more inductively coupled current sensing windings such as a transformer or Hall-effect device. The current measurement is then coupled to the feedback input of the DC to DC switcher. The current measurement may have a DC bias added to meet the feedback voltage requirements of the DC to DC switcher. An external current set point may be combined with the current measurement to externally set the current output.
