Regulating current supply for current load(s) with low supply voltage involves regulating d.c. voltage source supply voltage depending on voltage regulator input voltage and reference value

摘要

The method involves generating a control signal dependent at least on an input voltage (Uin) applied to a voltage regulator (2) and on a specific reference value (Vref) for the voltage regulator and regulating the supply voltage (UO) for direct voltage source (1) depending on the control signal. The reference value is a minimum demand value for the necessary input voltage for the voltage regulator. AN Independent claim is also included for the following: a circuit arrangement for regulating a current supply for current loads with a low supply voltage.
