ABSTRACT:
A circuit, system and method determine the control voltage for a DC-DC converter. A control module determines a raw battery voltage and an operating temperature. It references a look up table to determine a voltage regulator control voltage based on the battery voltage and the operating temperature during normal operation. In some cases, the control module also uses a level of interference to determine the control voltage.
