Patent abstract
A battery powered headworn communication device and a method for conversion of a battery voltage in a battery powered headworn communication device, which includes providing a voltage reduction to a fixed part of the input voltage and providing a variable reduction that ensures that a minimum voltage is maintained. Preferably, the fixed part reduction and the variable reduction are performed in parallel and the fixed voltage conversion is a ⅔ conversion of the input voltage. A fixed voltage conversion and the variable conversion can be balanced according to the actual battery voltage.
