Abstract
Circuits and methods system for a DC-to-DC conversion using the inductance of a motor coil are disclosed. The invention is especially applicable for mobile electronic devices having a motor and requiring a DC-to-DC conversion. By using the coil of the motor for DC-to-DC conversion and for the purpose of a motor no space for an additional coil is required. For motor control an H-bridge arrangement is provided allowing motor movement in both directions, to brake and free run. By adding two diodes and a capacitor and modulation of a switch of the H-bridge a DC-to-DC conversion has been made possible.
