Title:
LOAD DRIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/139435
Kind Code:
A1
Abstract:
The load driving device of the present embodiment comprises: a step-up converter for raising a voltage provided by a power supply and supplying same to a load unit, by comprising a first driving unit and a second driving unit, the first driving unit comprising an inductor and a first fly capacitor, and charging energy provided by the power supply, as the inductor and the first fly capacitor are connected in parallel in a first phase, and discharging the charged energy, as the inductor and the capacitor are connected in series in a second phase, and the second driving unit comprising a second fly capacitor for charging energy provided by the power supply in the second phase and discharging the energy charged in the second phase; and a current control unit for controlling a current provided to the load unit by detecting the current flowing in the load unit and controlling the step-up converter. Furthermore, according to the present embodiment, a load is driven and controlled at the same time, and, thus, the benefit of being able to reduce power consumption compared to conventional technology is provided.
