Title:
TERMINAL DEVICE
Document Type and Number:
Japanese Patent JP2017017988
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a terminal device which improves bad exothermic, efficiency, etc. when transmission power is made larger at the execution of non-contact power supply.SOLUTION: A terminal device 200 includes: a power reception unit which receives power transmitted in a non-contact manner from a power supply device 100; a rectification unit 203 which rectifies the reception power obtained in the power reception unit; a regulator 210 which converts the reception power after the rectification unit rectifies into the power of a predetermined voltage; a temperature sensor 207 which extracts a temperature; and a control unit 205 which controls the regulator on the basis of the temperature extracted by the temperature sensor. Based on the extracted temperature, the control unit determines which of a DC-DC converter 211 in the regulator and an LDO (Low Drop Out) 212 is to be used, to transmit an instruction to the regulator. Also, the control unit transmits a stop instruction to the regulator when determining that the temperature extracted by the temperature sensor unit is a predetermined temperature or greater.SELECTED DRAWING: Figure 1
