Japan, July 14 -- NISSHINBO MICRO DEVICES INC has got intellectual property rights for 'POWER SUPPLY DEVICE.' Other related details are as follows:
Application Number: JP,2022-134845
Category (FI): G05F1/56,310@A,H02M3/155@H
Stage: PROBLEM TO BE SOLVED: To make a power supply device operate by applying a heat to a load in order to make the load being stable with a simple structure under a low temperature.SOLUTION: A power supply device comprises: a high-side transistor to which a drain and a source are connected to between a power supply terminal and a middle point terminal; a low-side transistor to which the drain and the source are connected to between the middle point terminal and a ground terminal; a low-pass filter that outputs an output voltage by smoothing a voltage of the middle point terminal; a switching control part that makes the high-side transistor and the low-side transistor switch operate complementary; a liner control part that makes the high-side transistor operates in a liner amplification; a temperature detection element that detects the temperature of the load; and a temperature control part that controls a voltage value of an output voltage so as to set to a target value by the liner control part in the case where the temperature of the load is lower than a first value, and controls the output voltage so as to set to a target value by the switching control part in the case where a temperature of the load is higher than a second value.SELECTED DRAWING: Figure 1 (Grant)
