The DC / DC converter circuit of the conventional synchronous rectification type switching regulator has a problem that the PWM frequency is distorted due to external factors such as overheating, and there is a problem that the circuit malfunctions because there is no overvoltage protector and overheat detection circuit of the input / output. Accordingly, the present invention applies the DC-DC converter shown in FIG.

In more detail, when the input voltage is input through the rechargeable battery, the filter 401 passes through the filter 401, and the overvoltage is removed by the input overvoltage protector 404, which is half-wave and full-wave input switching by the PWM controller 406. The voltage is then stepped up or down via the transformer 402.

The signal switched by the PWM frequency is switched by the FET device, and senses the current of the transformer 402 to input the PWM control signal. The signal boosted by the transformer 402 is filtered by the LC filter 403 which is a low frequency filter to become an output voltage. The output voltage terminal is provided with an overvoltage protector 405 to suppress the occurrence of overvoltage.

The PWM controller 406 is a PWM input frequency generating circuit for dividing the input voltage and is connected to the overheat protection circuit 407.

The overheat protection circuit 407 detects overheating in the DC / DC converter circuit of the synchronous rectifying switching regulator and transmits an overheat detection signal to the controller. In addition, the transformer 402 amplifies or drops the input voltage, and typically, the voltage is determined in proportion to the ratio of the number of turns on the primary side and the secondary side of the transformer 402. In addition, a current sensor 408 is provided to measure the current of the transformer 402, and the current sensor 408 is a current sensor using a Hall effect, a current sensor using a current loop, or the like. Current sensors can also be used.

When the current value of the current sensor 408 is greater than or equal to a predetermined voltage, the PWM control circuit 410 detects this and sends an overcurrent message, and cuts off the current if necessary. An AC voltage in a DC / DC converter circuit of a synchronous rectifying switching regulator normally uses a FET, and the FET is turned ON / OFF by applying a voltage to the gate terminal of the FET.

The LC filter 403 connected to the output voltage terminal is a low pass filter and is used to smooth the voltage. In addition, in an embodiment of the present invention, the PWM controller may remotely monitor the voltage abnormality by remotely transmitting a communication signal to the server 20.

The PWM controller 406 circuit is shown in FIG. 5, and the overheat protection circuit 407 is shown in FIG. 6. 7 is a PWM controller circuit, the PWM output frequency is determined by R3, C2, C34 of FIG. When the temperature of the PWM output temperature rises due to overheating of the DC / DC converter, frequency fluctuation occurs. To prevent this, the capacitance value is changed from a conventional tantalum capacitor to an MLCC capacitor whose capacitance is stable even with a temperature rise. Stability is increased to prevent frequency distortion caused by temperature.
