In the+5 V to±12 V boost-buck power supply circuit with MSP430F5359 as the main controller,both soft-ware control and hardware control methods are employed.For software control,the chip enable terminal is connected to the main controller's I/O port.The power supply detection circuit samples the output voltage of the power supply chip and feeds it back to the main controller's analog-to-digital converter for data processing to control the power supply circuit's on/off state.For hardware control,a jumper switch is used to control the power supply circuit's on/off state.By utilizing both control methods,the issues of overcurrent and overvoltage damaging the subsequent circuitry due to certain influences in the power supply circuit are avoided.The design results closely match the theoretical analysis results.
