When designing a complete electronic system, one of the first challenges is to ensure a stable and reliable power supply for the entire circuit. The performance of the power module directly affects the overall stability and functionality of the system. While the 51-series microcontroller has been widely used for many years, it's known for being more sensitive to electrical noise and prone to program errors. To address this issue, it's essential to implement a robust power supply solution that ensures the microcontroller operates smoothly and reliably. This is especially important in modern applications where high performance and long-term stability are critical. In addition, using advanced components like the STM32L151CCU6 microcontroller, high-quality MOS power ICs, and precise inductors can significantly improve the system’s efficiency and reliability.
