Is it better to first increase the voltage to 5V and then decrease it to 3.3V when using a 3.7V lithium battery? Or is it better to first decrease it to 3.3V and then increase it to 5V?: Recently, I have a project that requires peripherals with 5V and 3.3V. The main control is 3.3V, and there is a screen powered by 5V. The current is about 300+mA. The lithium battery is a single-cell ...; wangerxian Power technology
