WebApr 12, 2024 · As it is, the V1 on time is too long; watch inductor current in the first cycle. The converter is also operating in discontinuous mode despite a significant load, so the output voltage swing is huge. I'd say start design calculations as if this were a 36v buck converter, and then work in how much of the on-time can be shared by the 12v source. WebThe result of the LTSpice simulation satisfies the supply voltage for the servo. The 11.1V input voltage is stepped down to 5V. The current output reaches up to 1.2A at steady-state and is more than enough to power the servo at the wrist (+ hand servo). Hence, this buck converter can be used in our design for the PCB.
