In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed ...

He built a buck converter and ... to 0% efficiency because the circuit won’t work without it. If you want a refresher on how a buck converter — that is, a DC to DC converter that reduces ...

055UMC_DCDC_01 is high-efficiency step-down DC-DC switching buck converter targeted for operation from 2.0V to 3.6V input voltage. It is able to supply circuits with 1.2V and up to 50 mA average ...
