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 fraction ...

Negative buck converters are increasingly used to “step down” (by absolute value) negative voltages. The main reason behind the increasing demand is the standardization of switching transformers, ...

Advanced Power Electronics Corp. has introduced the APE1723-HF-3, a 200kHz 1A PWM buck DC/DC convertor with an adjustable output voltage range from 0.745V to 24V. Advanced Power Electronics Corp. has ...

DC to DC conversion has come a long way. What was once took an electromechanical vibrator and transformer has been reduced to a PC board the size of a largish postage stamp that can be had for a ...
