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 ...

This article provides an examination of the input capacitor requirement for single- and multiple-channel buck converter voltage regulators. The input capacitor of a buck converter is a critical power ...

The drive to increase efficiency and reduce the size of switching power supplies has proliferated into just about every aspect of industrial, consumer, and lighting electronics. The simple step-down ...

Power supply designers should be aware that all switchmode supplies are made up of buck or boost regulators (or combinations of buck/boost regulators) with or without dc transformers. An excellent ...

Power supplies for today's high-performance microprocessors require high-current, low-voltage dc-dc converters with fast transient responses. Such supplies must deliver currents of greater than 100 A ...
