The most common switching-power topology is a buck converter, which efficiently transforms high voltages to low voltages. Figure 1 shows a typical buck converter in which the N-channel MOSFET, Q 1, ...

Modern power delivery systems with DSPs, FPGAs and CPUs run on lower supply voltages and consume higher current. In fact, sub-1 V voltages are everywhere now. Meanwhile, intermediate bus voltages have ...

Intersil has announced the Endura ISL6522B single-phase, dual-mode, synchronous-buck PWM controller/driver IC designed to provide soft-start to power sensitive circuits and to handle pre-biased loads.

Managing medium- to high-current POL buck converters, the IR3622MPbF and IR3622AMPbF dual-phase PWM control ICs can be configured to support a single output in current-share mode, delivering up to 80A ...

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 ...

The IR3621M and IR3621F from International Rectifier are voltage-mode, dual-output bi-phase synchronous buck controller-driver ICs for high performance point-of-load (POL) buck converters used in ...

The first thing I ever built without a kit was a 5 V regulated power supply using the old LM309K. That’s a classic linear regulator like a 7805. While they are simple, they waste a lot of energy as ...

Buck-Boost DC-DC Converters are versatile power electronic devices that facilitate the conversion of a direct current (DC) input to a DC output that may be either higher or lower than the supply ...

Flyback converter technology remains pivotal in modern power electronics, offering a versatile solution for a broad range of applications from consumer electronics to industrial power supplies. Recent ...
