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.

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 buck converter has emerged as a critical element in modern power electronics, offering highly efficient voltage step‐down conversion for a wide array of applications. Recent advances have focused ...

The ISL78268 from Intersil is a 55V synchronous buck controller with 3A integrated high side and low side drivers. The device provides high step down efficiency for a variety of load currents, from ...

As electronics become more advanced, the need for efficient power management increases. One crucial element of power management is the DC-DC converter, which is a device that converts DC voltage from ...

Converter ICs include an integrated power MOSFET, whereas controller ICs employ external power MOSFETs. Both configurations are classified as regulators because they regulate the output voltage. A low ...
