Non-isolated buck or step-down DC/DC converters are needed as point-of-load (POL) regulators to power devices such as microprocessors, ASICs, FPGAs, and other semiconductor loads on system boards in telecom, datacom, and industrial applications. Due to recent advances in process technologies, packaging, and magnetics, buck converter solutions have been developed that deliver a complete power supply in a package (PSiP). Incorporating a switching controller, power MOSFETs, capacitors and magnetics in a single compact package, these integrated buck converters are raising the bar in power density and efficiency while offering the performance needed to meet the stringent power supply requirements of new-generation systems.
