The PG2290, PGL6395, and PA5615 series portfolios of high current, low DCR inductors from Pulse Electronics, a YAGEO Company, are used in single-phase PoL and multi-phase buck converters to power processors, memory modules, FPGAs, and ASICS in servers, datacenters, networking systems, and graphics cards. These three families provide lower core loss using the latest high-frequency materials, reduced DCR, and higher current ratings in different footprints, with the thinnest only 4.6 mm (max) and 140 A Isat (max). These multi-phase buck topologies distribute the current among multiple parallel paths with staggered turn-off and turn-on. By operating each phase in a staggered fashion, the ripple currents in each phase tend to cancel at the output, and the overall ripple current seen at the load is much smaller than the ripple on each phase. This approach allows smaller inductances to be used (typically on the order of 70 nH to 320 nH) and can allow design engineers a trade-off between how quickly the converter responds to a change in the load current (transient response) versus the stability of the control loop. By adjusting the number of phases used in the converter, the designer has the flexibility to optimize the circuit for their specific application.
