High-Current PSiP Power Beads – PGL6477/78 Series

The PGL6477 and PGL6478 series high-current, low DCR inductors from Pulse Electronics, a YAGEO Company, can be used in single-phase point of load (PoL) and multi-phase buck converters to power processors, memory modules, FPGAs, and ASICS in servers, datacenters, networking systems, and graphics cards. Using Pulse Electronics, a YAGEO Company power bead technology, the PGL6477 and PGL6478 series are built with a single-turn copper frame which helps provide very low AC loss. The PGL6477 has a size of 6.45 mm × 6.45 mm; the PGL6478 has a low profile platform with a max height of 3.55 mm.

The PGL6477 and PGL6478 series inductors are designed with straddle construction, making them suitable for power supply in package (PSiP). The straddle terminals occupy a small pad layout area allowing more components to be put under the PSiP inductor, which helps reduce the power supply’s footprint. These series are built with automated production and are suitable for high-performance, high-reliability applications in data communications, computing, and industrial markets that require a price-competitive solution.
