Our existing Cool-Power 48V ZVS 20A Buck Regulator portfolio offers 48V direct-to-PoL conversion without compromising on efficiency or power density. To accommodate the demand for higher powers in many applications including lighting, communications, automotive equipment, and datacenter, we announced today the PI3523-00-LGIZ (PI3523), a 48 VIN, 3.3 VOUT nominal Buck Regulator capable of supplying up to 22A.

Like all Cool-Power ZVS Regulators this new component is designed to be easy to use while delivering high power density and high efficiency. The new component extends the PI352x family of 48V input, 20A solutions that span 2.2V – 14V, and complements the previously released 10A 48 VIN PI354x family, enabling scalable power options for 48V direct to point-of-load (PoL) applications. The PI352x portfolio extends performance by delivering twice the power of the PI354x regulators using only a 40% larger package, while retaining all features of the lower-power family.

PI352x regulators can easily support higher current loads as they can be paralleled with minimal external components. The new ZVS Regulators help ensure first pass design success with best-in-class performance.
