In summary, the integration of a high performance Zero-Voltage Switching (ZVS) topology within the PI33xx series of Cool-Power ZVS buck regulators enhances point of load performance, providing optimal efficiency for wide Vin operation. The ZVS topology enables high power density, and high-frequency operation that maximizes efficiency by minimizing the significant switching losses associated with conventional hard-switching buck regulators. The PI33xx series can support high performance conversions with large step down ratios up to the rated input voltage of 36V enabling system designers to deploy more efficient power distribution schemes that rely on a higher input voltage source. All products in the PI33xx series are highly integrated with control circuitry, power semiconductors and support components in a high density 10mm x 14mm x 2.56mm LGA System in Package (SiP). Power delivery can be further increased by interleaving multiple Cool-Power ZVS buck regulators using single wire current sharing without the need for any additional components. Cool-Power ZVS series buck regulators require only an external inductor and minimal ceramic capacitors for input and output filtering to form a complete high performance regulator. No frequency compensation, parametric settings or incremental external components are required.
