1 / 30 page  Cool-Power® Rev 1.3 vicorpower.com Page 1 of 30 12/2015 800 927.9474 8 V to 18 Vin, 15 A Cool-Power ZVS Buck Regulator Cool-Power® PI34xx-00 Product Description The PI34xx-00 is a family of high efficiency DC-DC ZVS-Buck regulators integrating the controller, power switches and support components within a high density System-in-Package (SiP). The PI34xx-00 is designed to achieve optimum efficiency at low input voltage ranges (8 V to 18 V). The utilization of zero current soft turn-on provided by the high performance ZVS topology within the PI34xx-00 series increases point of load performance, providing best in class power efficiency with high throughput power. The PI34xx-00 requires only an external inductor and minimal capacitors to form a complete DC-DC switching mode buck regulator. The ZVS architecture enables high frequency operation while minimizing switching losses and maximizing efficiency. The high switching frequency operation reduces the size of the external filtering components, improves power density, and enables very fast dynamic response to line and load transients. The ZVS architecture enables operation up to 750 kHz while minimizing switching losses and the use of variable frequency extends high efficiency over a very wide dynamic range. The PI34xx-00 series has a minimum on time of 20ns which enables large step down conversion ratios.
