PI34xx-00
8 V to 18 Vin, 15 A Cool-Power ZVS Buck Regulator
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.
