PI33XX-X1
8V to 36Vin, 15A Cool-Power ZVS Buck Regulator
Description
The PI33XX-X1 is a family of high efficiency, wide
input range DC-DC ZVS-Buck regulators integrating
controller, power switches, and support components
all within a high density System-in-Package (SiP). The
integration of a high performance Zero-Voltage
Switching (ZVS) topology, within the PI33XX-X1 series,
increases point of load performance providing best in
class power efficiency. The PI33XX-X1 requires only
an external inductor and minimal capacitors to form a
complete DC-DC switching mode buck regulator.

The ZVS architecture also 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 PI33XX-X1 series sustains high
switching frequency all the way up to the rated input
voltage without sacrificing efficiency and, with its
20ns minimum on-time, supports large step down
conversions up to 36Vin.
