Cool-Power®
ZVS Switching Regulators
PI33xx-x0
8V to 36VIN Cool-Power ZVS Buck Regulator Family
Product Description
Features & Benefits
The PI33xx-x0 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-x0
series, increases point of load performance providing best in class
power efficiency. The PI33xx-x0 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-x0 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.
Applications
• High efficiency systems
• High voltage battery operation
