PI33xx-x0
8 V to 36 Vin Cool-Power ZVS Buck Regulator Family
Product Description
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 20
ns minimum on-time, supports large step down conversions up to
36 Vin.
