End of Life ZVS Regulators PI33xx-x1 8 36V , 15A ZVS Buck Regulator IN Product Description Features & Benefits The PI33xxx 1 is a family of high efficiency, wide input range High-efficiency ZVS Buck topology DCDC ZVS Buck regulators integrating controller, power Wide input voltage range of 8 36V switches and support components all within a high density SysteminPackage (SiP). The integration of a high performance Very fast transient response ZeroV oltage Switching (ZVS) topology, within the PI33xxx 1 series High-accuracy pre-trimmed output voltage increases point of load performance providing best in class power efficiency. The PI33xxx 1 requires only an external inductor and User-adjustable soft start & tracking minimal capacitors to form a complete DC DC switching mode Buck Regulator.

Fault reporting The high switching frequency operation reduces the size of the Enable and SYNCI pin polarity external filtering components, improves power density, and Phase delay (interleaving multiple regulators) enables very fast dynamic response to line and load transients. The PI33xxx 1 series sustains high switching frequency all the Applications way up to the rated input voltage without sacrificing efficiency and, with its 20ns minimum on time, supports large step down High-Efficiency Systems conversions up to 36V . IN Computing, Communications, Industrial, Automotive Equipment High-Voltage Battery Operation Package Information 10 x 14 x 2.6mm LGA SiP a 2 I C functionality is now standard when purchased as PI330100 LGIZ.
