ZVS Regulators PI33xx-0x 8 36V ZVS Buck Regulator Family IN Product Description Features & Benefits The PI33xx is a family of high-efficiency, wide-input-range DC -DC High-efficiency ZVS Buck topology ZVS Buck regulators integrating controller, power switches and Wide input voltage range of 8 36V support components all within a high-density System-in-Package (SiP). The integration of a high-performance Zero-Voltage Very-fast transient response Switching (ZVS) topology, within the PI33xx series, increases point- High-accuracy pre-trimmed output voltage of-load performance providing best-in-class power efficiency. The PI33xx requires only an external inductor and minimal capacitors to User-adjustable soft start & tracking form a complete DC-DC switching-mode Buck Regulator.

The Phase delay (interleaving multiple regulators) 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 series Applications sustains high switching frequency all the way up to the rated input voltage without sacrificing efficiency and, with its 20ns minimum High-Efficiency Systems on-time, supports large step-down conversions up to 36V .
