Picor cool-power ZVS buck-boost diagram

The PI375x is a series of high efficiency, wide input range DC-DC ZVS-Buck-Boost regulators with VTM compatibility operation. The VTM compatibility operation allows the PI375x to act as a PRM and operate with a VTM Current Multiplier to form a Factorized Power Solution. The integration of a high performance Zero-Voltage Switching (ZVS) topology increases buck-boost regulator performance and provides best in class power efficiency and density.

The PI375x is a System-in-Package (SiP) module integrating a ZVS controller, power switches, and support components. The PI375x requires minimal external devices to form a complete DC-DC switching mode buck-boost regulator. The ZVS topology enables high frequency operation while minimizing switching losses and maximizing efficiency.  The ZVS topology, high frequency operation, efficiency, silicon integration, and power density are the combined elements that make the PI375x series recognized for high performance.
