User-configurable power regulator modules

March 20, 2013 // By Graham Prophet
Vicor has announced a series of user-defined, high-performance VI Chip PRM modules that customers can configure and simulate with the PowerBench online tool suite; the 48-V VI Chip PRM modules are intended for PoL buck-boost or factorised power applications.

The PowerBench online tool suite gives designers the flexibility to specify the voltage, current and protection parameters of their PRM module and immediately simulate their models in application-specific operating conditions.

Incorporating Vicor’s high-frequency ZVS buck-boost technology, customer-configurable VI Chip PRM modules can deliver up to 500W at over 97% efficiency, at power densities of up to 1,700 W/in 3 (103 W/cm 3). Models are available in both full-chip and half-chip packages with input voltage ranges of both 36 - 75 V and 38 - 55 V, and, when used as a PoL buck-boost regulator, provides a user-defined output between 26 V and 52 V. When used with VI Chip VTM current multiplier modules, PRMs efficiently support output voltages from 0.5 V to 55 Vdc.

The online PowerBench tools afford designers a fast and efficient pathway to customising

VI Chip PRM modules to meet their exacting requirements for high-power applications. Data sheets, part numbers and pricing information are provided for designers’ uniquely-configured devices, and devices are shipped to customers within 5 business days.

Vicor’s online configuration tool for its VI Chip PRM modules is available for use today via Vicor’s PowerBench online design centre,at
