Vicor Corp. announced the newest entries in its portfolio of isolated bus converter modules (BCMs®) based on the company's Converter housed in Package (ChiP) power component platform. Supplying up to 1.75 kW at 50 V with 98% peak efficiency and power density of 2750 W/in3, Vicor's new ChiP BCM fixed-ratio power converters deliver 5X the power density of competing solutions, further extending the company's power performance leadership in this product category.
Vicor has also introduced new digital telemetry and control capabilities for its ChiP BCM portfolio, available as an option for the new 1.75 kW modules and previously announced 1.2 kW modules. This PMBus™ compliant digital interface option gives system designers access to the ChiP BCM's internal controller, enabling digital communication with an array of ChiP BCMs via a single bus for control, configuration, monitoring and other telemetry functions.
Vicor's ChiP BCMs' power performance profile is made possible by the underlying ZCS/ZVS Sine Amplitude Converter™ topology. Operating at megahertz switching frequency, ChiP BCMs enable fast response time and low noise operation at industry leading efficiencies. High fixed frequency operation also simplifies and reduces the size of external filter designs, yielding additional cost savings and accelerating time to market.
The new ETSI and ITU compliant 1.75 kW modules support a nominal input voltage of 400 V and nominal output voltage of 50 V, with a K-factor of 1/8. Vicor's 1.2 kW and new 1.75 kW BCMs are offered in the 6123 package. Standard BCM features include bidirectional operation, under-over-voltage lockout, over-current, short circuit and over-temperature protection.
Vicor's 1.75 kW ChiP BCMs and 1.2 kW ChiP BCMs are available today - pricing for OEM quantities is $170.00 and $120.00 respectively. The digital telemetry and control options are priced separately.
