With power densities of up to 1,032 W/in3, these devices offer an option for directly driving loads that require tightly regulated output voltages. Vicor’s current family of DCMs in a ChiP package offers up to ±3% regulation and can also be paralleled into arrays for higher power delivery.
The ChiP DCM can operate from a wide-range unregulated input to generate an isolated DC output. With its high frequency zero-voltage switching (ZVS) topology, the DCM converter delivers high efficiency across its entire input voltage range.
This series of DCMs are initially offered with 28V, 270V, and 275V nominal input voltages. These products are aimed at a variety of defence and industrial applications that require tighter output voltage regulation – these include, UAV, ground vehicle, radar, transportation and industrial controls. All these families are available in M-Grade, which provides operation down to -55°C.
The converters are part of Vicor’s Power Component Design Methodology; the added parts with enhanced output voltage regulation are shown in the table;
