Vicor Corporation announced the expansion of its family of isolated, regulated DC-DC converter modules (DCMs) in ChiP packages, with a range of ±1% voltage regulation devices. With power densities of up to 1,032 W/in3, the new series will offer engineers the option of 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 consistently delivers high efficiency across its entire input voltage range.
The new series of DCMs are initially offered with 28V, 270V, and 275V nominal input voltages. These products are aimed at a variety of defense 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.
