Vicor has extended its family of isolated, regulated DC-DC converter modules (DCMs) in ChiP packages, with a range of ±1% voltage regulation devices. With unrivaled 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.
Supporting Point-of-Load Applications
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.
