Expanded HV converter family offers 384 to 24Vdc module in a ChiP package

The new BCM6123TD1E2663Txx is a high-density, high-efficiency, fixed ratio dc/dc converter module in a ChiP (Converter housed in Package) device, which operates from a 384 Vdc nominal input and delivers an isolated and Safety Extra Low Voltage (SELV) 24V secondary output. The new BCM 6123 ChiP  is offered in a through-hole form factor measuring 61 x 23 x 7.26 mm.


The BCM6123TD1E2663Txx expands the family of high voltage bus converters to include K=1/8 (384 – 48 VNOM), K=1/32 (384 – 12 VNOM), and the new K=1/16 (384 – 24 VNOM) modules. The Vicor BCMs are fixed ratio power converters, meaning that they convert any input voltage within a specified input range to an output voltage equal to the input voltage divided by the BCM’s transformation ratio, or K-factor. The converters target industrial, telecom, and lighting applications, by creating common bus voltages of 12, 24, and 48 V directly from 384 Vdc.


Based on the patented sine-amplitude converter topology, the devices reach peak efficiencies of 98% and achieve power densities up to 2,400 W/in³. The modules can be paralleled into high power arrays and outputs can be put in series to achieve higher VOUT. Additionally, the high voltage BCMs are offered with either an analog or digital signal interface and have an operating temperature range of -40˚ to +100˚C.


High voltage BCMs allow designers to reduce the amount of bulk capacitance needed at the load by using the sine-amplitude converter’s low AC impedance relative to the down-stream regulator, effectively ‘reflecting’ the capacitance across the module. With the new K=1/16 module, 500 µF of 24 V point-of-load capacitance can be effectively provided by 2 µF on the module’s primary side.
