Vicor BCM6123TD1E2663Txx fixed ratio DC-DC converter module

The Vicor BCM6123TD1E2663Txx is a high-density, high-efficiency, fixed ratio DC-DC converter module in a ChiP package, which operates from a 384 VDC nominal input and delivers an isolated and safety extra low voltage (SELV) 24 V secondary output.

The product is offered in a through-hole form factor measuring 61 x 23 x 7.26 mm.

Targeting industrial, telecom and lighting applications, high-voltage bus converters give system designers a simple and cost-effective means to create common bus voltages of 12, 24 and 48 V directly from 384 VDC.

Based on the patented Sine-Amplitude Converter topology, high-voltage ChiPs are able to reach peak efficiencies of 98% and achieve power densities up to 2400 W/in³. These flexible modules can be easily paralleled into high power arrays and outputs can be put in series to achieve higher VOUT. In addition, the high-voltage BCMs are offered with either analog or digital signal interface and all 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 utilising the sine-amplitude converter’s low AC impedance relative to the down-stream regulator, effectively ‘reflecting’ the capacitance across the module.

With the K=1/16 model, 500 µF of 24 V point-of-load capacitance can be effectively provided by 2 µF on the module’s primary side.
