Isolated 384V to 12V, 300W bus converter

The 12 V (nominal) output can be paralleled for high current outputs or connected in series to create a 48V bus, making the converter ideal for use in high performance server and telecom AC-DC SMPS and enabling major power density improvements in the post-PFC DC-DC stage. The BCM converter may also be used in high-power, high-efficiency data center applications to power individual cards or blades directly from the HV distribution bus.

The V•I Chip package ― measuring just 32.5 x 22 x 6.6 mm ― is compatible with standard pick-and-place surface-mount machinery and assembly processes. It provides flexible thermal management through its low junction-to-case and junction-to-board thermal resistance. The low impedance of the BCM converter enables POL capacitance minimization or elimination while the positive temperature coefficient of the output means that converters share simply and reliably with no interconnect circuitry; all resulting in savings of board area, materials, and total system cost.

New 1.2 kW demo boards are now available to enable designers to experience the high performance and flexibility of the 300 W BCM converters in many application systems.

The Bus Converter Module B384F120T30 is priced at $37.50 in OEM quantities (FOB Andover, USA), and is available immediately from stock. Single 300 W BCM evaluation boards and two new 1.2 kW demo boards (12 V, 100 A or 48 V, 25 A outputs) are also available from stock and priced at $99 (FOB Andover, USA) for the single BCM board and $399 (FOB Andover, USA) each for the 1.2kW demo boards.
