Drive to standardise sixteenth-brick convertors
Celestica is working with Cherokee International to drive the standardisation of a new sixteenth-brick DC/DC convertor footprint.
With a wide input voltage range of 36-55V, the HUS42-096 achieves high efficiency levels up to 97%.
Designed to address higher power needs than existing quarter-brick products, Celestica's HUS42-096 is rated at 460W and maintains the efficiencies, power density, and low cost that have made IBC convertors a popular choice for OEMs.
In an industry standard half-brick outline, the HUS42-096 is available in both positive and negative enable logic models, and can be used in parallel for an even higher output power.
With dimensions of 58 x 61 x 11mm, the HUS42-096 has a power density of 11.3W/cm3.
Celestica has also launched the QUS20-120-NVDR, the vertical mount version of the QUS20-120 IBC Series product line.
For applications where board space is scarce, this vertically mounted 4:1 fixed ratio quarter-brick only takes up 697mm2 of board space while achieving the leading efficiency and current thermal derating of the QUS20-120 Series convertors.
With dimensions of 64 x 10 x 32mm, the QUS20-120 convertors boasts high efficiency levels up to 96% and is available in both positive and negative enable logic models.
These convertors can also be used in parallel for higher output power requirements, providing added flexibility for the OEM system designer.
"As intermediate bus architecture continues to gain momentum in the marketplace, system designers are requiring power solutions that increase their flexibility and minimise risk", said Kulbir Dhillon, Director, Business Development, Celestica Power Systems.
"Celestica's goal is to offer one of the broadest selections of intermediate bus convertors with multiple form factors, input/output voltage ratios and optimal solutions to meet our customer's needs".
Celestica's QUS20-120-NVDR and HUS42-096 are available now.
Pricing at 1000 units ranges from US $39.00 to $78.00 based on model and output voltage.
