High-output DC/DC converters

Improved power conversion allows the Typhoon 7.7 mm high quarter-brick modules to deliver up to 100A at 1.2V. The LQS100A48-1V2 provides 84.5% efficiency at full load. The company also offers the LQS80A48-1V8, which delivers 80A at 1.8V with 89.7% efficiency from a similarly-sized board. The modules operate from a standard 48V-input supply — over the full 36 to 75 VDC input voltage range — and offer an output voltage that is adjustable from 110% to 80% of nominal value. The converters feature short circuit, over-voltage and thermal protection, and are built with single-board, open frame construction with a thermally-enhanced double-power-pin footprint — the new industry standard. These converters require no heatsink and have no minimum load requirement.

Ferrite cores

ER planar cores meet demands for lower profile design, higher power design density and higher output currents. The Series ER 18, ER 23 and ER 25 are offered in three different ferrite materials, depending on frequency, saturation and power dissipation requirements. The ER cores offer better EMC properties that ELP cores because part of the winding is shielded from the core.
