High density DC-DC converter modules from Nu Horizons

These DC-DC converters have a footprint of just 16.26 x 16.26 mm, which is identical for all models (3A, 6A, 10A and 20A) so that designers have a convenient power migration path if system requirements change. Input voltage ratings range from 3.0 to 13.8 VDC (4.5V to 13.8 VDC for the 20A model), making the power converters compatible with a variety of input bus voltages. The power converters also feature a wide adjustable output range from 0.59 to 5.1 VDC through external resistor trimming, reducing the number of module types needed to support multiple applications.

The converters’ ultra-compact Land Grid Array (LGA) packaging enables a uniform, low profile (3.2mm typical) form factor, making them ideal for power applications where board space, airflow and height dimensions are critical. They can be mounted on either side of a circuit board for flexible space management and are fully compatible with automated circuit board assembly processes. The packaging’s design also offers designers an opportunity to employ a variety of conductive cooling techniques (heatsinks, coldplates, etc) via either surface.

The LGA C series offers high efficiency (92% typical at full load) under standard operating conditions and accommodates a wide range (-40 to +85 ºC) of ambient operating temperatures. The power converters are also fully equipped with a variety of best-in-class features – including under-voltage lockout, differential remote sense, output margining and short-circuit protection.
