TDK-Lambda News

Lambda has unveiled a new 40W addition to its UX series of industry standard 2 x 1 sized DC-DC converters. The UX40 is ideally suited to distributed power architectures, either used on its own or as an extremely cost efficient solution when coupled with a point of load DC-DC converter. It is the perfect choice for a wide range of telecom, IT and industrial applications allowing designers to take full advantage of forced-air cooling to achieve higher output current over a wider temperature range.

The UX40 is highly efficient with an 89% rating at ambient temperature. Switching frequency is 265kHz. The UX40 has an operating input voltage of 48V nominal over a 36-75VDC range and has a single 3.3V output. With convection cooling the 3.3V UX40 provides a maximum output current of 7.5A up to 50°C. Applying forced-air cooling at the rate of 1.5m/s to the same device allows the designer to achieve a maximum output current of 12.0A right up to 70°C.

Standard features include output current limiting, output over-voltage protection, input under-voltage lockout and thermal protection. Options include output voltage adjustment via an external resistor. Two remote on/off options are available.

Because the new UX40 is manufactured at its world-class production facility in Ilfracombe, Lambda can offer low minimum order quantities, ideal for prototyping and pre-production designs. Samples can be delivered within one week of order and volume quantities can be supplied in under four weeks.

All versions of Lambda’s UX series of DC-DC converters are CE marked and UL, CSA and VDE compliant.
