DC/DC Converters

 DC/DC Converters are part of CODICOs product range.

Choosing the Right DC/DC Converter

DC/DC converters are used in a wide variety of industrial (IEC/EN-UL-CSA62368-1) and medical applications (IEC/EN-UL-CSA60601-1 4th Edition). In addition to these two main groups, special certifications must be covered, such as, for instance IEC/EN50155 (EN50121-32, EN61373) for railway technology, which comprises EMC (EMI), ESD, surge, transients, and vibration and shock resistance, or also the household appliance standard IEC/EN-UL-CSA60335-1. The noise radiation IEC/EN55032 (CISPR22), Class A for industrial applications and Class B for end consumer devices in the commercial sector, is achieved by 5/6 – times shielded and earthed modules.

The key components of the DC/DC module must be ready for action 24/7, must resist thermal stresses, must carry safety approvals, and, above all, must be reliable. And for that reason, many manufacturers have now adopted the principle of a 10 year guarantee.

Galvanically Isolated DC/DC Converter

In addition to the standard footprints such as SIP 4,6,7,8, DIP14, 26, 24 and SMT(SMD) in the low-power range, industrial standards 1“x1“ and 1“x2“ are also steadily gaining in significance. The brick formats (Full, Half, ¼, 1/8, 1/16, 1/32) continue to be used in the Telecom sector.

The ever increasing power density has led to new cooling concepts: Apart from traditional cooling elements, which are now integrated into the housing itself, the dissipation of heat via the SMT pins/pads is also provided for, in particular in the POL area (LGA), or via contact surfaces for thermal contacting at the device housing.

Apart from the more traditional interface modules, with purely functional or basic isolation, a galvanically isolated DC/DC converter is a constituent part of the safety chain. Thereby, with medical applications the creepage and clearance required for the different overvoltage categories are only partially reached by the power unit. The type of isolation – doubled, reinforced – also plays a part in this, in particular with medical applications (MOOP – Means of Operator Protection, MOPP – Means of Patient Protection), in particular with classifications in accordance with NC(B), BF (body floating), CF (cardiac floating) with which the patient leakage separates the wheat from the chaff. In addition to electrical safety (LVD, ELV, SELV), which is required for obtaining the CE marking, the electromagnetic compatibility (EMC, EMI) also has a decisive role to play.
