The iAH series of 40A Point of Load (POL) non-isolated DC-DC converters from TDK Corporation measure 10.2mm high with a 33mm x 13.5mm footprint. The iAH demonstrates an increase in output current of 100% compared to TDK-Lambda’s similarly sized iAF series. The iAH series is suited for a number of applications including datacom, telecom, industrial, broadcast and test and measurement equipment.

The 96% efficient converters can be adjusted across a 0.7V to 5.5V output range and deliver up to 150W. An input range of 3V to 17V enables the iAH to operate from either a 5V or 12V DC bus voltage - thus reducing inventory costs by stocking one part number. A weight of just 12g allows these surface mountable converters to be easily pick-and-placed using automated, high volume production equipment. As with all TDK-Lambda’s DOSA compatible footprint POLs, the iAH does not need externally mounted loop tuning components.

Standard features include a trim pin for output voltage adjustment, positive remote sense, remote on-off (positive or negative logic), input under voltage, over current and over temperature protection. A Power Good (low on fail) signal provides indication that the output outside of the ±12% set point tolerance, due to input under voltage, overload, over temperature or loss of control conditions.

Safety certification includes IEC/EN 60950-1, UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives.
