Low-profile point-of-load DC outputs 40A

January 18, 2017 // By Graham Prophet
TDK-Lambda’s iAH series of 40A point of load (PoL) non-isolated DC-DC converters measures 10.2 mm high with a 33 x 13.5 mm footprint. 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 12Vdc bus voltage, reducing inventory costs by stocking one part number. A weight of 12g allows these surface mountable converters to be pick-and-placed using automated, high volume production equipment. The iAH does not need externally mounted loop tuning components and has excellent transient response to load changes.


Standard features include a trim pin for output voltage adjustment, positive remote sense, remote on-off (positive or negative logic), input under-voltage, overcurrent 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.
