12A PoL DC-DCs adjust over 0.7V to 8.5V output

November 17, 2016 // By Graham Prophet
TDK’s iCH series are 12A Point of Load (POL) non-isolated DC-DC converters, with a 0.7V to 8.5V output adjustment range. Operating from a 4.5 VDC to 14 VDC, the products can operate from either a 5V or 12VDC bus voltage, avoiding the need to stock multiple part numbers.

Measuring 12.2 x 12.2 x 8.5 mm and weighing 2.5g, these compact converters specify up to 97% efficiency, allowing the full 12A operation in natural convection and low airflow environments with ambient temperatures of up to 70ºC. The iCH converters have excellent transient response characteristics, without the need for externally mounted loop tuning circuitry.


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 DC Good (low on fail) signal provides indication that the output is outside of the ±12% set point tolerance.


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