12A PoL DC-DCs with wide Vout range

January 12, 2016 // By Graham Prophet
TDK’s iCH series of 12A point of load (POL) non-isolated DC-DC converters can deliver 0.7V to 8.5V output adjustment range. Operating from a 4.5V to 14 VDC input, the products can operate from either a 5 V or 12 Vdc 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 converters achieve up to 97% efficiency minimising internal heating, 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.
