TDK has introduced the iCH series of 12 A point-of-load (POL) non-isolated DC-DC converters, featuring a wide 0,7 V to 8,5 V output adjustment range. Covering the 4,5 V to 14 V input range, the products can operate from either a 5 V or 12 V bus voltage, avoiding the need to stock multiple part numbers.
Measuring just 12,2 x 12,2 x 8,5 mm and weighing 2,5 g, these compact converters are ideally suited for a wide range of applications, including communications, broadcast, industrial and test and measurement equipment. Up to 97% efficiency minimises internal heating, allowing full 12 A operation in natural convection and low airflow environments with ambient temperatures of up to 70°C. 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% setpoint tolerance. Safety certification includes IEC/EN 60950-1, UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives.
