Compact 12A POL DC-DC converters have a wide 0.7V to 8.5V output adjustment range
veröffentlicht : 14 Jan 2016
TDK Corporation announces the introduction of the iCH series of 12A Point of Load (POL) non-isolated DC-DC converters, featuring a wide 0.7V to 8.5V output adjustment range. Operating from a 4.5Vdc to 14Vdc, the products can operate from either a 5V and 12Vdc bus voltage, avoiding the need to stock multiple part numbers.
Measuring just 12.2 x 12.2 x 8.5mm and weighing just 2.5g, 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 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.
