New converters in the i7C series

Posted 13 October 2020

TDK-Lambda announces the introduction of 12.5A 300W rated models to the i7C  series of non-isolated DC-DC converters. The output voltage of these step-up and step-down converters can be adjusted from 5 to 28V and they accept a wide range input voltage of 9 to 53V.

The i7C 12.5A series can be used to derive additional high power outputs from a 12V, 24V, 36V or 48V DC power supply.

These very compact products are suited for use in medical, communications, industrial, test and measurement, broadcast and portable battery powered equipment.

At zero load, the input current draw is typically just 5mA, which can be reduced to around 0.25mA when the remote on-off is used to put the converter into standby.

Three mechanical configurations are available, measuring 36.8mm wide and 34mm in length.

The thermal design of the i7C series allows for minimal output de-rating, even with low airflow conditions.

Standard features for the i7C series include a trim pin for output voltage adjustment, + remote sense, remote on-off (positive or negative logic), input under-voltage, over-current and over-temperature protection.

As an option, the full-featured models are equipped with a power good signal, output current monitoring and to minimise system noise, the switching frequency can be synchronised to another model or to an external clock.

All models have safety certification to the IEC/EN 62368-1 and 60950-1 standards.
