i7C DC/DC Converters

TDK-Lambda’s wide-input buck-boost DC/DC converters have an adjustment range of 9.6 V to 48 V

Image of TDK Lambda i7C DC/DC ConvertersTDK-Lambda's 300 W, 8 A rated i7C non-isolated DC/DC converters have an input range of 9 VDC to 53 VDC, with an output that can be adjusted from 9.6 V to 48 V. The product's topology enables a seamless transition from buck (voltage reduction) to boost (voltage increase) operation. The i7C is ideal for generating additional high-power outputs, from existing 12 V, 24 V, 36 V, or 48 V system voltages, in medical, communications, industrial, test and measurement, and battery-powered equipment.

With efficiencies of up to 97%, power losses are minimized allowing the product to operate and deliver high useable power in demanding thermal environments. Under light load conditions, the i7C's control techniques significantly reduce power dissipation. A 5 mA input current draw is typical under zero load conditions. This can be reduced to typically 0.25 mA when the remote on/off is utilized to place the unit in standby mode. This extends the amount of time battery-powered equipment can remain functional during periods of non-peak operation.

The basic feature models include an output voltage adjustment pin, positive or negative logic remote on/off, positive remote sense, plus input undervoltage, overcurrent, and thermal protection. The full-featured models are equipped with a power good signal, output current monitoring, and the ability to synchronize the operating frequency to minimize system noise.

The i7C converters measure 34 mm x 36.8 mm and follow the industry standard 1/16th brick pin-out. Three mechanical configurations are available: a low 12.2 mm high open-frame model, a baseplate construction for conduction cooling, or with an integral heat sink for convection or forced air-cooled environments. The i7C's design reduces the number of external components, saving both cost and board space.

All models are certified IEC/UL/EN 62368-1 and 60950-1 and carry the CE mark for the low-voltage and RoHS directives.
