12.5-amp 300-Watt DC-DC converters to power communications and industrial applications introduced by TDK

Sept. 10, 2020
With an input range of 9 to 53 volts DC, users can adjust the output from 5 to 28 volts, and switch from voltage reduction to voltage increase operation.

SAN DIEGO – TDK-Lambda Americas Inc. in San Diego is introducing additional 12.5-amp 300-Watt rated models to the company's i7C non-isolated DC-DC converters for communications, industrial, test-and-measurement, and battery-powered applications.

With an input range of 9 to 53 volts DC, users can adjust the output from 5 to 28 volts. The i7C topology enables users to switch from buck (voltage reduction) to boost (voltage increase) operation.

The series is for generating additional high power outputs, from existing 12-, 24-, 36-, or 48-volt systems. Efficiencies to 96 percent help minimize power losses in communications and related applications.

Under light loads, the i7C's control techniques reduce power dissipation. A 5 milliamps input current draw is typical under zero load conditions. This can be reduced to typically 0.25 milliamps with the remote on-off is in standby mode.

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

All the i7C converters measure 34 by 36.8 millimeters and follow the industry standard 1/16th brick pinout. Three mechanical configurations are available: a low 12.2-millimeter high open frame model, a baseplate construction for conduction cooling, or with an integral heat sink for convection or forced-air cooling.
