300W 20A buck-boost DC-DC converter models are optimized for 24V input applications

March 18th, 2021

TDK Corporation (TSE 6762) announces the addition of 20A 300W rated models to the i7C non-isolated DC-DC converter series. These buck-boost board mount power modules have been optimized for 24V input with a range of 9 to 36Vdc and can be adjusted from 8 to 24V. The i7C topology enables a seamless transition from buck (voltage reduction) to boost (voltage increase) operation. The new models are ideal for generating additional high power outputs from 12 and 24V system voltages in medical, automated guided vehicles (AVG), drones, industrial, test, measurement and battery powered equipment.

Power losses are minimized with efficiencies up to 97%, 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 5mA input current draw is typical under zero load conditions and can be reduced to typically 0.25mA when the module is in standby mode using the output inhibit function. The low quiescent current allows battery powered equipment to remain functional longer during periods of non-operation.

The basic feature 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 are equipped with a power good signal, output current monitoring and the ability to synchronize the operating frequency to minimize system noise.

All the i7C2W converters measure 34mm x 36.8mm with a height of 14.7mm and follow the industry standard 1/16th brick pin-out. The i7C design reduces the number of external components, saving both cost and board space.

All models are certified to IEC/UL/CSA/EN 62368-1 and carry the CE mark for the Low Voltage and RoHS Directives.

More information on the 20A i7C2W models, including distributor inventory and evaluation boards, can be obtained from the TDK-Lambda Americas website at https://www.us.lambda.tdk.com.
