TDK-Lambda: new 300W buck-boost DC-DC converter

Posted 2 April 2021

TDK Corporation announces the introduction of 20A 300W rated models to the TDK Lambda brand i7C series of non-isolated DC-DC converters.

The output voltage of these latest step-up and step-down converters is adjustable from 8 to 24V, and they are optimised to operate from a wide range input voltage of 9 to 36V. The converters seamlessly transition from buck to boost mode operation without disruption in performance.

The i7C2W 20A models can derive additional high power outputs from 12V or 24Vdc power supplies or batteries.

These very compact products are ideal for medical, industrial, automated guided vehicles, drones, and portable battery-powered equipment.

During light load conditions, the i7C’s control circuitry significantly reduces power consumption. At zero load, the input current draw is typically just 5mA, which can be reduced to around 0.25mA when the remote on-off puts the converter into standby. The low quiescent current allows battery-powered equipment to remain functional longer during periods of non-operation.

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.
