i3A Series Non-Isolated DC-DC Converters

TDK-Lambda's 100 W non-isolated step down converters provide wide range inputs and outputs

Image of TDK Lambda i3A Series Non-Isolated DC-DC ConvertersTDK Lambda's 100 W rated i3A series of non-isolated DC-DC converters is capable of operating from an input voltage of 9 V to 53 V. The step-down converter delivers an output voltage that can be adjustable from 3.3 V to 16.5 V or 5 V to 30 V with output currents of up to 8 A. The series is designed to be used in a wide range of applications including medical, communications, industrial, and test and measurement equipment.

In a 1/32nd brick form factor measuring 19.1 mm x 23.4 mm x 9.6 mm, the converters can be used in conjunction with a single output 12 V, 24 V, 36 V, or 48 V AC-DC power supply to generate multiple additional regulated outputs, with or without battery backup.

Operating efficiencies are up to 98%, minimizing power losses to allow the series to operate in harsh ambient temperatures of -40°C to +125°C even with low airflow conditions. The need for external output capacitance is reduced due to an optimized dynamic voltage response, thus reducing board space requirements.

The basic feature models include an output voltage adjustment pin, positive or negative logic remote on-off, remote sense, input undervoltage, overcurrent, and thermal protection. All models are certified to UL/CSA 60950-1, IEC/EN 60950-1, and carry the CE mark for the Low Voltage and RoHS2 Directives.
