TDK-Lambda i3A Series Non-Isolated DC-DC Converters come in 19.1 x 23.4 x 9.6mm size.

Press Release Summary:

TDK-Lambda i3A Series Non-Isolated DC-DC Converters are available in i3A4W008A033V and i3A4W005A150V variants. Units come with 9 to 53Vdc input and can be used with single output 12V, 24V, 36V or 48V AC-DC power supply. Products are suitable for medical, communications, industrial and test and measurement equipment applications. Converters offer output up to 100W or 8A and are operated in a temperature range of -40°C to +125°C. These devices meet UL/CSA 60950-1 and IEC/EN 60950-1 standards.


Original Press Release:

Wide Range Output, 1/32nd Footprint Converters Operate from a 9 to 53Vdc Input

TDK Corporation announces the introduction of the 100W rated TDK-Lambda i3A series of non-isolated DC-DC converters. Capable of operating from an input voltage of 9V to 53V, the step-down converter delivers an output voltage that can be adjustable from 3.3 to 16.5V or 5 to 30V with output currents of up to 8A. 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 x 23.4 x 9.6 mm, the converters can be used in conjunction with a single output 12V, 24V, 36V or 48V AC-DC power supply to generate multiple additional regulated outputs, with or without battery back-up.

Operating efficiencies are up to 98%, minimizing power losses to allow the series to operate in harsh ambient temperatures of -40oC to +125oC 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 under-voltage, over-current 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.
