250W Non-Isolated SIP DC-DC Converter Uses 60% Less PCB Area

250W Non-Isolated SIP DC-DC Converter Uses 60% Less PCB Area

TDK Corporation announces the introduction of 250W rated SIP (Single In-line Package) models to the TDK-Lambda i6A4W product family of non-isolated DC-DC converters. Utilizing less than 0.47 in2 of board area, this represents a 60% saving compared to 1/16th brick format converters.

Capable of operating from a wide input voltage of up to 9 to 53V, the i6A4W step-down converters deliver an output voltage that can be adjustable from 3.3V to 15V or 3.3V to 40V. The i6A4W series can operate from existing 12, 24, 36 or 48V system voltages to generate additional high power voltages in medical, communications, industrial and test and measurement equipment.

With efficiencies of up to 97.5%, power losses are minimized allowing the products to operate in harsh ambient temperatures of -40oC to +125oC even with low airflow requirements.  The need for external output capacitance is reduced due to an optimized dynamic voltage response, thus further 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.  The full-featured models are equipped with a power good signal, output voltage sequencing and the ability to synchronize the operating frequency to minimize system noise.  All models are certified to UL/CSA 60950-1, IEC/EN 60950-1 and carry the CE mark for the Low Voltage and RoHS Directives.
