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

The 250-W rated angle In-line package (SIP)) models  of non-isolated DC-DC converters from TDK-Lambda I use less than 0.47 square inches of board space, a a 60% saving compared to 1/16th brick-format converters. It operates on 9 to 53V, and the down converters deliver an output voltage that can be adjusted from 3.3 to 15 V or 3.3 to 40 V. The i6A4W series can operate from existing 12, 24, 36 or 48-V 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 letting devices operate in temperatures from -40o to 125oC even with low airflow requirements. The need for external output capacitance is reduced due to an improved dynamic voltage response, thus further reducing board space requirements. The basic model features  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 can 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.
