SIP format non-isolated 250W DC-DC converter saves 60% PCB board area

Posted : 03 Oct 2019

TDK Corporation (TSE 6762) announces the addition of the <a href="https://www.emea.lambda.tdk.com/uk/products/product-details.aspx?scid=359">TDK-Lambda brand i6A4W SIP (Single Inline Package) to the popular i6A series of 250W rated non-isolated DC-DC converters</a>.&nbsp; Requiring less than 3cm2 (0.47in2) of board area, this provides a saving of 60% over the i6A 1/16th brick package.<br /> &nbsp;<br /> Offering adjustment ranges of up to 3.3V to 40V the 10 to 20A rated step-down converters can accept input voltages between 9 and 53V. The i6A4W series allows the creation of multiple, high current output voltages from a single output 12V, 24V, 36V or 48V AC-DC power supply, and is suitable for use in communications, industrial, test and measurement, broadcast and portable equipment.<br /> &nbsp;<br /> With overall dimensions of 33mm x 11.4mm x 24.8mm (L x W x H), these converters have ultra-high efficiencies of up to 97%.&nbsp; This allows operation in ambient temperatures of -40&deg;C to +125&deg;C with the minimised output derating, even in low airflow and high ambient temperature conditions.&nbsp; The product&rsquo;s optimised dynamic voltage response reduces the need for external &nbsp;&nbsp;&nbsp; capacitors, saving cost and additional board space.<br /> &nbsp;<br /> Standard features 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.&nbsp; Power good, operating frequency synchronisation and output sequencing are available as options.<br /> &nbsp;<br /> Safety certification includes IEC/EN 60950-1, UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS Directives.&nbsp; All i6A converters have a three-year warranty.
