TDK Corporation announces the addition of the TDK-Lambda brand i6A4W single inline package (SIP) to the i6A series of 250W rated non-isolated DC-DC converters.  Requiring less than 3cm2 (0.47in2) of printed board area, this provides a saving of 60 per cent over the i6A 1/16th brick package.

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 per cent. This allows operation in ambient temperatures of -40 to +125 degrees Celsius, with the minimised output derating, even in low airflow and high ambient temperature conditions. The product’s optimised dynamic voltage response reduces the need for external capacitors, saving cost and additional board space.

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.
