TDK Corporation (TSE 6762) announces the addition of the TDK-Lambda brand i6A4W SIP (Single Inline Package) to the popular i6A series of 250W rated non-isolated DC-DC converters.  Requiring less than 3cm2 (0.47in2) of board area, this provides a saving of 60% over the i6A 1/16th brick package.

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.
 
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%.  This allows operation in ambient temperatures of -40°C to +125°C 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.
 
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.  Power good, operating frequency synchronisation and output sequencing are available as options.
 
Safety certification includes IEC/EN 60950-1, UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS Directives.  All i6A converters have a three-year warranty.
