High performance converters are suitable for harsh environments

15 July 2016

TDK announces the introduction of the 12, 24 and 28V output HQA DC-DC converters, with additional output voltage models to be added in the coming months.

Packaged in a ruggedised quarter brick form factor, the encapsulated HQA120 models can deliver 120W output power and will operate over a 9V to 40V input range (50V for 1 second). These 89 percent efficient converters are suitable for use in COTS, communications and industrial equipment.

The HQA120 has been qualified using methods consistent with MIL-STD-883 & 202, and offers a two screening and operating temperature options. The M-Grade has functional testing in cold, hot and room ambient temperatures, and an extended 96 hour burn-in with ten-cycle temperature testing. The S-Grade has functional testing at room ambient temperature and a standard burn-in period. The full load operating temperature for the M-Grade is -55 to +115°C and -40 to +115°C for the S-Grade.

Two baseplate mounting versions are available. The flanged format measures 60.6 x 55.9 x 12.7mm, with the non-flanged following the standard quarter brick format and measuring 60.6 x 39 x 12.7mm. Negative logic remote on/off and remote sense is provided.

All models are fully regulated, have a constant switching frequency for easier system EMC integration and utilise no opto-couplers in the control loop for increased reliability. Full auto-recovery protection is provided and the output can be adjusted ±10 percent or turned on or off remotely.

Safety certification includes IEC/EN 60950-1, UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives. Input to output and input to baseplate isolation is 2250Vdc.
