Packaged in a ruggedised quarter brick form factor, the encapsulated HQA120 models from TDK can deliver 120 W output power and will operate over a 9 V to 40 V input range (50 V for 1 second). Available with 12 V, 24 V or 28 V outputs, these 89% 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 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 10-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°C to +115°C and -40°C to +115°C for the S-Grade.
Two baseplate mounting versions are available. The flanged format measures 60,6 x 55,9 x 12,7 mm, with the non-flanged following the standard quarter brick format and measuring 60,6 x 39 x 12,7 mm. Negative logic remote on/off and remote sense are provided.
All models are fully regulated, have a constant switching frequency for easier system EMC integration, and utilise no optocouplers in the control loop for increased reliability. Full auto-recovery protection is provided and the output can be adjusted ±10% or turned on or off remotely.
