2 W and 3 W DC-DC converters

1 December 2019 Power Electronics / Power Management

Recom has extended its range of unregulated DC-DC converters with the RHV2 and RHV3 series which feature ultra-high isolation ratings of 12,5 kV a.c./one minute or 20 kV d.c./one second, in a compact SIP16 package that measures just 45 x 15 x 17 mm. With more than 30 mm input-to-output pin separation, the converters are certified to IEC/EN 62368 and IEC/EN 61010 for 12,5 kV a.c. reinforced isolation up to 5000 m altitude.

The RHV2 provides 2 W up to 85°C and the RHV3 up to 3 W at 80°C without load derating. Both series have nominal 5, 12 or 24 V inputs and a choice of 5, 12, 24 single or +/- 5 or +/-12 V dual outputs. Efficiency is up to 81,5%, isolation capacitance is very low at 4 pF typical and the parts comply with EN 55032 (class B) EMI limits with a simple external LC input filter. Reliability is very high with MTBF at 14,6 million hours for the RHV2 series at 25°C (13,4 million hours for RHV3).
