New 1 W and 0.5 W-rated dc-dc converters extend appeal of modules in SOIC-16 package

RECOM R05C05TE05S and R05CT05S-R dc-dc converter modules are ideal for applications that operate in light-load mode. Manufacturers will also appreciate the converters’ low EMI and attractive cost.

RECOM has extended its range of dc-dc converters housed in a low-profile SOIC-16 package. 

The 0.5W-rated R05CT05S-R and 1W-rated R05CTE05S operate from an input-voltage range of 4.5 V to 5.5 V. The R05CT05S-R produces a post-regulated, selectable output of either 5 V or 3.3 V. The R05CTE05S produces a semi-regulated 5 V output. 

Line and load regulation figures are specified across the full operating-temperature range of -40°C to 125°C for the R05CTE05S, and -40°C to 140°C for the R05CT05S-R. There is no minimum load requirement, making the parts ideal for applications that operate in light-load mode.

The R05CTE05S has a basic insulation rating of 3 kV ac/1 minute, and provides more than 8 mm of input/output creepage and clearance. Isolation capacitance is just 7 pF. The R05CT05S-R offers reinforced isolation of 5 kV ac/1 minute with a 2 MOPP rating for medical applications.

EMI outputs are particularly low compared to more expensive competing dc-dc converters.

The SOIC-16 package has a footprint of just 10.4 mm x 7.5 mm and a 2.5 mm profile.  The R05CTE05S is partially pin-compatible with the R05CT05S, which includes extra features such as remote on/off.

RECOM also supplies a broad portfolio of dc-dc converter modules for higher input-voltage ranges. The RPMGQ-20 and RPMGS-20 are open-frame, non-isolated dc-dc buck converters operating from an 18 V to 75 V input range. They produce optional nominal outputs of 5 V trimmable over a wide range of 3.3 V to 8 V, or 12 V, trimmable between
8 V and 24 V. Rated output current for all variants is 20 A.
