SB series sixteenth-brick DC-DC converters

The SB family of converter comes in an industry standard footprint 0.9" x 1.3" x 0.404" package. The 2:1 Vin series of converter operates over the input range of 9 to 18, 18 to 36 or 36 to 75VDC and provides up to 100 Watts of output power, while the 4:1 Vin series operates over the input voltage range of 9 to 36 or 18 to 75VDC and provides up to 50 Watts of output power. The SB family offer high efficiency up to 93%. Standard models come with isolation of 2250VDC (1590VAC RMS), but optional High Isolation of 2828VDC (2000VAC RMS) is available by adding suffix "I" to the part number.

Datel has introduced the SB family of converter with ultra-wide input voltage ranges and optional high isolation of 2828VDC.
