High-Isolation Sixteenth-Brick DC-DC Converters
Datel's SB Series (16th-brick) dc-dc converters feature ultra-wide input voltage ranges and offer an optional high-isolation (2828Vdc) in an industry-standard package. Tightly regulated outputs are available: 2.5V, 3.3V, 5V, 12V and 15V.
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-Vdc, 18- to 36-Vdc or 36- to 75-Vdc and provides up to 100 Watts of output power. The 4:1 Vin series operates over the input voltage range of 9- to 36-Vdc or 18- to 75-Vdc and provides up to 50 Watts of output power.
The SB family offer 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.
