These converters are available in a range of output voltages from 0.8 Vdc to 5.5 Vdc. It is packaged in a compact, overmolded package rated at 8 A. Optional lead forming provides a vertical mount product for minimal footprint or a surface mount option for a very low profile. The output is closely regulated and the efficiency for 5 Vdc output is typically 93% at full load. Part Selection Output Voltage Input Voltage Max. Output Current Max. Output Power Typical Efficiency Part Number Surface Mount Part Number Vertical Mount 0.8 V - 3.63 V 4.5 V - 14 V 8 A 26.4 W 91% SRAH-08E1A0 VRAH-08E1A0 4.5 V - 5.5 V 8 V - 14 V 8 A 44 W 93% SRAH-08E500 VRAH-08E500 Notes: 1. Add “0” suffix at the end of the model number to indicate “Tube Packaging”, and “R” for “Reel Packaging”, and “G” for “Tray Packaging”. 2. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.
