| NON-ISOLATED DC/DC CONVERTERS 9.0 Vdc - 18 Vdc Input -12 Vdc/1 A -15 Vdc/0.8 A Output xRAH-01KXxN Series * * * Non-Isolated High Efficiency Fixed Frequency (400 kHz) RoHS Compliant * * * Rev.A Low Profile Package Remote On/Off Active Low Description The Bel xRAH-01KXxN is part of the low cost non-isolated dc/dc converter series. The modules use a SMD or SIP package for ease of layout and space savings. The output is closely regulated and the efficiency is typically 87% at full load. Part Selection Output Voltage -12 Vdc -15 Vdc Input Voltage 9 Vdc - 18 Vdc 9 Vdc - 18 Vdc Max. Output Current 1.0 A 0.8 A Max. Output Power 12 W 12 W Typical Efficiency 87% 87% Part Number Surface Mount SRAH-01KX2N SRAH-01KX5N Part Number Vertical Mount VRAH-01KX2N VRAH-01KX5N 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.
