SRAH-01KX50

NON-ISOLATED DC/DC CONVERTERS 9.0 Vdc - 18 Vdc Input 15 Vdc/0.8 A Output xRAH-01KX50 • • • Non-Isolated High Efficiency RoHS Compliant • • • Rev.A Low Profile Package Remote On/Off Active Low Fixed Frequency (500 kHz) Description The Bel xRAH-01KX50 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 of 15 Vdc output module is typically 87% at full load. Part Selection Output Voltage 15 V Input Voltage 9 V - 18 V Max. Output Current 0.8 A Max. Output Power 12 W Typical Efficiency 87% Part Number Surface Mount SRAH-01KX50 Part Number Vertical Mount VRAH-01KX50 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.
