| NON-ISOLATED DC/DC CONVERTERS 9.0V-18V Input 5V/1A & 9V/1A & 12V/1A Output X7AH-01K Series * * * Non-Isolated High Efficiency Fixed Frequency (450kHz) * * * Low Profile Package Remote On/Off Active Low/High Description The Bel X7AH-01Kxx0 is part of the low cost non-isolated DC/DC converter series. The modules use a SMD or vertical package for ease of layout and space savings. The output is closely regulated and the efficiency of 12V output module is typically 87% at full load. Part Selection Output Voltage 5V 9V 12V Input Voltage 9V - 18V 9V - 18V 9V - 18V Max. Output Current 1A 1A 1A Max. Output Power 5W 9W 12W Typical Efficiency 81% 86% 87% Part Number Surface Mount S7AH-01K50x S7AH-01K90x S7AH-01KX2x Part Number Vertical Mount V7AH-01K50x V7AH-01K90x V7AH-01KX2x Note: Use "0" to replace "x" in the above part number to indicate Active High, and "L" to indicate Active Low. Add "0" suffix at the end of the model number to indicate "Tube Packaging", and "R" for "Reel Packaging", and "G" for "Tray Packaging".
