| NON-ISOLATED DC/DC CONVERTERS 3.0V-5.5V Input -5V/1A & -12V/0.5A Output X7AH-01FXXN Series * * * * Non-Isolated Fixed Frequency High Efficiency High Power Density * * * * Low Cost Excellent Thermal Performance OCP/SCP Industrial Temperature Range Description The Bel X7AH-01FXXN modules are non-isolated, step down DC/DC converters that operate from a 3V-5.5V source. Output voltage are -5V,-12V. They are packaged in a compact, overmolded package rated at 1A, 0.5A. 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 is typically 88% at 1A, -5V output at full load. Part Selection Output Voltage -5V -12V Input Voltage 3.0V - 5.5V 3.0V - 5.5V Max. Output Current 1A 0.5A Max. Output Power 5W 6W Typical Efficiency 88% 88% Part Number Surface Mount S7AH-01F50N S7AH-01FX2N Part Number Vertical Mount V7AH-01F50N V7AH-01FX2N Note: Add "0" suffix at the end of the model number to indicate "Tube Packaging", and "R" for "Reel Packaging", and "G" for "Tray Packaging".
