| NON-ISOLATED DC/DC CONVERTERS 3.0 Vdc - 5.5 Vdc Input, -5 Vdc/1 A, -5.2 Vdc/1 A, -12 Vdc/0.5 A Outputs xRAH-01FxxN Series * * * * * Non-Isolated Fixed Frequency High Efficiency High Power Density RoHS Compliant * * * * Low Cost Rev.A Excellent Thermal Performance OCP/SCP Industrial Temperature Range UL60950-1 Recognized (UL/cUL) Description The Bel xRAH-01FxxN modules are non-isolated; step down dc/dc converters that operate from a 3 V - 5.5 V source. Output voltages are -5.0 V, -5.2 V, and -12 V. They are packaged in a compact, overmolded package rated at 1 A, 1 A, 0.5 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 is typically 88% at 1 A, -5 V output at full load. Part Selection Output Voltage -5.0 V -5.2 V -12 V Input Voltage 3.0 V - 5.5 V 3.0 V - 5.5 V 3.0 V - 5.5 V Max. Output Current 1A 1A 0.5 A Max.
