| NON-ISOLATED DC/DC CONVERTERS 3.0 V-5.5 V Input 0.75 V-3.63 V/6 A Output xRPB-06F1Ax Series * * * * * * * Non-Isolated High Efficiency High Power Density Excellent Thermal Performance Low Cost Remote On/Off Remote Sense * * * * * * RoHS Compliant Under Voltage Lockout (UVLO) OCP/SCP Over Temperature Protection Wide Trim Range Power Good Output Signal Can Sink & Source Current Description The Bel xRPB-06F1Ax modules are a series of non-isolated high density open frame dc/dc converters that can deliver up to 6 A of output current with full load efficiency of 94% at 3.3 V output. These modules provide precisely regulated voltage programmable via external resistor from 0.75 V to 3.63 V over a wide range of input voltage (Vin=3.0 V-5.5 V). Standard features include remote On/Off, programmable output voltage, over current protection, over thermal shutdown and short circuit protection. Part Selection Output Voltage 0.75 V-3.63 V Input Voltage 3.0 V-5.5 V Max. Output Current 6A Max.
