| NON-ISOLATED DC/DC CONVERTERS 4.5 Vdc - 14 Vdc Input 0.75 Vdc - 3.63 Vdc/10 A Output VRBC-10E1Ax RoHS Compliant Rev.A Non-Isolated High Efficiency Fixed Frequency Remote Sense Low Cost Under-Voltage Lockout (UVLO) Over Temperature Shutdown Wide Input Wide trim OCP/SCP Remote On/Off Active Low/High (option) Industrial Temperature Range Description The Bel VRBC-10E1Ax is part of the non-isolate dc/dc power converter series. The modules use a SIP package. These converters are available in a range of output voltages from 0.75 Vdc to 3.63 Vdc over a wide range of input voltage (Vin = 4.5 Vdc - 14 Vdc). The efficiency is typically 94.3% at 3.3 Vdc output at 5.0 Vdc input at full load. Part Selection Output Voltage 0.75 V - 3.63 V Input Voltage 4.5 V -14 V Max. Output Current 10 A Max. Output Power 36.3 W Typical Efficiency 94.3% Model Number Active Low VRBC-10E1AL Model Number Active High VRBC-10E1A0 Notes: 1. Add "G" suffix at the end of the model number to indicate "Tray Packaging". 2. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.
