NON-ISOLATED DC/DC CONVERTERS 4.5 Vdc - 13.8 Vdc Input 0.59 Vdc - 5.1 Vdc / 3 A Output VRAE-03E1AC      Non-Isolated High Efficiency Fixed Frequency Low Cost Wide Input RoHS Compliant     Rev.B Under-Voltage Lockout Wide Trim OCP/SCP Remote On/Off Description The Bel VRAE-03E1AC is part of the non-isolated dc/dc converter Power Module series. The modules use a SIP package. These converters are available in a range of output voltages from 0.59 Vdc to 5.1 Vdc over a wide range of input voltage (VIN = 4.5 Vdc - 13.8 Vdc).The efficiency is typically 91% at 3.3 Vout (Vin=12 Vdc) at full load. Part Selection Output Voltage 0.59 V - 5.1 V Input Voltage 4.5 V - 13.8 V Max. Output Current 3A Max. Output Power 15 W Typical Efficiency 91% Model Number Active High VRAE-03E1AC Notes: 1. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers. 2. Add “G” suffix at the end of the model numbers listed above to indicate “Tray Packaging”.
