NON-ISOLATED DC/DC CONVERTERS 8 Vdc - 14 Vdc Input 0.8 Vdc - 3.63 Vdc / 30 A Outputs VRBG-30A1A0 RoHS Compliant PRELIMINARY Rev.A • Non-Isolated • Input Under Voltage Lockout • Fixed Frequency • Over Temperature Shutdown • High Efficiency • Short Circuit Protection • Wide Trim • Remote On/Off • Low Cost • Industrial Temperature Range • Remote Sense Description The Bel VRBG-30A1A0 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 0.8 Vdc to 3.63 Vdc over a wide range of input voltage (Vin = 8 Vdc - 14 Vdc).The efficiency is typically 92% at 12 Vdc input and 3.3 Vdc output at full load. Part Selection Output Voltage Input Voltage 0.8 Vdc - 3.3 Vdc 8 Vdc - 14 Vdc Max. Output Current 30 A Max. Output Power 99 W Typical Efficiency 92% Model Number VRBG-30A1A0 Notes: 1. Add “G” or “R” suffix at the end of the model number to indicate Tray or Tape and Reel packaging. 2. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.
