Description
The Bel VRAE-10E1AR 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.
