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 Bel VRBC-10E2Ax has a sequencing feature that enables designers to implement various types of output voltage sequencing when powering. The efficiency is typically 94.3% at 3.3 V 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-10E2AL Model Number Active High VRBC-10E2A0 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.
