Description
The Bel VRBC-10E2Ax 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 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.

1. VRBC-10E2Ax series of modules include a sequencing feature that enables users to implement
various types of output voltage sequencing in their applications. This is accomplished via an additional
sequencing pin. When not using the sequencing feature, either tie the SEQ pin to Vin or leave it
unconnected.
