Description
The Bel S7BC-10E2Ax is part of the non-isolated DC/DC power converter series. The modules use a SMT
package. These converters are available in a range of output voltages from 0.75V to 3.63V over a wide range of
input voltage (Vin = 4.5V-14V). The Bel S7BC-10E2Ax has a sequencing feature that enables designers to
implement various types of output voltage sequencing when powering. The efficiency is typically 93% at 3.3V
output at 12V input at full load.

1. S7BC-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.
