Description

The Bel SRBC-10E2Ax is part of the non-isolated dc/dc converter series. The modules use a SMT 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 SRBC-10E2Ax has a sequencing feature that enables designers to

implement various types of output voltage sequencing when powering. The efficiency is typically 93% at 3.3 Vdc

output at 12 Vdc input at full load.

1. SRBC-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.
