Description
The Bel SRBC-16E2Ax 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-16E2Ax has a sequencing feature that enables designers to
implement various types of output voltage sequencing when powering. The efficiency is typically 92% at 3.3 Vdc
output at full load.

1. SRBC-16E2Ax 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.
