Description

The Bel x7AH-10Jxx0 is part of the low cost non-isolated DC/DC power converter series. The modules use a

SMD or SIP package for ease of layout and space savings. The output is closely regulated and the efficiency of

1.5V output is typically 88% at full load. Typical features include remote on/off, input under voltage lockout, over

current protection and short circuit protection.
