Description

The Bel VRPB-15Cxxx is part of the low cost non-isolated dc/dc converter series. The modules use a SIP package

for ease of layout and space savings. The output is closely regulated and the efficiency is typically 93% at 2.5 Vdc

output at full load. Typical features include remote on/off, under-voltage lockout, over-current protection and short

circuit protection.
