Description
The Bel VRPB-15Exxx series are part of the low cost non-isolated dc/dc power converter series. These modules
use a SIP package for ease of layout and space savings. The output is closely regulated and the efficiency at
3.3 Vdc output is typically 92% at full load. Typical features include remote on/off, under-voltage lockout, wide
input voltage range, wide output trim range, over-current protection and short circuit protection.
