Description
The Bel xRPF-15B1AC 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 can be trimmed from 1.2 Vdc
to 3.3 Vdc. The efficiency is typically 93% at 3.3 Vdc output at full load. Typical features include remote on/off,
under-voltage lockout, over-current protection and short circuit protection.
