Description
The Bel V7PB-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 3.3V 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.
