This document introduces the non-isolated DC/DC converter series from Bel Fuse Inc., featuring over temperature protection, high efficiency, and low cost.
The VRPB-15Cxxx family is a low‑cost, non‑isolated DC/DC converter series offered in a SIP package for compact layout. The modules deliver up to 15 A output current with high efficiency (up to 93 % at 2.5 V) and include features such as remote on/off, under‑voltage lockout, over‑current and short‑circuit protection.
The document lists detailed electrical parameters, mechanical dimensions, and thermal derating curves, as well as pin‑out and recommended PCB layout. It also covers compliance information, including RoHS certification and environmental directives.
| Input Voltage (continuous) | -0.3 V to 4 V |
|---|---|
| Maximum Output Current | 15 A |
| Typical Efficiency (2.5 V output) | 93 % |
| MTBF | 4,163,010 hours |
The converters can deliver up to 15 A of output current.
Typical efficiency is about 93 % at a 2.5 V output under full load.
Remote On/Off signal low (unit off) is –0.3 V to 0.8 V, and signal high (unit on) is 2.5 V to 5.5 V for the S version.
