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 V 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.
The VRPB-15E series from Bel Fuse offers low‑cost, non‑isolated DC/DC converters in a compact SIP package. Features include high efficiency, over‑temperature protection, remote on/off, under‑voltage lockout, and wide input/output voltage ranges.
The datasheet lists detailed electrical specifications, thermal derating curves, mechanical dimensions, and compliance information such as RoHS. It also provides recommended PCB layout and pin‑function details for designers.
