Description
The xRPC-04C50x series are part of low-cost non-isolated boost dc/dc converters that operate from a nominal
3.3 V source. The modules use a SIP package for ease of layout and space savings. The output is closely
regulated and the efficiency for 5.0 V output is typically 92.5% at full load. Standard features include high
efficiency, fixed frequency, industry standard footprint and high power density.
