Datasheet
• Non-isolated Features • Synchronous rectification design • Adjustable output voltage **DC/DC Converter** • 2, 3, 4 & 5AMP adjustable positive step down Switching integrated switching regulator • Over load protection Regulator • Continuous short circuit protection **R-5xxxPA_DA** • Efficiency up to 96% ee REC Description **2,3,4,5 Amp** The R-5xxxA series is a high performance 1.2V to 5.5V, 2Amp to 5Amp, 12-Pin SIP (single in-line **SIP12** package) integrated switching regulator (ISR). The synchronous - rectified design yields excellent efficiencies up to 96%. Short circuit protection reduces the short circuit input current to under 50mA. ©NN **Vertical &** Autosense function compensates for any losses in long circuit loops. **Horizontal** Selection Guide **Single Output** |Selection Guide<br>Part<br>Input|Selection Guide<br>Part<br>Input|Output|Vout|Output|Efficiency|Efficiency|Efficiency|Max.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
