RFMW Expert Product Pick: pSemi PE25304 72W Charge Pump Capacitor Divider

I chose the pSemi PE25304 Ultra-thin, high-efficiency 72W charge pump capacitor divider because power architects are under constant pressure to increase power density while simplifying implementation. The transition to 48V power distribution has helped address efficiency losses across modern systems, but it has also introduced new design challenges related to thermal management, board space constraints, and power conversion complexity. As data centers, networking platforms, base stations, optical systems, and high-performance test equipment continue to demand more power in smaller footprints, engineers need solutions that streamline design without compromising efficiency or reliability. The PE25304 meets those requirements by integrating a high-performance DC-DC converter into an ultra-thin module that minimizes external component count and eliminates the need for compensation loop design, helping accelerate development while delivering robust power conversion.

The PE25304 combines a fixed divide-by-4 conversion output architecture with a wide 20V to 60V input range, making it ideally suited for 48V bus applications. Delivering up to 72W of output power and supporting load currents up to 6A, the module achieves efficiency levels as high as 96.5%, helping reduce power loss and thermal management requirements in space-constrained systems. Its compensation loop-less charge pump architecture simplifies implementation, while features such as external clock synchronization, open-drain power-good indication, over-current protection, and over-temperature protection enhance system-level performance and reliability. The compact 11.5 × 9.5 × 2.0 mm LGA package further enables designers to maximize power density without compromising efficiency. For higher power demands, up to four devices can be used in parallel for increased current.
