A high power density resonant switched capacitor DC-DC converter (rPOL2V5) has been developed as a possible alternative to the bPOL2V5, of particular interest to the CMS High-Granularity Calorimeter (HGCAL) due to the relatively compact 12nH air-core inductor that it requires. The converter is based on an ASIC developed in a 130nm CMOS technology. It is powered by a 2.5V input, it can supply a maximum current of 3A to the output voltage range 1-1.5V. This work presents the strategies adopted at ASIC and PCB level to bring the converter to maturity, and the electrical and radiation characterization results..
