14 Powering Up Your Design Using the evaluation kit arrangement, designers can set up, evaluate, and modify the many operating parameters and modes of these PMICs, such as sequencing among rails (Figure 10). The kit also eases measurement of figures of merit such as efficiency under various conditions, critical for meeting run-time and thermal objectives (Figure 11). The EVK User's Guide also provide a complete schematic, BOM, and layout of the four layers of its PC board if designers want to use that as a starting point for their own implementation. Figure 11: The evaluation kit also simplifies the measurement of important performance metrics such as the efficiency of the various PMIC rails under different operating conditions, shown for Buck1 and Buck2 of the ACT88329 PMIC. (Source: Qorvo) Figure 10: Using the evaluation kit and associated instrumentation, designers can configure, evaluate, and reconfigure key parameters such as relative sequencing of the various power rails. (Source: Qorvo) Conclusion Designers benefit from PMICs, which do more than just provide multiple DC rails via buck, boost, and LDO regulators and manage their sequencing and interaction. Sophisticated PMICS in the Qorvo ActiveCiPS™ family also support the initial configuration of various critical performance attributes of the multiple power rails along with reconfigurability. The result is that designers can develop tailored, optimized multi-rail performance for their power-distribution topology.
