Reviewed the Design Specification and extracted the locked behaviors, operating assumptions, and unresolved gaps that affect simulation setup.
Used those requirements to populate the existing Simulation & Test Results document as a living record linked back to the design spec.
Ran and documented initial architecture-level simulations for solar qualification, USB input budget, source switching priority, battery-charging behavior, boosted-output modes, and the always-on 3.3 V rail.
Added plots, result tables, observations, issues, and reusable insights to the results document, including first-pass implications for USB current budget, solar qualification thresholds, and required source-priority behavior.
✅ Initial simulation data for solar, USB, source switching, battery charging, boost behavior, and 3.3 V regulation were captured and stored in the results document.
✅ The document now includes clear sectioning for plots, tables, observations, issues, design implications, and reusable insights for future iterations.
Next steps
The main follow-up is a second simulation pass using a more detailed solar I-V model and dedicated converter-level simulations for the CN3063/RT8059/MT3608 stages. I can do that next if you want to tighten the architecture before schematic capture.
Low-Power Embedded Power Management Board: Files & Simulations demo
Power management board for a low-power embedded system with solar panel, 1S LiPo battery, and USB 2.0 inputs; charges the battery from available external power, powers the system from battery when external sources are absent, prioritizes USB over solar, and generates selectable boosted 12V or 5V output plus a regulated 3.3V rail.
