Power System Design Overview

fluxfer

I want to design a power system that takes input from a solar panel, a rechargeable battery, or USB, with automatic power selection. The system should provide regulated 5V, 3.3V, and 1.8V outputs.
Project Requirements:
  • Inputs:
    • Solar Panel (6V, 2W)
    • USB Power Input (5V)
    • Li-Ion Battery (3.7V, 2000mAh)
  • Power Management:
    • Battery Charger IC (MCP73831 – Charges battery from solar or USB)
    • Power Selection Circuit (Automatically switches between power sources)
  • Voltage Regulation:
    • Boost Converter (MT3608 – Steps battery voltage up to 5V)
    • Buck Converters:
      • 3.3V Regulator (AP7333-33)
      • 1.8V Regulator (AP7333-18)
  • Protection Components:
    • Schottky Diodes (Prevent reverse current)
    • Capacitors (For power stability)
  • Indicators & Outputs:
    • LED Indicators (Charging & Power status)
    • Regulated Outputs: 5V, 3.3V, 1.8V
Can you generate a block diagram showing how these components connect?

This diagram shows the power flow starting from your Solar Panel, USB Power, and Li-Ion Battery (charged via the MCP73831 Charger), then merging into the Power Selection Circuit. The selected input is boosted using the MT3608, and the resulting 5V is used directly for indicators and further downregulated to 3.3V and 1.8V using the respective buck converters.
