Solar Power System Design
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?
