Power System Design Guide

Below is a Mermaid block diagram that outlines the interconnection of the key power system components as described:
Diagram
This diagram shows:
- The 240V AC Input is stepped down and rectified by the Transformer & Rectifier to provide a DC bus.
- The DC output flows through Protection elements (Schottky diodes and capacitors).
- The Boost Converter (MT3608) then raises the voltage (from battery or DC bus) to the level needed for further regulation.
- The boosted voltage is branched off to:
- A buck converter for final 9V output
- A buck converter for 3.3V output (using the AP7333-33)
- (And a buck converter for 1.8V output using the AP7333-18, if needed for internal auxiliary functions.)
- LED Indicators monitor the status of the outputs.
Feel free to adjust the block labels as needed for your design documentation.
