From the project
1. Input & Filtering: 5V enters via J1. It is immediately protected by a Polyfuse and filtered by a Ferrite Bead to reduce high-frequency noise. 2. Polarity Protection: An LM66100 ideal diode provides extremely low-loss protection against reverse voltage on the input. 3. Gated Co
1. Input & Filtering: 5V enters via J1. It is immediately protected by a Polyfuse and filtered by a Ferrite Bead to reduce high-frequency noise. 2. Polarity Protection: An LM66100 ideal diode provides extremely low-loss protection against reverse voltage on the input. 3. Gated Control: The TPS22918 load switch acts as the master gate. A physical SPDT slide switch (SW1) controls the enable pin, allowing the user to safely toggle the ±12V rails. 4. Isolated Conversion: The A0512S-2WR2 performs the heavy lifting, converting the 5V input to isolated ±12V outputs. This isolation helps prevent…
