Description

Simulations created in development support of:

https://easyeda.com/example/Automotive_12V_to_USB_5V_2A_output_power_adapter_-L1xrlfxrJ

Contains:

  1. Design and simulation of a stable input filter for the 12V to 5V SMPS.

2, Several outline schemes for the output overvoltage protection shunt clamp.

The actual project as shown in the above link has been successfully built and tested.
