![Automotive 12V to 5V USB charger assembled PCB]
This project presents a nominally 12V to 5V step down power adapter for use in a motor vehicle to supply 5V at up to 2A from a USB socket.
It is intended to be plugged into a cigar lighter socket in a car or other vehicle and can be used with any device that is normally charged from a 5V USB power outlet at up to 1.8A.
Although most rec...
Simulations created in development support of:
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.
