AP1534 18V adjustable DC-DC power supply, low ripple

Overview

The design is based on AP1534 . The 1.5A output can be used normally without heat dissipation. It has an EN pin to control the shutdown.

Tested under load, input 9.25V, 1.05A, output 4.54V 1.46A, the final measured efficiency is about 73% when it is around 5V

Under load, the ripple is very low. Of course, I did not use a better oscilloscope. This is because I am lazy.
