Two articles about 5v to 3.3Buck module

Overview

The RY3415 and PL5900 boards
are so small that JP sent me 7
PL5900s using a 3.3V fixed package

Note: The front and rear filter capacitors of RY3415 are 22uF, and those of PL5900 are 10uF.
The rated current of RY3415 is 1.5A, and the rated current of PL5900 is 700mA.

Help! PCM2707 is not working properly
A year ago, a manufacturer asked me to draw a board that uses PCM2707 to output I2S. At that time, everything was normal when I tested it myself. Two days ago, I used the board I made before to assemb
100 Rules of Thumb for Signal Integrity----
It was originally 100, but only 90, but it's not badAbstract : As modern digital electronic systems break through the 1GHz barrier, PCB board-level design and IC package design must take into account
