Lae801p Rev 20 Schematic Better Jun 2026

He was about to desolder the MOSFET array for the third time when his email pinged. It was a message from the older, reclusive engineer who had designed the original platform, a man named Arthur Vance. The subject line was simple:

With recommended Css = 0.47µF, startup time extends to 4.7ms, preventing inrush current spikes. lae801p rev 20 schematic better

Perhaps the most elegant fix in Rev 20 involves the feedback network. Earlier revisions tied the feedback pin directly to the output rail with a simple resistor divider. This worked, but it made the loop sensitive to output capacitor ESR. He was about to desolder the MOSFET array

The charging IC senses a short-circuit downstream and turns off the gates of the protection MOSFETs to protect the board. startup time extends to 4.7ms
