linear DESIGN FEATURES LTMag-V18N02-14-LTC4355_57-MeilissaLum service manual
The article discusses how traditional Schottky ORing diodes reduce available voltage and dissipate significant power in high-current systems. It introduces MOSFET-based ideal diode solutions as a more efficient alternative that reduces heat dissipation and simplifies PCB layout.
Specifically, the document highlights the LTC4358 controller, which includes an internal MOSFET pass element. This device offers lower voltage drop and power loss compared to standard Schottky diodes like the B530C, allowing for smaller packages and eliminating the need for bulky heat sinks in many applications.

How do ideal diodes protect against wiring errors?
They provide protection similar to discrete diode solutions, making wiring errors transparent to the load or preventing damage through reverse input protection networks.
