A 5V 40A DC-DC module based on PW22ASAB

Function Introduction:
Two PW22ASAB connectors can provide a total of up to 40A of 5V power supply, fully meeting the needs of multi-bay hard drives. Recommended for use in environments with 8-16 drives (8-bay tested).
The layout
uses a 4-layer board. The top CN1 and CN3 are 12V input terminals, with the same wiring sequence as the 8-pin power cable for graphics cards.
Considering different usage environments, the output port wiring sequence needs to be carefully checked.
The bottom CN4, CN6, and CN5 are output ports, consisting of a two-pin 12V direct output, a two-pin 5V output, and a 4-pin GND
input. The CPU 8-pin 5569 connector (straight-through, solid pin)
and output ports are CPU 8-pin 5569 connectors (angled, solid pin).
Again, the output port wiring sequence needs to be carefully checked.
Filter Capacitors
: This module's input and output capacitors consist of 8 solid-state through-hole capacitors and 16 tantalum capacitors.
These capacitors also determine the module's ripple performance (and price); pay attention to the packaging and voltage rating when selecting them.
