HW-636 Step Down Buck Power Module

The HW-636 is a DC-DC buck step down power converter. It has a relatively high input voltage range (6.5 -60V) with an output of upto 30V at 5 amps. Here is my 3D design of the module for modelling purposes, hence only the sizable PCB components are visible.

If you're like me, it doesn't matter how much care you take, it's still possible to miss details in the 3D design. Typical missed details that will lead you into problems include:

• Parts encroaching on others.
• Hole spacings misaligned.

A 3D model of each component incorporated into your design helps avoid some of the design pitfalls.

I've included the STEP CAD file to assist people to incorporate the model into their designs.

My print is made in PETG 1.75mm Aurarum neutral filament, with 0.2mm layer height and 15% infill on a PRUSA I3 MK3S printer.

I hope you can find this design useful, too.

Remember to leave me some feedback or even a tip to keep me enthused to make more of these drawings.
