I have previously designed and biult a 8 channel RGB strip controller. This controller has served well. But sadly the output transistors have gone End of Life.
Artwork Design
I did two things to rectify this situation, I found a replacement device and ordered 500 to try out. I also decided to look for some smaller devices and have been taken with the DMN6040SSD-13 yu Diodes Incorporaate.
In short, the specs are:
Dual N-Channel, Vds=60 V, Id=4.4 A & Rds On =55 mOhms (Vgs =4.5V)
Package/Case: SOIC-8
1st Prototype
I also added a couple of fuses , Rj45s and dropped the switch mode power supply for a simple linear. For 12Volt operation this is fine. for higher voltages, I will change the LM7805 to Murata Switcher.
– Now to test the unit.
