After replaced the PCB of DDC 18W, the ampere increased from 1.5A to 1.8A,
the flow rate increased about 20% (using stock top)
The audible noise is also increased, it should be caused by the increased rotation speed
The IC leg spacing is only 0.33mm, drag soldering is the only way
I have accidentally reverse the diode and the most expensive IC burn immediately at connecting the power
This controller TB6588FG is an all-in-one design, it has built-in overheat and restart protection, only a few external component can get it work, the original laing design is unnecessary complex.
This IC also have built-in speed control, connecting a variable resistor can adjust the rotation speed.
More information can be found in the Toshiba semiconductor website, it has datasheet and official circuit to follow.
Want to show off that smoking system or your latest creation?
