Supernew high-side diode and TEC smart driver :)

[Bbe]

Hi guys!

A lot of new drivers came in the past week, that's great! I'm not going to stay on the sidelines

My boards:




Dimensions 50x50cm
Input Voltage - 12...14V
Overall efficiency: TEC driver side - >85%, diode driver side - >70%
...
Output TEC current - up to 5A
Output TEC voltage - 10V, may be limited to 3, 5, 8V (for different models of Peltier)
TEC operation - PWM
Temperature accuracy - better than 1 °C
TEC sensor - NTC
...
Diode channels - 2
Highside - yes
Output LD current - up to 2.5A/ch
Setting the threshold current - up to 400 ma/ch
Standby threshold current mode - yes (many people call it "SBS technology")
Standby sensitivity - around 0.15V
Modulation frequency - 100khz/1.5db nonlinearity
...
Protection from unstable supply voltage
Onboard supply voltage converter
REAL soft start (why some people "start delay" call the soft start?)
Overcurrent protection
Laser module overheating protection (second NTC sensor)

...to be continued

those look great. please let me know when they've been tested and are available!

These boards have been made ​​to replace my old drivers in my projectors. They been tested there
Now I am preparing a new revision of this driver

[edison]

Nice design, great work!!!!

[edison]

Currious about the big resitors though....

[Bbe]

I had a large supply of these resistors and so they moved to this project

[slicklasers]

How much are they?

[Bbe]

ha-ha, how much give?

[slicklasers]

$4.95 lol

[ZeroPoint]

I would like to see a reliable source of good drivers like these. I love the Flexmods but they are never available when I need them :/ I've been thinking about designing my own as well, maybe I should.. but for now, I would be interested in yours
