    Default Supernew high-side diode and TEC smart driver :)

    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

    suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.

    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

    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
