Hi,
I am using a Teensy 3.6 and wondering, what will happen if the VIN voltage of 6V is accidentally exceeded.
In the circuit diagram I can see the LP38691 LDO and a fuse F1 with 500mA (a "polyfuse" i guess).
Vin voltage is specified to <6V, the LDO is specified for <10V or absolute maximum 12V.
I want to use a MH-mini360 adjustable step-down converter to use a 15V supply.
Of course i would adjust it's output to about 5V before connecting.
But it could happen, that the adjustment pot has got a loose contact,
so that the voltage accidentally goes up to 15V.
Will the poly fuse in this case clamp the voltage and protect Teensy (and a device connected to the USB-host port)?
By the way:
Is it correct to leave the pads "H" and 5V connected and just cut the pads VUSB and VIN, when the Teensy is powered by the step-down-converter and
a device is connected to the USB-host port while occasionally the PC has to be connected to the micro-USB programminig interface?
