Re: H5CC driver
Minimum input is 8V (as per previous info in this thread). Max input voltage will be 24V.
Headroom depends on output current, some info in this thread already. More testing to do before I release production boards late April.
Ok, at 5A output (max my power supply can provide on the input) and 9.82V Vf the driver needed 10.82V at the input to be in regulation, below 10.82V the output current would drop - basically direct drive. So, at 5A the driver requires 1V of headroom (this is with the low Rdson reverse polarity protection FET in place).
There is no thermal protection on the 'dumb' driver. h6flex will have all the 'good' stuff like thermal monitoring and input voltage monitoring etc etc.
The h6cc with a d2flex would have thermal protection by utilizing the d2flex monitoring and PWM rollback.

What is the minimum and maximum input voltage range and how much volts does it have to be above led vin to stay in regulation ? Also what temp will thermal shutdown occur? Will it be fine to drive from 7.2v source to power 24 xpg's in 12 strings of series ( alll strings paralleled) ?
