> That means that the lower limit of the supply voltage is about 5V but the upper limit is much less than 40V. That's because the input capacitor is rated at 25V, so I would not suggest running it on more than 20V.
Even that will stretch it without rework. The higher the voltage difference, the higher the heat losses - at the minimum you'll need a heatsink, at higher voltages I'd even go for active ventilation.
