4. Devices mounted on 2oz copper, minimum recommended pad layout, FR-4 PCB.
OUT
3. The PCB layout copper area should be much greater than 10*10mm at the Vcc pins (5&6) of the AP1580, if you need large PD or low Tc&T
IN
The absolute maximum ratings are rated values exceeding which the product could suffer physical damage. These values must therefore not
A
be exceeded under any conditions.
