THERMAL CONSIDERATIONS

As the ACE712E has a power MOSFET with internal current limit up to 5A, heat dissipation is always

needed to be considered when designing the PCB for such high-power step-up converter. ACE712E

employs a package of DFN3x3-12 with only 3

is crucial for one to lay a large area of copper (in most case, it is the large ground plane), directly

contacting the thermal pad of the chip through more than 2 large vias from bottom, to spread the heat

away to the ambient environment as fast as possible.

A thicker copper foil is always recommended to help the heat dissipation, so a PCB with 2oz copper

thickness is a much better choice than that of 1oz copper.
