Thermal consideration

ACE724 is high efficiency Buck converter, which means it consumes very few power when converting

the high voltage to low voltage. However, when output power is very large, like 5V/2A, the output power is

as high as 10W, a heat dissipation path is strongly recommended to be routed on PCB. ACE724 has two

different SOP8 package. For the normal SOP8, the heat is conducted out via Pin 4 (GND), so the heat

dissipation route on PCB should be connected to the Pin 4 of the chip. If ESOP8 is selected, the heat

dissipation copper area should be exposed and connected to the exposed pad underneath the chip body.

When output power is larger than 10W, the ESOP8 package is recommended
