ACE724C

18V 2A Synchronous PFM/PWM Buck Converter

VER 1.5

Normally, people use 3.3nF and 5.6Kohm RC for compensation to keep the loop stable. However, if one

needs to have faster load transient response, 3.3nF and 8.5Kohm is recommended.

Thermal consideration

ACE724C 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. ACE724C 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.
