7 / 10 page ACE724C 18V 2A Synchronous PFM/PWM Buck Converter VER 1.5 7 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. Component selection When setting up the ACE724C for different output voltage, please use following recommended component value for the best performance. VOUT(V) COUT(µF) L(µH) 8 22*2 22 5 22*2 15 3.3 22*2 10 2.5 22*2 6.8 1.8 22*2 4.7 1.2 22*2 3.3 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. Packing Information |
