8 / 9 page UC3750 Preliminary CMOS IC UNISONICTECHNOLOGIESCO.,LTD 8 of 9 www.unisonic.com.tw QW-R502-360.a DESCRIPTION INFORMATION(Cont.) 12. PCB Layout Recommendations Good PCB layout is important in switching mode power conversion. Careful PCB layout can minimize ground bounce, EMI noise and unwanted feedbacks that can affect the converter performance. 13. Grounding The output power return ground, the input power return ground and the device power ground should be connected at the Star-ground. Feedback signal path must be separated from the main current path and sensing directly at the anode of the output capacitor. All high current running paths must be thick enough for current flowing through and producing insignificant voltage drop along the path. 14. Components Placement Power components including input capacitor, inductor and output capacitor must be placed as close as possible. All connecting traces must be short, direct and thick. In order to avoid unwanted injection of noise into the feedback path high current flowing and switching paths must be kept away from the feedback pin terminal. 15. Feedback Path Feedback of the output voltage must be separated from the power path. The output voltage sensing trace to the feedback pin should be connected to the output voltage directly at the anode of the output capacitor. |
