7 / 9 page ACE714 High Efficiency Low Noise PFM Step-up DC/DC Converter VER 1.3 7 4.PCB Layout Layout is critical to achieve clean and stable operation. The switching power stage requires particular attention. Follow these guidelines for good PC board layout: 1) Place decoupling capacitors as close to the IC as possible. 2) Connect input and output capacitors to the same power ground node with a star ground configuration then to IC ground. 3) Keep the high-current paths as short and wide as possible. 4) If possible, connect IN, SW, and GND separately to a large copper area to help cool the IC to further improve efficiency and long-term reliability. 5) Ensure all feedback connections are short and direct. Place the feedback resistors as close to the IC as possible. 6) Route high-speed switching nodes away from sensitive analog areas Figure 4. Recommended Component Placement |
