PCB layout guidelines
Careful printed circuit layout is extremely important to avoid causing parasitical
capacitance and line inductance. The following layout guidelines are recommended to
achieve optimum performance.
• Please the boost converter diode and inductor close to the LX pin and no via.
Keep traces short, direct, and wide.
• Please ceramic bypass capacitors near the input/output pin.
• Locate all feedback sense resistors as close to the feedback pins as possible.
• The ground connections of VIN and VOUT should be as close together as possible.
