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.
• Please ceramic bypass capacitors near the charge-pump input pin.
• Locate all feedback resistive dividers as close to their respective feedback pins as
• Separate GND and PGND areas connected at only one point under the IC.
• Use wide traces and trace length is short as possible.
