APPLICATION INFORMATION
DIODE SELECTION
PCB LAYOUT GUIDE
4
Schottky diodes with higher current ratings usually have lower forward voltage drop,
larger diode capacitance and fast reverse recovery, it is the ideal choices for APE2901
applications. The forward voltage drop of a Schottky diode represents the conduction
losses in the system, while the diode capacitance (CT or CD) represents the switching
losses. For diode selection, both forward voltage drop and diode capacitance need to be
considered.
When laying out the PC board, the following suggestions should be taken to ensure
proper operation of the APE2901. These items are also illustrated graphically in below.
1. The power traces, including the GND trace, the SW trace and the VCC trace should be
kept short, direct and wide to allow large current flow. Put enough multiply-layer pads
when they need to change the trace layer.
2. Do not trace signal line under inductor.
