LAYOUT
Good PC board layout practices will ensure the proper
operation of the ML4790. Important layout considerations
include:
• Use adequate ground and power traces or planes
• Keep components as close as possible to the ML4790
• Use short trace lengths from the inductor to the VL pin
and from the output capacitor to the VBOOST pin.
• Use a single point ground for the ML4790 ground pins,
and the input and output capacitors
A sample PC board layout is shown in Figure 8.
