ML4890

High Efficiency, Low Ripple Boost Regulator

Micro Linear Corporation 

LAYOUT

Good PC board layout practices will ensure the proper

operation of the ML4890. Important layout considerations

include:

• Use adequate ground and power traces or planes

• Keep components as close as possible to the ML4890

• 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 ML4890 ground pins,

and the input and output capacitors

A sample PC board layout is shown in Figure 7.
