• Manufacturer: Maxim Integrated Products

The following points are in order of decreasing importance:
1) Minimize switched-current and high-current ground
2) Connect the input filter capacitor less than 5mm

loops. Connect the input capacitor’s ground, the out-
put capacitor’s ground, and PGND at a single point.
Connect the resulting island to AGND at only
one point.
away from IN. The connecting copper trace carries
large currents and must be at least 1mm wide,
preferably 2.5mm.

3) Place the LX node components as close together
4) A ground plane is essential for optimal performance.
TRANSISTOR COUNT: 4305
PROCESS: BiCMOS
and as near to the device as possible. This reduces
noise, resistive losses, and switching losses.
In most applications, the circuit is located on a multi-
layer board, and full use of the four or more layers is
recommended. Use the top and bottom layers for
interconnections and the inner layers for an uninter-
rupted ground plane. Avoid large AC currents
through the ground plane.
