Layout and Grounding
Good layout is important, primarily for good noise perfor-
mance.
1) Mount all components as close together as possible.

2) Keep traces short to minimize parasitic inductance

and capacitance. This includes connections to FB.
3) Use a ground plane.
Noise and Ripple Measurement
Accurately measuring the output noise and ripple is a chal-
lenge. Brief differences in ground potential between the
MAX850–MAX853 circuit and the oscilloscope (which result
from the charge pump’s switching action) cause ground
currents in the probe’s wires, inducing sharp voltage spikes.
For best results, measure directly across the output capaci-
tor (C4). Do not use the ground lead of the oscilloscope
probe; instead, remove the probe’s tip cover and touch the
ground ring on the probe directly to C4’s ground terminal.
You can also use a Tektronix chassis mount test jack (part
no. 131-0258) to connect your scope probe directly. This
direct connection gives the most accurate noise and rip-
