MAX2091
27
Typical Application Circuit
(EP) of the MAX2091’s 20-pin TQFN package provides a
low thermal-resistance path to the die. It is important that
the PCB on which the MAX2091 is mounted be designed
to conduct heat from the EP. In addition, provide the EP
with a low-inductance path to electrical ground. The EP
must be soldered to a ground plane on the PCB, either
directly or through an array of plated via holes.
