DET_VIN
In closed ALC-loop mode, avoid directly loading pins
AMP_OUT and DET_VIN with capacitance in excess of
10pF on each pin. In closed ALC-loop mode, this can
cause ringing or instability in the power-control loop.
As in any closed-loop system, one must be careful not
to load DET_VIN or AMP_OUT with additional external
circuitry. Therefore, it is suggested that in the closed-
loop ALC mode, no additional connections be made to
DET_VIN or AMP_OUT. AMP_OUT and DET_VIN support
a total trace routing capacitance of 10pF or less. Connect
pin 9 to the RF ground plane with a via separated from
the exposed pad (EP) ground connection. Pin 9 must
not connect to the exposed pad or share a ground with
DETECTOR
Layout Considerations
The pin configuration of the MAX2092 is optimized to
facilitate a very compact physical layout of the device
and its associated discrete components. The exposed
pad of the device’s 20-pin TQFN-EP package provides a
low thermal-resistance path to the die. It is important that
the PCB on which the device 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. Pin 9 must not
connect to the exposed pad or share a ground with any
other component and must connect directly to the solid
ground plane below.
any other component, and must connect directly to the
solid ground plane below. As a reference, refer to the
