Feature Descriptions
Output Voltage Programming
The output voltage of the Austin MicroLynx
SIP can be programmed to any voltage from 0.75Vdc
to 5.5Vdc by connecting a resistor (shown as Rtrim in
Figure 30) between Trim and GND pins of the
module. Without an external resistor between Trim
and GND pins, the output of the module will be
0.7525Vdc. To calculate the value of the trim resistor,
Rtrim for a desired output voltage, use the following
equation:
Rtrim is the external resistor in Ω
Vo is the desired output voltage
For example, to program the output voltage of the
Austin MicroLynx
calculated as follows:

output voltage using an external resistor
Table 1 provides Rtrim values for most com
output voltages.

LOAD
Using 1% tolerance trim resistor, set point tolerance
of ±2% is achieved as specified in the electrical
specification. The POL Programming Tool, available
at
section, helps determine the required external trim
resistor needed for a specific output voltage.
The amount of power delivered by the module is
defined as the voltage at the output terminals
multiplied by the output current. When using the
trim feature, the output voltage of the module can
be increased, which at the same output current
would increase the power output of the module.
Care should be taken to ensure that the maximum
output power of the module remains at or below the
maximum rated power (P
Voltage Margining
Output voltage margining can be implemented in
the Austin MicroLynx
resistor, R
margining-up the output voltage and by connecting
a resistor, R
Figure 31 shows the circuit configuration for output
voltage margining. The POL Programming Tool,
available at
Design Tools section, also calculates the values of
R
voltage and % margin. Please consult your Lineage
