Modifications
These evaluation modules are designed to provide access to the features of the TPS561201. Some
modifications can be made to this module.
3.1
Output Voltage Setpoint
To change the output voltage of the EVMs, it is necessary to change the value of resistor R1. Changing
the value of R1 can change the output voltage above 0.768 V. The value of R1 for a specific output
voltage can be calculated using
.
(1)
lists the R5 values for some common output voltages. Note that the values given in
are
standard values and not the exact value calculated using
.
