Murata PE25203 User Manual page 16
Divide-by-2 and -3, 4a charge pump, capacitor divider
Table of Contents
VDD must be measured from the EVK. Use VDD test point for this measurement. After measuring VDD, insert value
in the Excel file.
Set the voltage levels where the charge pump is required to automatically change the division ratio.
■
Vtrigger_low: Charge pump changes from divide-by-3 to divide-by-2.
■
Vtrigger_high: Charge pump changes from divide-by-2 to divide-by-3.
It is recommended not to set Vtrigger_low below 8.6V to avoid taking the charge pump system into UVLO conditions
under heavy load operation.
After Vtrigger low/high voltages have been set, insert them into the Excel file.
