GENERATING THE HIGH VOLTAGE SUPPLY
It is possible to use a boost converter such as the Analog Devices
ADP1613 to generate the high voltage charge pump supply
from a lower voltage rail without degrading PLL performance.
To minimize any switching noise feedthrough, ensure that
sufficient decoupling is placed close to the charge pump supply
pin (Pin 6). Care should be taken to use capacitors with the
appropriate voltage rating; for example, if using a boost converter
to generate a 20 V VP supply, use capacitors with a rating of
20 V or higher.
The design of the boost converter is simplified using the
ADP161x Excel-based design tool. This tool is available from the
ADP1613 product page. Figure 30 shows the user inputs for an
example 5 V input to 20 V output design. To minimize voltage
ripple at the output of the converter stage, the Noise Filter
option is selected, and the Vout Ripple field is set to its
minimum value. The high voltage charge pump current draw is
2 mA maximum; therefore, a value of 10 mA is entered in the
Iout
field to provide margin. When tested with the ADF4150HV
evaluation board, this design showed no evident switching
spurs at the VCO output.
