The output pins 7, 12 and V
The turn ON time in the AN5272 is determined by the capacitance value of C
would turn ON faster.
The turn OFF time is dependent on the capacitance value of C
declines faster than RF voltage. To solve this, increase the discharge time of V
values of C
The recommended values of capacitance for C
Stand-by function can be implemented in the AN5272 by external solution. It is realised by pulling the RF voltage
to low and output voltage would follow RF as shown in the diagram.
