Technical Information (continued)
To prevent oscillation, it is advisable to use RC (Zobel network) at output. C of polyester film capacitor has smaller
characteristic fluctuation with temperature and frequency. The resistor R connected in series with C is effective for
phase correction at high frequency, and as a result, it improves the oscillation allowance.
The output pins 7, 12 and V
The turn ON time in the AN5273 is determined by the capacitance value of C
will 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
