characteristic fluctuation with temperature and the frequency.The resistor R connected in series with C is effective
for phase correction at high frequency, as a result, it improves the oscillation allowance.
hence increases the output power of the IC.
To prevent oscillation, it is advisable to use C (Zobel network capacitor). Using polyester film capacitor has small
The capacitor C connected between the output and bootstrap pin helps to increase the output dynamic range and
