PRODUCTION DATA
TI recommends a 0.1-μF ceramic capacitor or larger for the bootstrap capacitor (Cboot). For applications where the input voltage is close to output voltage, TI recommends a larger capacitor, generally 0.1 μF to 1 μF to make sure of plenty of gate drive for the internal switches and a consistently low RDSON. TI recommends a ceramic capacitor with an X7R or X5R grade dielectric with a voltage rating of 10 V or higher because of the stable characteristics over temperature and voltage.
Below are the recommended typical output voltage inductor, capacitor combinations for optimized total design size.
