PRODUCTION DATA
The device has three integrated boot regulators and requires a small ceramic capacitor between the BST and LX pin to provide the gate drive voltage for the high-side MOSFET. The value of the ceramic capacitor should be 0.047 μF. TI recommends a ceramic capacitor with an X7R or X5R grade dielectric because of the stable characteristics over temperature and voltage.
