9.2.1.2.4 Bootstrap Capacitor for the BUCK1 Controller

The BUCK1 controller requires a bootstrap capacitor. This bootstrap capacitor must be 0.1 μF. The bootstrap capacitor is located between the PH1 pin and the BOOT1 pin (see Figure 9-1). The bootstrap capacitor must be a high-quality ceramic type with X7R or X5R grade dielectric for temperature stability.
