PRODUCTION DATA.
For regulator stability, a 1-μF capacitor is required to be connected from BP to GND. In some applications using higher gate charge MOSFETs, a larger capacitor is required for noise suppression. For a total gate charge of both the high-side and low-side MOSFETs greater than 20 nC, a 2.2-μF or larger capacitor is recommended.
