SNVSCW3 November 2024 LM644A2-Q1
PRODUCTION DATA
The LM644A2-Q1 requires a bootstrap capacitor connected between the CBOOT pin and the SW pin. This capacitor stores energy which is used to supply the gate drivers for the power MOSFETs. TI recommends a high-quality, 100nF ceramic capacitor with a rating of at least 10V.
