JAJSFC9B September 2017 – June 2018 TPS560430
UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
The TPS560430 provides an integrated bootstrap voltage regulator. A small capacitor between the CB and SW pins provides the gate drive voltage for the high-side MOSFET. The bootstrap capacitor is refreshed when the high-side MOSFET is off and the low-side switch conducts. The recommended value of the bootstrap capacitor is 0.1 µF. A ceramic capacitor with an X7R or X5R grade dielectric with a voltage rating of 16 V or higher is recommended for stable performance over temperature and voltage.
