BOOT
Upper MOS transistor boot strap capacitance
connection pin
Connect the boot capacitance of about 0.022
μF
between SW pins
To protect the SW pin’s absolute maximum rating,
to ensure stable operation, and to eliminate
noise, the boot capacitance serial resistance
(about 100
Ω) Rb proves effective.
