Considerations for the design
During use with VIN = 12V or less, the boot strap voltage may become deficient due to intermittent operation at no load,
resulting in failure of normal operation. In this case, insert a resistance of about 500
Ω between VOUT and GND and
avoid the intermittent operation mode during use.
Insertion of serial beads in the Schottky diode for removal of noise may cause generation of the negative voltage
deviating from the absolute maximum rating at the SW pin, resulting in failure of normal operation. In such an event, do
not insert beads as above described and, instead, remove noise by means of the BOOT resistance Rb.
