Please let me know about following points of TPS53353.
・VBST-pin: Boot resister
①Please let me know what meaning of boot resister (R9)?
②The chip-size of R9 will "1005", is it no ploblem?
③Customer will change resister value: 2Ω → 2.2Ω, is it no pleblem?
・VDD-pin
④VDD-input connects C4:4.7μF capacitor, why a little big capacitor?
Is VDD sensitive in noise?
⑤If VDD is 12V (same as Vin), VDD will connect to Vin line, is it no ploblem?
⑥If VDD is 5V (differ to Vin), is there have sequence timing of Vin and VDD?
Best regards,
Satoshi
