Hello Lawrence,
Overall the schematic looks OK. Please note the resistors on SRP/SRN are recommended to be 10 Ohm but you have 2 Ohm.
This device is pretty old. Have you considered a newer one like BQ24770?
Thanks,

Hi, Khalid
Thank you for review, if device load is 30w, 20V/1.5A
have any concern?
Please note: The device is not notebook, it`s for VR Charging dock.
if any, Please advise me.
Thanks,
Best regards,
Lawrence
Hello Lawrence,
Is that the output load or the input voltage? Note that this is a Buck only charger, so input voltage must be higher than output voltage.

Hi, Khalid
let me double confirm, if output load is 30W, 20V/1.5A, could workable?
as below chart
if any, Please advise me.
Thanks,
Best regards,

Hello Lawrence,
With 20V Adapter, the 20V/1.5A should be OK as it is a direct path.
