Part Number: BQ24630

Hello TI experts,

when I see the datasheet of BQ24630, I see typical application in figure 22, please see below;

My question is, can I replace Q1 and Q2 (connected to ADAPTER+) to load switch IC?

I think it have high voltage spec. it is not easy to replace.

If yes, can you recommend the part to replace?

Please check this issue.

Best regards,

Hi Chase,

Not really necessary to use a load switch, as the integrated ACDRV has inbuilt dead time (turn on time can be changed with RC passives as well), and there is already soft start inbuilt into converter (converter has delay before starting up). If you still want to you can take a look at load switch portfolio here: www.ti.com/.../overview.html
