BQ24650: PCB Design guidelines; more details request.

SWAROOP R SADARJOSHI

Part Number: BQ24650

Hello,

I am employing BQ24650 as a solar charge controller for my application. I operating BQ24650 at Vbat=4.2V and Icharge=2.6A.

I am designing a PCB for the above said configurations. In the data sheet of BQ24650 under section "11 Layout" it doesn’t

give detailed about PCB design consideration, like suitable number of layers etc.

Q1. Can anyone provide me elaborate resource on designing a PCB for converter?

Q2. Is there any detailed documentation available from TI regarding converter PCB design?

Thanks and regards!

We recommend to use 4 layer PCB and use gnd layer as noise shelding. Please use the EVM layout as example. If you follow the bq24650 datasheet layout guideline closely, it should be sufficient. We do not have a specific document for this, but if you do a search there are a lot of general guide for converter layout
