Other Parts Discussed in Thread: LM5143, LM25143, LM5141

Hi TI expert,

In TI TDA4 DEMO design， LM5143 or LM5140 was used. Is this two PMIC are disigned for TDA4 platform？Is there any special parameter of these two PMIC are disgned for TDA4?

Right now these two PMIC are out of stock. If there some other PMIC or power IC recommended for TDA4 platform?

Thanks

Hi,

Pls check if LM25143 can be used.

LM5141 is one channel controller and can be backup solution

Can I change it to other one channel DCDC, because only 3.3V current is big, another 5V output current is less than 3A which can be replaced by other DCDC.

Yes, you can use converter for 3A load current.
