We run a test with input voltage higher than output and the silicon got very hot . Can you explain this power dissipation. Thanks a lot!
Test condition:
Vin = (12V);
Set Tps61088 Vout is 9V,but actual Vout is 11.4V;
Iout = 0.5A;
Dear engineer :
We will use this chip max input voltage about 13.2V.so a bit worry this point.
We have the following questions please help solve:
After the test we do before, we find when the input is higher than 12V, the output will have a voltage drop…
Other Parts Discussed in Thread: BQ24295 尊敬的TI工程师您好:
我公司在生产一款带有3个无刷直流电机的产品,一节18650供电,电源管理芯片为 bq24295,然后由TPS61088生压到8v给电机供电,但是当三个电机运行到特定相对方位时整个系统就会掉电,图分别是原理图,layout和输出电压电流波形
