Hi,我有两个需求,现在想确定芯片型号,由于TI官网芯片数量太多不好定型号。谢谢!
1、(1) 输入电压 额定电压12v,电压波动范围为8v~16V。
(2)输出电压为12V,电流2A以上。
2、(1)输入电压同上
(2)输出为3路独立地(隔离地),5v。
要求是汽车级芯片,最好有样品电路板。

Hi
LM3481-Q1/LM3488-Q1这类升压芯片做成SEPIC topy的电路也是可以的。
三路输出不共地,可以用这些芯片做成flyback, 还可以用TPS40210-Q1等。
要求1:
看一下这个链接,有原理图,BOM,PCB和测试结果。

PMP11479 is a synchronous boost power supply using the LM5122-Q1 controllers. The design accepts an input voltage of 6Vin to 16Vin, and boosts a 12Vout rail capable of sourcing 2.5A continuous current. The LM5122-Q1 has an internal current source to keep the high side FET to run at 100% duty cycle which allows a bypass operation when the input voltage is greater than the configured output voltage.
