Thank you for your patience.
LM25185 is a PDS Flyback converter that has an integrated 42V/1.5A. The power that you need to deliver is 170V*0.6A+12V*0.5A=108W. To be able to deliver that power with a VIN=9V-16V, you need a high current MOSFET at the primary…
Other Parts Discussed in Thread: TPS53640A 附件为TPS53640A芯片手册以及仿真器读出的相应寄存器的值。
生产出来的板卡,该电源有时候加电的时候并不输出,同时读出了输出时候的寄存器以及不输出时候的寄存器值,在表格中有记录。
想请相应的工程师帮忙看看是什么问题引起的?
谢谢了!
供应商那边联系技术支持已经没辙了。只靠论坛的大神了。
