Title: Troubles about Project Based on LM5008MM
Post by lingling on Jul 3^rd, 2017, 1:04am

I’m designing a project using LM5008MM ( LM5008MM PDF )while I met a problem that the working power is 23V providing by battery,the voltage is about 72V and I have design ignortion signal in order to realize low-power comsumption. It continued to control DC-DC to work by IO of MCU. Now my problem is:
Controlling diode by IO of MCU while the input power connect the base of diode by a 1M resistance. In another word, IO pot connect IO of MCU by 1M resistance. Will the IO be break out here?
