Other Parts Discussed in Thread: LM5164, LM5169
Hello
Im currently using the LM5164 to convert a 48v battery to 13v. While in the normal input voltage range, the input current consumption is around 800uA. However, when the input voltage drops below my 28V UVLO threshold, the output of the LM5164 drops to 2.4V and the input current increases to 1.4mA. In this state, the LM5164 becomes noticeably hotter. The EN/UVLO pin voltage is around 1V.
any feedback would be appreciated, currently this circuit is unusable with this behavior.
