Hello,
I’m designing a circuit with an L5973D switching controller to give 3.8 v and am facing a peculiar problem. The circuit is as per the design reference in the datasheet and the feedback resistors are given to give 3.8 v affair (10K and 4.7 K). originally, I get 3.8 v. But while leaving the circuit connected, it starts inching up about 10mV every 10 twinkles or so. likewise, powering down the circuit and also back over doesn’t beget it to give 3.8 v again. Wondering what is going on.
