SIMPLE SWITCHER Power Converter High Efficiency 1A Step-Down Voltage Regulator With Features
Apr 1, 1. Apr 1, 2 0. Hello, I am trying to set up a switching regulator to supply 5V from a varying input source, but I am having some issues.
The regulator Lm267 I am using is the LM datasheet Under dstasheet small load for example a microcontrollerthe circuit regulates the voltage very nicely throughout the range of input voltages. As I increase the input voltage from there, the output voltage drops down to V. What could be going wrong? I have tried to follow the datasheet, and I have tried various combinations of components as given by the datasheet.
This setup should handle significantly higher output currents than I’m trying to lmm2672. Is there something from the datasheet that I have overlooked, or some other mistake I might have made?

Apr 1, 2. Apr 28, 3, It would be helpful to see a picture of the coil. Apr 1, 3. Oct 18, 3, I had a similar experience when I first got into switching regulators and used an inappropriately sized inductor, which would regulate for small loads and drop to near 0V for large ones, the inductor had fried and seemed to make contact when there wan’t much heat generated in the coil and was open when it heated up.
To be short, is your inductor properly sized? Apr 2, 4. Here are the inductors I have tried: I don’t have any better dummy load a the moment. The adjustment resistors R1 and R2 are 1.
The whole setup is made on a breadboard, but I’ve tried to keep the relevant connections as short as possible. The power is supplied by a bench power supply.
