Part Number: TPS61500
Hi, I have issue with TPS61500 it stop switching when input voltage is lower than 4.2V, but works perfect on higher voltages. In attach i collect some waveforms and schematic. Load is 4 LEDs, with 12V on them and only 300 mA of current. Do you have any idea, why my design doesn't work?
