LT1934 is used for 3.3V voltage conversion output, the input voltage is 13.5V, and the output voltage is 3.3V. Refer to the typical circuit design in the manual. The measured VIN=10V, the quiescent current in the open-circuit state is 30ua-230ua, and it stays at about 40ua most of the time, which is quite different from the manual quiescent current. The following is the schematic diagram and PCB, where VIN=10V, VBOOST=7V, VSW=3.33V, VFB=1.34V are measured during the test.
