Features 1.Constant Voltage Output: The conventional BOOST fully integrated constant voltage output solution is adopted, and the internal integrated MOSFET has stable performance. The TO263‑5L standard packaging is suitable for boost applications within 30w. 2.Wide Voltage Input & Output Voltage Adjustable: Wide voltage range input, input voltage up to 35V, adjustable output voltage, up to 40V. 3.Multiple Protection Functions: Built‑in over temperature protection, over current protection, a full set of reliability protection circuits, high reliability. 4.High System Conversion Efficiency: The system conversion efficiency can reach more than 90%, which is convenient for thermal design. 5.How To Use: Connect the power supply (3-35V), the power indicator light is on, and the module works normally. Adjust the blue potentiometer knob (generally turn counterclockwise to boost, clockwise to decrease) and use a multimeter to monitor the output voltage until it reaches the required voltage.
