Features:1. Wide input range of 3–20V, compatible with lithium batteries, solar panels, and storage batteries2. Continuously adjustable output voltage of 1.2–18V, precisely meeting the needs of various applications3. Suitable for battery voltage regulation, solar power regulation, and unmanned power supply applications4. Built-in protection mechanisms including current limiting, soft start, short-circuit protection, and over-temperature protection5. Compact PCB design supports embedded installation and is easy to useProduct SpecificationsProduct Name: DC-DC Non-Isolated Automatic Buck-Boost Voltage Regulator ModuleInput Voltage: 3V–20VOutput Voltage: Adjustable between 1.2V and 18VMaximum Current: 3A (Max); determined by input current in boost mode and by output current in buck modeMaximum Power: 24W (Max)Operating Temperature: Industrial grade –40°C to +85°CSwitching Frequency: 450 kHzHigh Efficiency, Low RippleEnable Function (EN): Low level turns the output off; high level turns it on. Default state is on.Precautions1. Connect the module to the power supply first, then apply power. Remember this! Remember this! (High voltages can cause sparks, which may result in scorched pads at best or a burned-out chip at worst.)2. It is not recommended to connect inductive loads to the output, such as fans, motors, or electric motors. Inductive loads draw high inrush current during startup and generate back-EMF when stopping; alternatively, connect an electrolytic capacitor in parallel across the output terminals.3. When the input voltage is less than 4 V, efficiency decreases and load-carrying capacity is reduced.Package ContentsBuck-Boost Module × 1
