Features:1. Ultra-wide input range of 11–100 V, compatible with most power supply systems2. Peak current output of 2.5 A, with robust load-handling capability3. Selectable 5 V or 12 V output to meet the needs of different devices4. Utilizes high-frequency capacitors paired with large inductors for low ripple and high efficiency5. Built-in over-temperature protection and output short-circuit protection, suitable for harsh environments6. Primarily used for high-voltage step-down, battery power supply, industrial/automotive electronics, and fast-charging applicationsProduct SpecificationsInput Voltage: DC 11–100 V (maximum input 100 V)Output Current: 2.5 A peakQuiescent Current: 1–7 mAConversion Efficiency: Up to 92%Switching Frequency: 140 kHzOperating Temperature: –40°C to +85°COutput includes TVS and fuseModule InterfacesIN+: DC input positive terminal, 11 V–100 V (must be at least 6 V higher than the output)GND: DC input and output negative terminal; input and output negative terminals are connectedOUT+: DC output positive terminalEN: Buck enable; default is floating (enabled); pulling the pin below 1 V turns it off; 2.4–6 V enables buck conversionPrecautions1. The input voltage must be higher than the output voltage; ideally, maintain a voltage difference of at least 6V (for products with specified operating voltages, follow the actual specifications). Do not reverse the input polarity, as this will burn out the board.2. It is best to disconnect the power supply when wiring; otherwise, sparks may occur at high voltages, posing a risk of damaging or breaking down the chip. Input capacitors may explode if the positive and negative terminals are reversed.3. Do not use wires that are too thin; ensure the wires can handle the corresponding current.4. Do not use with inductive loads, such as motors, relays, or other devices with coils. If connecting to inductive loads, implement proper protection to prevent excessive back-EMF from exceeding the chip’s tolerance range.5. The higher the power drawn by the module and the closer the current is to the maximum current rating, the greater the heat generation will be. Ensure adequate heat dissipation during use.6. Without external cooling, continuous current should be kept below 2A. If the current exceeds 2A, additional cooling is required; otherwise, the output will trigger thermal protection.7. The operating voltage should be kept below 100V. If the supply voltage is unstable, voltage spikes exceeding 100V will trigger the chip’s internal overvoltage protection. To ensure stable operation, allow for an appropriate margin.Package ContentsBuck Module *1
