Features 1. Supports wide input range of 7–31V, compatible with various batteries and power sources 2. Selectable 5V/12V output to meet diverse load voltage requirements 3. High-performance circuit design ensures stable and reliable output 4. Compact size and lightweight for easy integration into various devices 5. Built-in output short-circuit protection and over-temperature protection Parameter Operating Voltage: 7–31V (must exceed output voltage by at least 1V) Maximum 3.5A Current Output 2mA Quiescent Current Up to 94% Conversion Efficiency High-Efficiency Synchronous Mini Design Output Short-Circuit Protection Built-in Over-Temperature Protection Product Introduction Compared to similar products in the same price range, our product offers significant advantages in size and efficiency. It also supports up to 36V voltage tolerance, enabling it to handle more complex applications. With a maximum output of 3.5A, it can sustain over 3A at 5V and deliver 2.5A at 12V—performance that stands out in its price category. Precautions 1. Input voltage must exceed output voltage. Maintain a voltage differential of at least 1V for optimal performance. Do not reverse polarity; doing so will burn the board. 2. Disconnect power before wiring to prevent sparking at high voltages, which risks damaging or shorting the chip. 3. Use sufficiently thick wiring to handle the rated current. 4. Protect inductive loads to prevent excessive back EMF exceeding the chip's tolerance. 5. Higher power usage approaches the maximum current rating, increasing heat generation. Ensure adequate heat dissipation during operation. 6. Without external cooling, continuous operating current should remain below 2.5A. Exceeding this requires additional cooling to prevent thermal shutdown. 7. Recommended operating voltage is below 30V. If supply voltage is unstable, voltage spikes exceeding 30V may trigger internal overvoltage protection. Maintain a margin for stable operation. Package include Module*1 label:yes
