This DC-DC buck-mode power module offers an input voltage range of 8V - 28V and a fixed 5V/3A output. With a working frequency of up to 0.5MHz, it features a high conversion rate and a compact size, making it easy to integrate. It provides a stable output voltage, suitable for high - requirement scenarios and long - term use without voltage drift. You can pair it with high - capacity and high - voltage batteries to create DIY mobile power sources or embed it in your projects for multiple power options. Its small size, stable performance, and wide voltage range make it ideal for various DIY applications. Applications include powering controller main - boards, DIY current sources, floodlights, DIY toy cars, communication devices, and digital radios. Specification details: Input Voltage: 8 - 28Vdc; Output Voltage: 5V; Output Accuracy: ±0.1V; Maximum Output Peak Current: 3A; Full - Load Output Ripple: Vpp < 50mV; No - Load Current: IQ 0.5mA; No Switch - Off Function; Operating Temperature: - 20℃ - +85℃; Operating Humidity: 20% - 90% relative humidity, no condensation; Storage Temperature: - 40℃ - +125℃; Installation Method: Chip - mounting; Without Isolation; Service Life: 30000h; Dimension: 16.5×22mm/0.65×0.87inch. Note: Keep the input voltage within 28V. Avoid long - term load current at 3A or above to prevent affecting the module's lifespan or causing burnout. Increase the minimum input voltage if the load current is high to ensure normal operation.
Using this power module is quite straightforward. First, make sure the input voltage from your power source is within the 8 - 28V range. Connect the module to your device or project, and it will start providing a stable 5V output at up to 3A. For DIY projects, you can pair it with high - capacity batteries to create your own mobile power source. Just be careful not to let the load current stay at 3A or higher for a long time, as this can damage the module. If you're using it with a high - load device, raise the minimum input voltage to keep everything running smoothly. When it comes to maintenance, keep the module in an environment with a temperature between - 20℃ and +85℃ and a relative humidity of 20% - 90% without condensation. Store it in a place where the temperature is between - 40℃ and +125℃. With proper use and storage, this module can serve you well for up to 30000 hours.
