This is an outstanding DC-DC buck-mode power module. It has an input voltage range from 5.5V to 28V and provides a fixed 3.3V output at 3A. With a working frequency up to 0.5MHz, it offers high conversion efficiency and comes in a tiny body, making it easy to embed in various projects. The output voltage is extremely stable, capable of long - term operation without voltage shift, which is ideal for high - requirement applications. It can be paired with high - capacity and high - voltage batteries for DIY mobile power projects. Also, it can be integrated into different projects to offer multiple power choices. Features include small size, stable performance, and a wide voltage range suitable for a variety of DIY applications. Applications are diverse, such as powering controller main - boards, DIY current sources, floodlights, DIY toy cars, communication devices, and digital radios. Specification details: Input Voltage: 5.5 - 28Vdc; Output Voltage: 3.3V; Output Accuracy: ±0.1V; Maximum Output Peak Current: 3A; Full - Load Output Ripple: Vpp < 50mV; No - Load Current: IQ 0.5mA; Switch - Off Function: Not Support; Operating Temperature: - 20℃ to + 85℃; Operating Humidity: 20% - 90% relative humidity, no condensation; Storage Temperature: - 40℃ to + 125℃; Installation Method: Chip - mounting; Without Isolation; Service Life: 30000h; Dimension: 16.5×22mm/0.65×0.87inch. Note: The input voltage must be within 28V. Do not let the load current stay at 3A or above for a long time as it may affect the module's lifespan and even cause burnout. If the load current is high, increase the minimum input voltage to ensure normal operation.
Using this power module is quite simple. First, make sure the input voltage is within the 5.5 - 28V range. Then connect it to your project according to the installation method of chip - mounting. You can use it to power different devices like controller main - boards or create DIY mobile powers with high - capacity batteries. When using, pay attention to the load current. Don't let it stay at 3A or above for a long time, as this can damage the module. If the load current is high, raise the minimum input voltage to keep it working properly. For maintenance, store the module in a place with a temperature between - 40℃ and + 125℃ and humidity between 20% and 90% without condensation. This will help ensure a long service life of up to 30000 hours.
