SMD 2.5-5.5 to 5V 1A Step-up Boost Converter Power Supply Module
This is a mini DC-DC step-up power module and it output fixed 5V. Using a low temperature drift 0.1% accuracy of the precision resistor£¬ even if the board temperature rise a lot£¬ resistance of the resistor changes less£¬ so it does not affect the output voltage. The greater the input voltage£¬ the greater the ability to output current. Can be directly soldered on the surface of experiment PCB board£¬ easy to solder for everyone. It is especially for Arduino£¬ smart car£¬ phone charger£¬ portable charger and other items. Features: - Module type: Non-isolated step-up module (boost); - Pins package: Both SMD and 2.54mm pin headers are available; - Input voltage: 2.5V-5VDC - Output voltage: 5VDC ± 2% - No-load current: less than 500uA - Output current: 1.5A(MAX) @input voltage is 4.2V - Continuous Current: 1A(MAX) @input voltage is 3.7V - Conversion efficiency: 88%(MAX) - Switching frequency: 1.2MHz Typical - Input and output ports: green screw terminal (3.5mm pitch) - Onboard power switch£¬ you can turn off output power. - On-board high-capacity X7R capacitors that can enhance the stability. - Great for Arduino DIY projects
