5V DC Switchmode Plugpack Supplied with a fixed positive to tip 2.1mm DC jack. Compact design with high current regulated output. Energy authority approved. MEPS approved. 5V DC @ 2A Dimensions: 75L x 42W x 40D mm

The S7V8F5 switching step-up/step-down regulator efficiently produces a fixed 5 V output from input voltages between 2.7 V and 11.8 V. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below the regulated voltage. The compact (0.45″ × 0.65″) module has a typical efficiency of over 90% and can deliver 500 mA to 1 A across most of the input voltage range.

This is a small DC - DC boost module that integrates a PFM DC-DC boost control chip. It can convert a 0.9 ~ 5v power source to standard 5V, making it capable of supplying power to an Arduino microcontroller and other small electronic devices that use a 5v input. The maximum output current is up to 500 ~ 600 mA. There are two power input ports, PH2.0 and KF235-3.81-2P which are compatible with DFRobot's 3.7 V lithium battery.
