The SparkFun 5V/1A LiPo Charger/Booster is a no-nonsense circuit for generating one amp from a Lithium Polymer battery at 5V. This LiPo charger is a very economical choice that is equipped with a simple booster circuit utilizing the PAM2401 IC, and includes protection diodes so you can run multiple cells in series for an extra kick. While the booster circuit is in operation, this board can draw more current the lower the input voltage, making it perfect to deliver a strong charge in a small amount of time.

The circuit is constructed by feeding an MCP73831 charge controller IC to the LiPo port, and to the input of a PAM2401 boost controller. Multiple connection types are provided for the battery, charge source and switch to allow flexibility of application, and two LEDs provide feedback on system status. If you need more than 5V out of your project, the SparkFun LiPo Charger/Boosters can also be daisy-chained together to get a bigger bang for your buck.

Note: This is not a direct replacement for the SparkFun Power Cell, as it uses a different IC. Also, this board does not possess any undervoltage or other battery protection features, so we do recommend that you use it only with batteries with a built-in protection circuit.

SparkFun 5V / 1A LiPo充電器/增強器是一種不用廢話的電路,用於在5V時從鋰聚合物電池產生一個放大器。該LiPo充電器是一個非常經濟的選擇,配備了使用PAM2401 IC的簡單升壓電路,並且包括保護二極管,以便您可以串聯運行多個電池,以增加額外的衝擊。當升壓電路運行時,該板可以吸入更多的電流,輸入電壓越低,使其在少量時間內提供強電荷是完美的。

該電路是通過將MCP73831充電控制器IC饋送到LiPo端口和PAM2401升壓控制器的輸入來構建的。為電池,充電源和開關提供多種連接類型,以實現應用的靈活性,兩個LED可提供有關係統狀態的反饋。如果您的項目需要超過5V,SparkFun LiPo充電器/ Boosters也可以通過菊花鏈連接起來,以獲得更大的爆炸。

注意:這不是SparkFun Power Cell的直接替代品,因為它使用不同的IC。此外,該板不具有任何欠壓或其他電池保護功能,因此我們建議您僅使用帶有內置保護電路的電池。
