Description 描述
Your power supply problems just got SUPER SOLVED! This 3.3V Buck Converter Breakout board is great for supplying power to low voltage circuits from a single Li-Ion cell battery or USB power. This chip provides up to 600-mA load current across the entire input voltage range of 3.5 to 5.5V. Great for your portable project, we made this "pin compatible" with the LM1117-3.3V TO-220 chip so you can swap it in for better performance (90-95% efficiency!) There's also an ENable pin, tie it low to shut down the output completely.
您的電源問題剛剛超級解決！這款 3.3V 降壓轉換器分線 板非常適合透過單一鋰離子電池或 USB 電源為低壓電路供電。 該晶片在 3.5 至 5.5V 的整個輸入電壓範圍內提供高達 600mA 的負載電流。 非常適合您的便攜式項目，我們使其與 LM1117-3.3V TO-220 晶片“引腳兼容”，因此您可以將其更換以獲得更好的性能（90-95％的效率！）還有一個 ENable 引腳，將其拉低即可完全關閉輸出。
There's a 2-MHz fixed-frequency in PWM mode and PFM mode extends the battery life by reducing the current during light load or standby operation.
PWM 模式具有 2 MHz 固定頻率，而 PFM 模式可透過降低輕載或待機操作期間的電流來延長電池壽命。
Comes with a fully assembled and tested breakout board. We also include header to plug it into a breadboard.
配備完全組裝並經過測試的分線板。 我們還提供了將其插入麵包板的接頭。
