BU33UV7NUX
同步整流　升壓DC/DC轉換器

BU33UV7NUX是消耗電流較低的同步整流升壓DCDC轉換器，作為升壓電源，適用於使用2 CELL鹼性、鎳鎘、鎳氫電池或1 CELL鋰離子、鋰聚合物電池的產品。即使2 CELL乾電池的電壓降至1.8V，仍可提供最大500mA輸出負載。而且，BU33UV7NUX還搭載了復位IC功能（檢出：1.5V, 解除：1.9V）。BU33UV7NUX的輸出電壓固定為3.3V，如果Vin電壓超過3.3V的輸出電壓，則Vin與Vout會在內部連接。

    • The BU33UV7NUX converter provides a power supply solution for products powered by two-cell alkaline, NiCd, NiMH, one-cell Li-ion, or Li-polymer batteries. It can operate even if the input voltage drops to 0.6V. The BU33UV7NUX has a built-in reset circuit that can be set to detect reset at 1.5V (reset release voltage: 1.9V).
