RT8540,PDF数据表下载

RT8540 pdf资料下载The RT8540 is a high efficiency synchronous Boost converter capable of delivering up to 1.5A maximum output current. It is an ideal power solution for up to three LEDs photoflash applications in all single-cell Lithium-ion/ polymer battery powered products. The RT8540 maintains output current regulation by switching the internal high-side and low-side switch transistors. The transistor switches are pulse width modulated at a fixed frequency of 2MHz. The high switching frequency allows the use of a small inductor and output capacitor, making the RT8540 ideally suited for small battery powered applications.Datasheet pdf资料数据表下载
