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.资料下载
