1.6A Flash LED Driver
General Description
The RT8547 is a high efficiency, high current, Boost-type flash LED driver capable of 1.6A maximum output current. It is an ideal power solution for LED photo flash applications in all single cell Lithium-ion/polymer battery operated products.
The RT8547 maintains output current regulation by switching the internal high side and low power switches switch transistors. The power switches are pulse width modulated at a fixed frequency of 2MHz. The high switching frequency allows the use of small inductor and output capacitor that makes the RT8547 being ideally suited for small battery powered applications.
