AAT1282
2A Driver for High Intensity LED Camera Flash
General Description
The AAT1282 is a high-efficiency, high-current step-up converter capable of 2A maximum output current.
It is an ideal power solution for LED photo flash applications in all single cell Li-ion powered products.
The AAT1282 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 AAT1282 ideally suited for small battery-powered applications.
