AAT1274
1.
5A Single Flash LED Driver IC
General Description
The AAT1274 is a high-efficiency, 1.
5A high-current boost converter for LED photo flash applications.
It maintains output current regulation by switching the internal high-side and low-side switch
transistors, pulsewidth modulated at a fixed frequency of 2MHz.
The high switching frequency allows the use of a small external inductor and output capacitor, making the AAT1274 ideally suited in all single cell, Li-ion-powered applications.
Skyworks' proprietary AS2Cwire™ (Advanced Simple Serial Control™) serial digital interface is used to enable, disable, configure, and program the operation of the AAT1274.
