DATA SHEET AAT1290 1.5A Step-Up Current Regulator for Flash LEDs General Description The AAT1290 is a high-efficiency, high-current boost converter capable of 1.5A typical output current. It is an ideal power solution for LED photo flash applications in all single cell Li-ion powered products. The AAT1290 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 hig.

DATA SHEET AAT1290 1.5A Step-Up Current Regulator for Flash LEDs General Description The AAT1290 is a high-efficiency, high-current boost converter capable of 1.5A typical output current. It is an ideal power solution for LED photo flash applications in all single cell Li-ion powered products. The AAT1290 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 AAT1290 ideally suited for small battery-powered applications. Skyworks' proprietary AS2Cwire™ (Advanced Simple Serial Control™) serial digital interface is used to enable, disable, configure, and program the operation of the AAT1290. Using the AS2Cwire interface, the movie-mode current level for the LED, the safety timer delay, and the flash-to-movie-mode current ratio can be programmed to one of 16 le.
