Overview

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.
