The AAT1272IWO-T1 from Skyworks Solutions is a 1.5A step-up current regulator ideal for LED photo flash applications in single-cell Li-ion powered products. It operates with an input voltage range of 2.7V to 5.5V and features a high switching frequency of 2MHz, allowing for small inductor and capacitor sizes.
This LED driver IC provides dual channel output, capable of delivering up to 1.5A total regulated output current (750mA per channel). It includes an industry-standard I2C serial interface for enabling, disabling, and setting movie-mode current with up to 16 settings. A separate Flash Enable input initiates flash operation and a user-programmable safety timer.
The AAT1272IWO-T1 is housed in a Pb-free, thermally-enhanced 14-pin 3x3mm TDFN package. It offers features such as over-voltage, short-circuit, and over-temperature protection, with a shutdown current of less than 1.0 μA. The device achieves up to 85% efficiency with a small 1 μH inductor.
Applications include digital still cameras, LED photo flash/torch, mobile handsets, MP3 players, PDAs, and notebook PCs.
