SKY81279 1.5A Single Flash LED Driver IC

 

CDI is pleased to introduce Skyworks SKY81279, a high efficiency 1.5A LED flash driver with a simple interface in a small 2 x 3 x 0.75 mm TDFN package.

The SKY81279 is ideal for LED photo flash applications with single-cell Li-ion powered products as well as driving single LEDs in flash or torch mode in handsets, tablets, digital-still cameras and LED flashlights.

The SKY81279 maintains output current regulation by switching the internal high-side and low-side switch transistors, and the transistor switches are pulse-width modulated at a fixed frequency of 2.0 MHz. The high switching frequency enables the use of a small, external inductor and output capacitor.
