Product Announcement from Skyworks Solutions, Inc.
Skyworks is pleased to introduce the SKY81279, a high-efficiency flash driver for LED photo flash/torch, camera-enabled mobile devices, smartphones, digital-still cameras and multimedia mobile-phone solutions. The 1.5 A LED SKY81279 features a simple interface and is housed in a compact 2 x 3 x 0.75 mm TDFN package. It is ideal for applications with single-cell, Li-ion powered products as well as single LEDs in flash or torch mode in handsets, tablets and flashlights. It 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 MHz. The high-switching frequency enables the use of a small, external inductor and output capacitor.
