Single Flash LED Driver: SKY81290Source: Skyworks Solutions, Inc.
This single flash LED driver has a 2.7 V to 5.5 V input voltage range and a switching frequency of 2.0 MHz. It’s ideal for applications involving smartphones, multimedia mobile phones, LED photo flash/torch devices, and camera-enabled mobile devices.
The SKY81290 LED driver features a single channel flash output, an up to 1.2A regulated output current, up to 88% efficiency, a flash safety timer, true load disconnect, soft start and input current limit, over voltage/short circuit/over-temperature protection, and AS2Cwire single wire programming. The LED driver’s high switching frequency allows the use of a small external inductor and output capacitor – making it particularly ideal for small battery-powered applications.
