SKY81296

2.4 A / 2 A Dual Independent Flash LED Driver with TrueFlash™

Please note: this product is being discontinued and is not recommended for new designs.

The SKY81296 with TrueFlash™ is a high-efficiency, 2.4 A/2 A high-current boost converter with two independently programmable constant current outputs. By offering completely independent control of the two LEDs, the SKY81296 enables camera system engineers to implement sophisticated flash management algorithms that enhance image quality. The device is intended for LED photo flash applications in all single-cell Li-ion powered portable products.
