Fremont, Calif.Exar Corp. has released its first in a family of high power boost controllers, the SP7606, for use in powering large LED arrays.
When used together with the SP7615 or SP7616, the SP7606 boost controller reduces component count by four devices, shrinks external component size, and reduces the package from a 3x3mm to a 2x3mm DFN.
It can also be used for general DC/DC conversion in boost, flyback, Cuk, and SEPIC configurations. The most common market for large arrays of LEDs is LCD display backlighting; however it can also be used for the growing conversion market from incandescent and florescent to LED lighting systems.
The SP7606 is an internally compensated 1.2MHz boost controller suitable for driving any number of topologies using a low side switch and the high frequency and internal compensation ensure a small solution size in all applications.
The device is in a Pb-free, 2x3mm 8-pin DFN package and operates over the -40°C to +125°C temperature range.
Pricing: $0.85 each in 1,000-unit quantities.
Availability: Samples are available now.
