Sipex SP7616 4-Channel Low Side LED Driver Brightens Future TFT Displays



MILPITAS, Calif., March 27 // -- Sipex Corporation , a leading provider of high performance analog integrated circuits, today announced the release of the SP7616, a 4-channel low side LED driver. It is designed to drive LEDs in series from input voltages as high as 30V. Expanding Sipex's existing LED driver portfolio, the SP7616 is ideal for powering small and mid-size LCD modules that use LEDs for backlighting.

SP7616 employs a minimum amount of external components to simplify board design and minimize system cost. The SP7616 is capable of powering up to four LED strings of nine LEDs @ 60mA per string for a total of 36 LEDs. The desired LED current can be adjusted with only one external resistor, and the precision string-to-string current matching ensures consistent color temperature across the whole display. The device also features very low dropout voltage (100mV@20mA) to maximize system efficiency and avoid difficult thermal design requirements. Brightness can be adjusted by employing a PWM dimming scheme. PWM dimming allows brightness control without unwanted color shifts. Additionally, the SP7616 features built-in thermal protection which automatically adjusts LED current to prevent overheating. The SP7616 is available in a tiny 2mm x 3mm 8 pin DFN package.

"Current accuracy and efficiency are very important to LED backlighting applications," said Jason Lu, Sr. Technical Marketing Manager. "Sipex is committed to provide quality LED driver solutions like the SP7616 which designers can use to develop highly reliable, LED based backlight solutions."

Pricing and Availability

SP7616 operates from -40 degrees C to 85 degrees C temperature range. Samples are available now, and pricing begins at $1.00 in 1,000 piece quantities. Datasheets and additional information on this family and other Sipex product offerings may be found on the company web site at www.sipex.com.
