"These new LED driver products represent our ongoing efforts to expand our content and penetration of the automotive industry," said Ven Shan, vice president of analog products at ISSI. "Industry analysts forecast double digit growth for automotive LED lighting over the next five years, driven by its widespread use in both interior and exterior lighting applications for safety, durability and aesthetics. We are well positioned to leverage our current leadership position in memory solutions to address this exciting growth opportunity in the automotive market."ISSI's new LED drivers include a DC-DC boost switching controller with outputs up to 60V to drive multiple strings of LEDs as well as regulated current sinks with string-to-string current matching accuracy of ±1.5% to ensure uniform LCD display brightness. The IS32BL3552 supports two parallel strings of up to 360mA each, while the IS32BL3554 supports four strings of up to 180mA. For added flexibility, the sinks can be paralleled together to achieve even higher LED currents.
