Catalyst Semiconductor Inc. has announced its entry into a new market segment with its first white LED driver integrated circuit, the CAT32. Designed for Li-ion battery-powered systems such as cell phones, PDAs, MP3 players and digital cameras, the product operates as a switch-mode, 1.2MHz fixed-frequency, constant-current boost regulator.

The CAT32 features a load-fault protection against an open circuit, efficiency of over 80 percent, single resistor LED current programming, PWM and DC level brightness control, "zero" power shutdown, and current limiting.

Available in 6-lead SOT23 package with a maximum thickness of 1mm, and TDFN packages with 3-by-3mm and 3-by-4.9mm footprints and maximum thickness of 0.8mm, the prices of the LED driver start at 55 cents in 10,000-piece quantities.
