Taiwan PTC to Showcase LED Driver and Dimming Controller Lighting Solution ICs at FPD International & Green Device Exhibition

Taiwan fabless IC design company Princeton Technology Corp. (PTC) will showcase its LED driver and dimming controller lighting solution ICs on November 10-12, 2010 at the FPD International & Green Device Exhibition.

The demonstration will include 650V multifunction electronic ballast driver ICs (PT56XX series), high power LED driver ICs (PT69XX series) for LED backlighting, and the CC driver ICs (PT67XX series) for billboard display applications.

The PT56XX electronic ballast driver ICs include the dimming controller series and the ballast series.  The dimming controller ICs are suitable for various types of dimming applications such as remote, VR, 3-way switching, normal switching, and normal switching with linear dimming.  The ballast ICs integrate more functions, including security protection, APFC, 650V half-bridge high-side driver, and support for multi-lamp applications.

The PT6905, PT6910, and PT6920 high power LED driver ICs are intended for low voltage LED lighting applications such as decorative and emergency lighting.  Each IC provides protection functions and is housed in a small size package (SOT89).  Both the PT6905 and PT6910 integrate a 40V/1.2A MOS switch, while the PT6920 integrates a 60V/1.2A MOS switch.  With the PT6905’s built-in three-stage dimming control, a normal switch dimming function may be realized.

For car LED lighting, the PT6912 high power LED driver IC integrates a 40V/350mA MOS switch and various protection functions. Operation at 2MHz frequency prevents un-wanted interference to radio frequency circuitry.  The PT6970, PT6971, and PT6975 are intended for LED back-lighting applications. 
 
The PT6726 is a 16-channel, constant current driver IC suitable for LED billboard applications.  The PT6726 includes a serial buffer for data latch function, and its output pins are guaranteed capable of supporting voltages up to 17V.  With 5V LED voltage supply, its output can cascade 1 to 2 LEDs.  The PT6726 can control LED luminance not only by current magnitude, but also by PWM cycling rate.  Its output PWM pulse width may be as low as 100ns, which can satisfy the high speed PWM demands for controlling luminance and hue.
