Current Drivers Boost Efficiency Of LED Signs

The STP16CPP05, STP16CPPS05, STP16DPP05, and STP16DPPS05 LED drivers with automatic power saving enable LED signage to deliver better, high-resolution viewing by ensuring consistent brightness. The chips supply 16 LED channels with currents from 3 mA to 40 mA with a bit-to-bit accuracy within ±1% and a ±2% current matching from chip to chip. Optional features include automatic power saving that allows the drivers to turn off independently when no drive data is available and LED-error detection (short circuit or open circuit). Prices start from $0.70 each/1,000. STMICROELECTRONICS, Lexington, MA. (888) 787-3550.
