TOSHIBA T B 6 2 7 2 5 P / F / FN TOSHIBA Bi-CMOS INTEGRATED CIRCIUTS SILICON MONOLITHIC TB62725P/F/FN 8BIT CONSTANT CURRENT LED DRIVER OF OPERATING VOLTAGE 3.3V TB62725 series is the constant current driver designed for LED and the LED display. Output current value is set with one resistor with the outside. Then, all the output becomes the about same current. This driver builds in the constant current output of eight bits, the shift register of eight bits, the latch of eight bits and gate circuit. This driver is designed by using the BI-CMOS process.
