2 / 19 page DM134B 、 、 、 、DM135B 點晶科技股份有限公司 點晶科技股份有限公司 點晶科技股份有限公司 點晶科技股份有限公司 SILICON TOUCH TECHNOLOGY INC. 16-Bit Constant Current LED Drivers -1- Version : : : :A.001 Preliminary DM134B、 、 、 、DM135B 16-Bit Constant Current LED Drivers with 3.3v ~ 5v Supply Voltage General Description The DM134B、DM135B are constant current drivers specifically designed for LED display applications. The value of constant current can be varied using an external resistor. The devices include a 16-bit shift register, latches, and constant current drivers on a single Silicon CMOS chip. Features 3.3V~5V CMOS Compatible Input Maximum Clock Frequency: 25MHz (Cascade Operation) Maximum Output Voltage: 17V Package: DIP24, SOP24, SSOP24, QFN32 Package and Pin Layout: Pin layout and functionality are similar to those of the ST2221C. (Each characteristic value is different.) Constant Current Matching: (Ta = 25 °C、VDD = 5.0V) Chip-to-Chip: ± 10.0% Bit-to-Bit: DM134B: ± 4.0% @ IOUT = 30 ~ 90mA ± 6.0% @ IOUT = 20 ~ 30mA DM135B: ± 4.0% @ IOUT = 20 ~ 60mA ± 6.0% @ IOUT = 5 ~ 20mA |
