3 Description
The TLC59025 device is designed for LED displays
and LED lighting applications. The TLC59025
contains a 16-bit shift register and data latches, which
convert serial input data into parallel output format. At
the TLC59025 output stage, 16 regulated-current
ports provide uniform and constant current for driving
LEDs within a wide range of VF variations. Used in
system design for LED display applications (for
example, LED panels), the TLC59025 provides great
flexibility and device performance. Users can adjust
the output current from 3 mA to 45 mA through an
external resistor, Rext, which gives flexibility in
controlling the light intensity of LEDs. TLC59025 is
designed for up to 17 V at the output port. The high
clock frequency, 30 MHz, also satisfies the system
requirements of high-volume data transmission.
The serial data is transferred into TLC59025 through
SDI, shifted in the shift register, and transferred out
through SDO. LE can latch the serial data in the shift
register to the output latch. OE enables the output
drivers to sink current.
