Preliminary
16-BIT CONSTANT CURRENT
LED SINK DRIVER
CMOS IC
 DESCRIPTION
The UTC L16B45A is designed for LED displays. UTC
L16B45A contains a serial buffer and data latches which convert
serial input data into parallel output format. At UTC L16B45A
output stage, sixteen regulated current ports are designed to
provide uniform and constant current sinks for driving LEDs within
a large range of V_f variations.
UTC L16B45A provides users with great flexibility and device
performance while using UTC L16B45A in their system design for
LED display applications, e.g. LED panels. Users may adjust the
output current from 3mA to 45mA through an external resistor, R_ext,
which gives users flexibility in controlling the light intensity of LEDs.
UTC L16B45A guarantees to endure maximum 17V at the output
port. The high clock frequency, 25MHz, also satisfies the system
requirements of high volume data transmission.
