16 Channel Constant Current Led Sink Driver

At the tlc592x output stage 16 regulated current ports provide uniform and constant current for driving leds within a wide range of v f forward voltage variations.

16 channel constant current led sink driver.

The tlc592x is designed for led displays and led lighting applications with open load shorted load and over temperature detection and constant current control. The tlc592x contains a 16 bit shift register and data latches which convert serial input data into parallel output format. At the tlc592x output stage 16 regulated current ports provide uniform and constant current for driving leds within a wide range of v f forward voltage variations. Low output voltage operation on the led channels as low as 0 4 v for 2 to 100 ma led current allows for more power efficient designs.

Each channel can be turned on off by writing serial data to an internal register. Users can adjust the output current from 5 ma to 120 ma through an external resistor r. 16 channel constant current driver for led billboard and other general display applications. Output stage 16 regulated current ports provide uniform and constant current for driving leds within a wide range of vf forward voltage variations.

Led channel currents are programmed together via an external rset resistor. The constant current value of all 16 channels is set by a single external resistor. Used in systems designed for led display applications e g led panels tlc5926 tlc5927 provides great flexibility and device performance. The cat4016 is a 16 channel constant current driver for led billboard and other general display applications.
