•

Output Current Adjusted By External Resistor

The TLC592x-Q1 Constant-Current LED Sink Drivers

•

Constant Output Current Range: 5 mA to 120 mA

is designed to work alone or cascaded. Because

Constant Output Current Invariant to Load Voltage

each output is independently controlled, they can be

programmed to be on or off by the user. The high

LED voltage (VLED) allows for the use of a single

LED per output or multiple LEDs on a single string.

Detection

With independently controlled outputs supplied with
