Product Overview
The TLC59283 is a Texas Instruments 16-channel constant-current LED driver for LED systems using OUT0 through OUT15 as sink outputs. Each channel supports individual on/off control through the device serial communications protocol, with SCLK operation specified up to 35 MHz across the 3 to 5.5 V VCC range.
The output stage supports LED power supply or output drive voltage up to 10 V under recommended operating conditions, with an absolute maximum OUT pin range of -0.3 to 11 V. Constant-current operation is programmed by an external resistor between IREF and GND using the stated ideal current formula, IOUT(IDEAL) = 43.8 × 1.208 V / RIREF.
Electrical limits include 2 to 35 mA sink current for 3 V <= VCC <= 3.6 V and 2 to 45 mA for 3.6 V < VCC <= 5.5 V. Package options include DB (SSOP-24), DBQ (QSOP-24), and RGE (QFN-24). Thermal resistance is specified as 91.5 °C/W for DBQ and 42.9 °C/W for RGE.
