TLC69661YBHR TI LED Driver | 24-DSBGA (1.58X2.43) | 48-Channel, 5V Output

Product Overview

The TLC69661YBHR is a 48-channel constant-current LED driver from Texas Instruments, designed for high-resolution display backlighting and automotive lighting applications. Housed in a compact 24-DSBGA (1.58x2.43mm) package, it integrates advanced features such as 16-bit PWM dimming, phase-shift control, and fault detection. The device operates from a 3.0V to 5.5V supply and provides up to 5V output per channel, with each channel capable of sinking 5-50mA constant current. Its low quiescent current (0.5mA typical) and high efficiency make it ideal for power-sensitive designs.
