Fully integrated LED driver modules from TI in chip package

Texas Instruments Incorporated (TI) has introduced two fully integrated LED driver micro-modules that eliminate the external components and complex layout placement challenges typical of LED driver designs. The 450-mA TPS92550 and TPS92551 DC/DC LED driver modules incorporate all the required power and passive circuitry into a single IC package to deliver up to 23W of power to the LED.

The 14-W TPS92550 and 23-W TPS92551 are constant current buck LED driver modules that virtually eliminate the need for power supply design resources and simplify procurement.

Key features of the modules:
1. The driver integrates an inductor, Schottky diode and few passive components.
2. LED current is adjustable from 300 mA to 450 mA
3. Robust IC package
4. Large back metal plate; operate in high ambient temperatures
5. Package: 10.16 x 9.85 x 4.57 mm
