Introduction
The Texas Instruments TPS75105DSKEVM-529 evaluation module (EVM) helps designers evaluate the
operation and performance of the TPS75105 low-dropout linear regulator (LDO), two-bank LED driver with
PWM dimming. The TPS75105 contains four current-regulated LED driver outputs and operates from a
2.7-V to 5.5-V input supply. The IC drives the anodes of two banks of two LEDs. Each bank is
independently enabled and can be dimmed using a PWM signal to the EN pin. The LED current is
programmed using a resistor from ISET to GND. The EVM has jumpers for both EN input pins for easy
evaluation. The LDO topology and the 9-ball chip-scale package provide a small-footprint solution for
battery-powered LED-driver applications.
