The TPS75100 contains four, current-regulated, LED driver outputs and operates from a2.7 V to 5.5 V input supply. The IC drives the anodes of two banks of two LEDs. Each bank is enabled independently 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 LEDdriver applications.
