Product Overview

The TPS75105DSKEVM-529 evaluation module is a fully assembled and tested circuit for evaluating the TPS75105 low dropout, two bank LED Driver. This EVM demonstrates the TI's TPS75105 low dropout, two bank LED driver with PWM brightness control. This board drives 4 LEDs at a constant 5mA current per LED and is powered from a 2.7V to 5.5V source. The TPS75105 LDO matching LED current source is optimised for low power keypad and navigation pad LED backlighting applications. The device provides a constant current to up to four unmatched LEDs organized in two banks of two LEDs each in a common cathode topology. Without an external resistor, the current source defaults to factory-programmable, preset current level with ±0.5% accuracy. An optional external resistor can be used to set initial brightness to user programmable values with higher accuracy. Brightness can be varied from off to full brightness by inputting a pulse width modulation (PWM) signal on each Enable pin.
  • Regulated Output Current with 2% LED to LED Matching
  • Drives up to Four LEDs at 25mA Each in a Common Cathode Topology
  • 28mV Typical Dropout Voltage Extends Usable Supply Range in Lithium Ion Battery Applications
  • Brightness Control Using PWM Signals
  • Two 2-LED Banks with Independent Enable and PWM Brightness Control per Bank
  • No Internal Switching Signals - Eliminates EMI
  • Default LED Current Eliminates External Components
  • Over Current and Over Temperature Protection
