Productoverzicht

TPS61042EVM-226 is a TPS61042 constant current white LED supply with PWM brightness control evaluation module. The evaluation module uses the TPS61042 boost converter to provide 20mA of bias current to a four element white LED from a 1.8V to 6V input. This evaluation module may be modified to drive more or less than four LEDs. It may also be modified to deliver a higher or lower output current to the LEDs. The evaluation module includes a CTRL pin and an ADJ pin that allows the user to dim the LEDs. The LEDs may be dimmed using either an analog or a PWM dimming scheme. The evaluation module is configured as a constant current supply. Current regulation is accomplished by regulating the voltage across a current sense resistor. The evaluation module does not operate correctly unless a load is present.
  • TPS61042 has input voltage range from 1.8V to 6V
  • Current source with overvoltage protection
  • Switching frequency is up to 1MHz
  • LED current can be pulsed by applying PWM signal, to control LED brightness
  • Disconnects LEDs during shutdown
