TPS61042DRBR +BOM

30-V, 500-mA switch boost converter in QFN-8 for white LED applications

TPS61042DRBR General Description

The TPS61042DRBR is a highly efficient boost converter tailored for driving white LEDs with a constant current output. By utilizing an external sense resistor, the LED current can be accurately set and regulated by the feedback pin to maintain a voltage across the sense resistor. This precise control mechanism ensures consistent brightness levels for the connected LEDs. With the option to modulate LED current using a PWM signal within a frequency range of 100 Hz to 50 kHz, users can achieve dynamic lighting effects with ease. Additionally, the device features a shutdown function that disables the LEDs during downtime, preventing leakage currents and ensuring operational safety. The integrated overvoltage protection further enhances the reliability of the TPS61042DRBR by safeguarding against potential damage in the event of a fault
