The Texas Instruments TPS61042DRBR is an active boost converter designed for white LED applications. It operates with an input voltage range of 1.8 V to 6 V and can provide an output voltage up to 28 V. The device features an internal 30 V switch with a maximum current rating of 500 mA, making it suitable for driving LEDs efficiently.
With a maximum switching frequency of 1000 kHz and a duty cycle up to 88%, the TPS61042DRBR offers precise brightness control using PWM or analog signals. It achieves a peak efficiency of 85% and has a low quiescent current of 38 µA typical when not under load, and a shutdown current of 0.1 µA typical. The converter is available in a compact 3 mm x 3 mm QFN-8 package, suitable for space-constrained designs.
Key features include load disconnect during shutdown and overvoltage protection. The device is designed to operate with small output capacitors down to 100 nF. Its operating temperature range is -40 °C to 85 °C.
The input voltage range is from 1.8 V to 6 V.
The maximum output voltage is 28 V.
The maximum LED current per channel is 50 mA.
The peak efficiency is 85%.
The operating temperature range is -40 °C to 85 °C.
It is available in a VSON (DRB) and QFN-8 package, measuring 3 mm x 3 mm.
