Frequently Asked Questions
What is the maximum switch voltage and current rating of the TPS61042DRBT?
The TPS61042DRBT supports a maximum switch voltage of 30 V and a maximum switch current of 500 mA. These ratings make it suitable for driving series LED strings requiring up to 30 V forward voltage, covering configurations of up to 5 white LEDs in series from a single-cell Li-Ion input of 2.7 V to 4.2 V.
Which portable backlight applications are best served by TPS61042DRBT?
This device is ideal for LCD backlight drivers in smartphones, e-readers, and portable medical equipment where a compact boost converter operating from 2.7 V to 5.5 V is needed. Its single-channel architecture and SOT-23 package suit constrained PCB layouts under 10 mm² while delivering regulated LED currents up to approximately 80 mA at full duty cycle.
How does TPS61042DRBT achieve PWM dimming and what frequency is supported?
TPS61042DRBT supports direct PWM dimming via the CTRL pin, allowing duty cycles from below 1% to 100% for smooth brightness control. Supported PWM frequencies typically range from 100 Hz to 50 kHz. This enables flicker-free dimming at 8-bit resolution steps when driven from a microcontroller GPIO at 3.3 V or 5 V logic levels.
When is TPS61042DRBT a cost-effective alternative to a full WLED driver IC?
TPS61042DRBT provides a lower-cost solution for single-channel, 1–5 LED string applications compared to multi-channel WLED drivers such as TPS61195. With only external resistors, an inductor, and a capacitor needed, the BOM count stays under 8 components. Its VOUT regulation accuracy of ±2% eliminates the need for a separate feedback circuit in most single-string designs.
