Frequently Asked Questions
What switch current and output voltage does TPS61061DRBR support for LED string drive?
TPS61061DRBR provides up to 400 mA switch current and a maximum output voltage of 19 V, enabling it to drive multi-LED series strings efficiently from a single-cell Li-Ion or 3.3 V rail. This makes it practical for backlighting small TFT displays requiring 4 to 6 series white LEDs in portable electronics.
How does the 1 MHz switching frequency of TPS61061DRBR affect external component selection?
Operating at 1 MHz allows designers to use inductors as small as 4.7 µH, significantly reducing the physical size and cost of the power stage compared to lower-frequency alternatives. The higher frequency also pushes switching noise above the AM radio band, simplifying EMI compliance for consumer and industrial handheld products.
Which package does TPS61061DRBR use, and how does it impact PCB layout in portable designs?
TPS61061DRBR comes in an 8-pin SON (DRB) package measuring approximately 2 mm x 2 mm, which is one of the smallest footprints available for a boost LED driver. This compact form factor is critical for wearables, hearing aids, and thin handheld gadgets where every square millimeter of board space matters.
When is TPS61061DRBR a better fit than a linear LED driver for a 3.7 V battery-powered flashlight?
A linear driver dissipates excess voltage as heat, reducing efficiency to as low as 50% when the LED forward voltage is close to the supply. TPS61061DRBR operates as a boost converter with typical efficiency above 80%, extending battery run time significantly—an important advantage for a 3.7 V single-cell Li-Ion flashlight requiring stable 100 mA LED current as the battery voltage drops from 4.2 V to 3.0 V.
