Frequently Asked Questions
What input voltage range does the TPS6286810CRQYR support, and how does that suit USB-C power delivery designs?
The TPS6286810CRQYR accepts a 2.4 V to 5.5 V input, covering the full 5 V USB standard and single-cell Li-ion range of roughly 3.0 V to 4.2 V. This makes it ideal for USB-C bus-powered boards where the rail can vary by more than 1 V under load transients, ensuring a stable regulated output throughout the full charge cycle with up to 4 A of output current.
How does the I²C interface on the TPS6286810CRQYR benefit dynamic voltage scaling in FPGA or SoC power trees?
The I²C interface lets a host processor adjust the output voltage on-the-fly without changing external resistors, enabling dynamic voltage scaling (DVS) for FPGAs and SoCs that require multiple operating points—for example stepping from 1.0 V at idle to 1.2 V at peak performance. This reduces design complexity compared to discrete resistor dividers and allows firmware-controlled power sequencing across 8-bit programmable steps within the 2.4 V to 5.5 V input window.
When should a designer choose the TPS6286810CRQYR over a fixed-voltage 4-A buck converter for a battery-powered IoT device?
Choose the TPS6286810CRQYR when the end product needs field-reconfigurable output voltage or supports multiple hardware revisions that share a PCB, since the I²C programmable output eliminates costly board respins. Its PFM mode also extends battery life in IoT nodes by reducing switching losses at light loads below roughly 200 mA, and the 1.5 mm x 2.5 mm QFN-9 footprint saves significant board area compared to SOT-23-6 or larger fixed-voltage alternatives.
What switching frequency and control topology does the TPS6286810CRQYR use, and what does that mean for output filter sizing?
The TPS6286810CRQYR uses current-mode pulse-width modulation (PWM) switching, which provides inherent cycle-by-cycle current limiting and faster load-transient response compared to voltage-mode control. Current-mode topology allows a smaller output inductor—typically 1 µH to 4.7 µH—and a low-ESR ceramic capacitor in the 10 µF to 47 µF range to meet transient specs, keeping the overall solution size well within the 1.5 mm x 2.5 mm converter footprint.
