Key Differentiators
- 4A output current in a tiny 2mm x 3mm package (vs TPS62811QWRWYRQ1 (3A))
- AEC-Q100 automotive qualification (vs TPS62810QWRWYRQ1 (non-Q1))
- Wettable flank package for AOI inspection (vs TPS62811QWRWYRQ1 (non-wettable))
Design Notes
Place the input capacitor (10uF) and output capacitor (22uF) as close as possible to the VIN and VOUT pins, respectively. Use a solid ground plane underneath the device to minimize parasitic inductance. The VQFN package has an exposed pad that should be soldered to the ground plane for optimal thermal performance.
The TPS62810QWRWYRQ1 can dissipate significant power at high output currents. Ensure adequate copper area on the PCB to spread heat. The datasheet recommends a minimum of 4 thermal vias under the exposed pad to conduct heat to the bottom layer. For continuous 4A operation, consider a 2-layer board with a dedicated ground plane.
Do not exceed the absolute maximum input voltage of 6V. Use a 10uF ceramic capacitor with a voltage rating of at least 10V on the input. The feedback resistor divider should use 1% tolerance resistors to maintain output voltage accuracy. Ensure the inductor saturation current rating is higher than the peak switch current to avoid core saturation.
