ADVANCE INFORMATION for pre-production products; subject to change without notice.
The architecture of the TPS6281x-Q1 allows the use of tiny ceramic output capacitors with low equivalent series resistance (ESR). These capacitors provide low output voltage ripple and are recommended. To keep its low resistance up to high frequencies and to get narrow capacitance variation with temperature, it is recommended to use X7R or X5R dielectric. Using a higher value has advantages like smaller voltage ripple and a tighter DC output accuracy in power save mode. By changing the device compensation with a resistor from COMP/FSET to GND, the device can be compensated in 3 steps based on the minimum capacitance used on the output. The maximum capacitance is 470 µF in any of the compensation settings.
