The Sysrox SRX-POW00_DEV is a high-performance DC-DC buck-boost converter, capable of delivering an output voltage of 3.3V, 5V, or 9V from an input voltage ranging from 3V to 16V, with low ripple regardless of the load.
The regulator is based on the TI TPS63070 chip, offering:
Maximum output current: 2A in boost or buck mode
Efficiency: Up to 95%
DC voltage accuracy: ± 1% (± 3% with light load)
Quiescent current: 50 µA
Low voltage ripple:30 mV in PWM mode
50 mV in PFM mode (no load or light load)

The board can be powered by USB (not compatible with USB-C PD) or directly by a voltage source ranging from 3V to 16V. A switch allows the user to select a fixed output voltage: 3.3V for the leftmost position, 5V for the middle position, and 9V for the rightmost position. The switch can be toggled during operation.
This module is ideal for prototyping needs and includes protections against negative voltages, over-temperature, and excessive output voltages.
Dimensions: 23mm x 18mm x 1.6mm
Input Voltage: 3-16V
Output Voltage: 3.3V, 5V, 9V
