Sysrox SRX-POW01-NANO is a high-performance DC-DC buck-boost converter capable of delivering a 3.3V or 5V output from an input voltage of 3-16V, with low ripple regardless of the load.
The regulator is based on the TI TPS63070 chip, offering:
A maximum output current of 2A in both buck and boost modes
Efficiency up to 95%
DC voltage regulation accuracy of ± 1% (± 3% at low load)
50 µA quiescent current
Low output ripple30 mV in PWM mode
50 mV in PFM mode (for zero or low load)

Module Features The provided board can be powered directly by a voltage source between 3V and 16V. A VSEL pin allows selecting the fixed output voltage: 3.3V by default or 5V when VSEL is set high. VSEL can be toggled during operation.
This module is ideal for prototyping needs or for direct integration into robotic applications. It includes protections against over-temperature and excessive output voltage, but does not include protection against negative voltages.
