Chip used#
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)

Features and specs#
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.
Board Specs - Dimensions: 23mm x 18mm x 1.6mm - Input Voltage: 3-16V - Output Voltage: 3.3V, 5V, 9V
Wiring#
Input voltage can be either from USB input (non Power Delivery) or from direct soldering VIN and GND inputs. The input voltage can not be under 3V or above 16V (risk of damaging the device).
The output voltage is adjusted using the slider to select 3,3V, 5V or 9V.
Attention
The type C port is only usable as an input and is not usable as a voltage source
Current capacities#
The maximum current it can delivers is 2A but precise regulation can not be ensured in all operating points. This operating points have been tested
