10 Power Supply Recommendations

The TPS5516x-Q1 family of devices is a power-management device. The power supply for the device is any DC-voltage source within the specified input range. The supply should also be capable of supplying sufficient current based on the maximum inductor current in boost-mode operation. When connecting to the power supply and load, try to use short and solid wires. Twisting the pair of wires for the input and output helps minimize the line impedance and avoid adversary interference with the circuit operation.
