JAJSJT8C May 2020 – June 2021 TPS543620
The TPS543620 is designed to operate from an input voltage supply range between 4 V and 18 V. This supply voltage must be well regulated. Proper bypassing of the input supply is critical for proper electrical performance, as is the PCB layout and the grounding scheme. A minimum of 4 μF (after derating) ceramic capacitance, type X5R or better, must be placed near the device. TI recommends splitting the ceramic input capacitance equally between the VIN and PGND pins on each side of the device resulting in at least 2 µF of ceramic capacitance on each side of the device.
