TPS54120: Power Supply Schematic Review for Reduced Noise

Part Number: TPS54120
Other Parts Discussed in Thread: THS4541, TPS62913, TPS62912


Below are my three different needs of powersupply for low noise applications(Analog Front end using THS4541 and ADC3669) for which i have chosen TPS54120, I request TI to kindly drop comments if any major flaws are observed in the design.

1. 12V Input, 5V output for Imax = 1A

2. 12V Input, 1.8V output for Imax = 1A

3. 12V Input, 3.3V output for Imax = 1A
