Buck-single-turn dual power strip

Module 1: TPS5450 is a 5.5V to 36V input 5A 500kHz buck converter. This power board supports a maximum input of 36V (pay attention to the capacitor voltage resistance selection), and is a single-power to dual-power adjustable output power module.
 
 
Module 2: MPM3620 is used as the 8-18V input of the step-down part. After step-down, it outputs plus and minus 5V, plus and minus 1A through two LDOs. The power module has strong load capacity, extremely low ripple, extremely low noise, and is fast. Transient response.
 
Module 3: Using MPM3830 as the step-down input, the input voltage is fixed at +5V, the output voltage is 3.6V, and 3.3V is output through the LDO. Mainly used for chips that require large current and low ripple, such as AD9854 (DDS). The LDO model is MAX8556, which is an ultra-low input voltage regulator that can output a current of 4A at a voltage drop of 100mV.
 
   For electric competition use, generally speaking, it does not require too much current. It is mainly used to convert single power supply to dual power supply to supply power to dual power supply op amps, etc.
(In preparation for the provincial competition, I will open source some modules during the break. I will sort out the information after the provincial competition and open source some ADC, DAC, and DDS. It should be a series.)
