== TPS54202DDCR Buck Converter (3v3) ==
* Voltage In: 4.5-28 (12-28v typical)
* Voltage Out: Variable (5v typical)
* 2 Amp continuous, ~3 Amp current limit
* Over 90% Efficency 12v to 5v buck
* Package: SOT-6, Marking: "4202"
* [https://www.lcsc.com/datasheet/lcsc_datasheet_2410010331_Texas-Instruments-TPS54202DDCR_C191884.pdf Data Sheet]
Voltage In is provided from the first 4 pins of <code>J1</code> and this component is placed at <code>U9</code> with output voltage set point resistors <code>R25/R26</code> with values 100K and 22.1K respectively. Given the equation <code>(100/22.1 + 1) * 0.596 = 3.29</code>, the voltage output provided thru inductor <code>L2</code> in this configuration is set for 3.3 volts and provides the power to the ESP32 and related components. The 3v3 rail is also accessible at [TP](8) and voltage feedback at (TP13).
== LMR51440SDRRR Buck Converter (5v) ==
* Voltage In: 4-36
* Voltage Out: 0.8-28
* Max Current: 4 Amp
* Package: 12 Pin WSON 0.8mm Height
* [https://www.lcsc.com/datasheet/lcsc_datasheet_2309221225_Texas-Instruments-LMR51450FNDRRR_C5782413.pdf Datasheet]
The component is placed at <code>U7</code> and there is a bodge jumping the voltage set point pin via <code>R19/R20</code> with a 1K resistor to correct for an in initial routing error of <code>R21/R18</code> ~18K and 100K respectively. This all results in a designed output voltage of 5 volts thru inductor <code>L1</code> and accessible at [TP](3) along with the voltage feedback at (TP10).
