12 V to 5 V / 1 A Buck Molecule (TPS54202)
Public Unreviewedby John Lauer
An independently designed 12 V to 5 V, 1 A synchronous buck molecule (TI TPS54202), with calculations, ngspice and PSpice simulation, KiCad 10 schematic and board, and the board laid out and analysed with adom-aiflow.

SPICE -Before any copper, the circuit is simulated in ngspice, running right in the container: the soft start from 12 V, a load step from 0.5 A to 1 A, and the inductor current through both.

Hydrogen keeps the plots in a web view next to the design, so the numbers that justify each part value sit on the same screen as the circuit.
