First part of Dave Jones's series designing a lab power supply with op-amp voltage and current regulation; recommended as an introduction to bench supply design.
Dave Jones walks through designing a switch-mode supply around the MC34063, often pointed to as a hands-on introduction to buck and boost converters.
Dave Jones's EEVblog series designing a precision bench power supply from scratch, valued for showing a working engineer's reasoning as much as the circuit itself.
Dave Jones explains why designers use several electrolytic capacitors in parallel instead of one large one, mainly to lower ESR and spread the load.
Adds a current limit to a cheap buck/boost module with a sense resistor and comparator; people borrow the circuit for CC/CV chargers and motor supplies.
Part four of Dave Jones's lab power supply series covers PWM control filtered to an analogue voltage; also cited for spotting probing artefacts on a scope.
Explains how a DC-DC boost converter steps voltage up with an inductor, switch and diode; the usual link for people puzzling over cheap USB step-up modules.
