Low-quiescent DC/DC buck converter in TSMC 22ULL supporting an 1.62 V to 3.63 V input voltage range with low quiescent current and high efficiency at light load. No LL PMOS layer required (no extra ...

If you want a refresher on how a buck converter — that is, a DC to DC converter that reduces a higher input voltage to the desired voltage — works we had a good brief video about that recently.
