5 Buck Regulators with Low Iq
https://www.electronics-lab.com/5-buck-regulators-low-iq/
Low quiescent current, also called supply current, might be an important spec for your power-supply design.. by Paul Rako @ electronicdesign.com Quiescent current is the current that a chip needs to operate even if it’s not delivering power. It’s the bare minimum supply current the chip will use. For buck-regulator chips, improved processes have reduced […]
