... Comparator Frequency 0.7V Foldback FB Comparator 5 Functional.Description The MP1583 is a current-mode step-down regulator. It regulates input voltages from 4.75V to 23V down to an output voltage as low as 1.22V, and is able to supply load current. The MP1583 uses current-mode control to regulate the output voltage. voltage is measured at FB through a resistive voltage divider and amplified through the internal error amplifier ...
