Electrical Specifications

Unless otherwise noted, V = AVDD = DVDD = PVINx = EN = M/S = 3V or 5.5V; GND = AGND = DGND = PGNDx = 0V; FB = 0.65V;

PORSEL = V for 4.5V ≤ V ≤ 5.5V and GND for V < 4.5V; SYNC = LXx = open circuit; PGOOD is pulled up to V with a 1k

resistor; REF is bypassed to GND with a 220nF capacitor; SS is bypassed to GND with a 100nF capacitor; I

= 0A;
