is a 3−output regulator consisting of a low−Iq battery−connected 3 A, 2 MHz non−synchronous switcher and two low−voltage 1.5 A, 2 MHz synchronous switchers; all using integrated power transistors. The high−voltage switcher is capable of converting a 4.1 V to 18 V battery input to a 5 V or 3.3 V output at a constant 2 MHz switching frequency, delivering up to 3 A. In overvoltage conditions up to 37 V, the switching frequency folds back to 1 MHz; in load dump conditions up to 45 V the regulator shuts down. The output of the battery−connected buck regulator serves as the low voltage input for the 2 downstream synchronous swit
