Overview
Power Management Unit Automotive, Battery-Connected, Multi-Output NCV97311 Description The NCV97311 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 switchers.
Each downstream output is adjustable from 1.
2 V to 3.
3 V, with a 1.
5 A average current limit and a constant 2 MHz switching frequency.
Each switcher has an independent enable and reset pin, giving extra power management flexibility.
For low−Iq operating mode, th...
