Datasheet Summary
Power Management Unit Automotive, Battery-Connected, Multi-Output
Description The NCV97310A 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 3.3 V output at a constant 2 MHz switching frequency, delivering up to 3 A. In overvoltage conditions up to 36 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...
