NCV97310MW33R2G Description
The NCV97310MW33R2G 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.
