NCV97310A Datasheet Power Management

Manufacturer: onsemi

Overview: Power Management Unit Automotive, Battery-Connected, Multi-Output.

General 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.
