NCV97311MW33AR2G

Overview

The NCV97311MW33AR2G is an automotive-grade Power Management IC (PMIC) from onsemi, designed for battery-connected applications. It integrates four output regulators: two synchronous buck converters and two low-dropout linear regulators (LDOs). The device operates within an input voltage range of 4.1V to 18V and supports switching frequencies between 2MHz and 2.6MHz. Output 1 provides a fixed 3.3V at up to 3A, while Outputs 2 and 3 offer adjustable voltages from 1.2V to 3.3V with 1.5A current capability. It is housed in a 32-QFN (5x5mm) package with an exposed pad and is qualified to AEC-Q100 standards for operation across a temperature range of -40°C to 125°C.

Feature Summary

• Integrates dual synchronous buck and dual LDO regulators for multi-rail power distribution
• Automotive qualification compliant with AEC-Q100 reliability standards
• Optimized for low quiescent current in battery-connected vehicle systems

Applications

• Automotive infotainment system power distribution
• Digital cockpit controller power management
• ADAS sensor module power supply units

Procurement Notes

This component has reached End-of-Life (EOL) status as per manufacturer discontinuation notifications dated March 10, 2021. Verification of final shipment dates and last-time-buy windows is required before procurement planning. Supply availability is restricted to existing stock or authorized distributors holding legacy inventory. Engineers must validate that the specific revision matches design requirements prior to integration.

Selection Notes

Select this PMIC for designs requiring a compact solution with mixed regulation topologies in automotive environments. The fixed 3.3V/3A output suits main logic rails, while adjustable buck outputs support variable voltage domains. Ensure thermal management accounts for the 32-QFN package dissipation characteristics. Verify that the 4.1V minimum input voltage aligns with the vehicle's cold-crank and operating voltage profiles.

Part Context
