Overview
The NCV97311MW50AR2G is an automotive-grade Power Management IC featuring four integrated outputs: two synchronous buck regulators and two low-dropout linear regulators. It operates within a supply voltage range of 4.1V to 18V and supports switching frequencies between 2MHz and 2.6MHz. The device is housed in a 32-QFNW (5x5) package with wettable flanks, designed for high thermal performance and reliable surface mount assembly in demanding environments.
Feature Summary
- Integrates dual synchronous buck converters and dual LDOs for comprehensive power distribution
- Features AEC-Q100 qualification for automotive reliability standards
- Supports surface mount installation with wettable flank technology for enhanced inspection
Applications
- Automotive battery-connected systems requiring multi-rail power management
- Electronic control units needing synchronized buck regulation
- Low-noise applications utilizing integrated LDO outputs
Procurement Notes
Verify the specific suffix 'MW50AR2G' against official onsemi documentation to confirm the exact output configuration and packaging variant. Ensure compatibility with the required input voltage range and thermal dissipation requirements for the target application environment before finalizing procurement.
Selection Notes
Select this component when a single solution is required for both switching and linear regulation in automotive designs. The integrated topology reduces external component count compared to discrete solutions. Verify that the 32-QFNW package footprint aligns with the PCB layout constraints and that the 2MHz to 2.6MHz frequency range meets EMI requirements.
Part Context
This part belongs to the NCV97311 series of specialized PMICs designed for automotive applications. It provides a consolidated power management solution, combining high-efficiency switching regulators with precise linear regulators to support complex electronic architectures in vehicles.
Replacement Considerations
Check for other variants within the NCV97311 family that may offer different fixed output voltages or current ratings if the MW50AR2G specifications do not fully match the design requirements.
