NCV70522DQ004R2G

NCV70522DQ004R2G is an automotive-grade DC-DC buck converter in a DQ004R2G (QFN) package. It is designed to generate a stable lower-voltage rail from a wide automotive input while meeting harsh vehicle conditions.
Key features (typical):
- Wide automotive input range with fixed/adjustable output options via a feedback network
- High-efficiency switching regulator
- Protections: overcurrent/short-circuit, overvoltage/UVLO, undervoltage, thermal shutdown
- Enable/shutdown control and soft-start
- RoHS-compliant, suitable for harsh vehicle environments
Applications:
- Infotainment and body electronics
- Power rails for ECUs, sensors, and microcontrollers
How to use:
- Verify pinout and implement the feedback network per datasheet
- Follow recommended input/output capacitor choices and layout guidelines
- Ensure adequate heat dissipation and EMI mitigation
Note: I can provide exact electrical specs (input range, output voltage, current limit) or a datasheet link if you’d like.

Pin count depends on the exact package variant. Please confirm the package code (e.g., QFN/pin count for DQ004R2G). I can fetch the official datasheet and give the exact pin count and each pin’s function.
