The NB672/NB673 provides a complete power supply for DDR3, DDR3L and LPDDR2 memory with the highest power density. It integrates a high frequency synchronous rectified step-down switch mode converter (VDDQ) with a 1.5A sink/source LDO (VTT) and buffered low noise reference (VTTREF). The fully integrated Buck converter of NB672/NB673 is able to deliver 6A/8A continuous output current and 8A/10A peak output current over a wide input supply range with excellent load and line regulation. The Buck converter employs the Constant-On-Time (COT) control scheme, which provides fast transient response and eases loop stabilization. The VTT LDO provides 1.5A sink/source current capability and requires only 10uF ceramic capacitance. The VTTREF tracks VDDQ/2 with an excellent 1% accuracy. Under voltage lockout is internally set as 4.5V. An open drain power good signal indicates VDDQ is within its nominal voltage range. Full protection features include OCP, OVP, and thermal shut down. These two parts require minimum number of external components and are available in QFN21 (3mmx4mm) package.
YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
NB672GL-Z is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Power Management ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official NB672GL-Z datasheet above.
Electronic component spot-market pricing for NB672GL-Z fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for NB672GL-Z depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
