The NB671LB is the low quiescent current version of NB671. It is a fully integrated high frequency synchronous rectified step-down switch mode converter, which offers very compact solutions to achieve 6A continuous output current and 9A peak current over a wide input supply range with excellent load and line regulation. The NB671LB operates at high efficiency over a wide output current load range. Constant-On-Time (COT) control mode provides fast transient response and eases loop stabilization.Under voltage lockout is internally set as 4.2 V, An open drain power good signal indicates the output is within its nominal voltage range.Full protection features include OCP, OVP, and thermal shut down. The converter requires minimum number of external components and is available in QFN16 (3mmx3mm) package.The NB671LB is pin-to-pin compatible with NB671 with a NC pin changed to LP#, which is used to receive the power state command from the system.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
NB671LBGQ-P 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 NB671LBGQ-P datasheet above.
Electronic component spot-market pricing for NB671LBGQ-P 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 NB671LBGQ-P 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.
