The MPQ8634B is a fully integrated, high-frequency, synchronous, buck converter. The MPQ8634B offers a very compact solution that achieves up to 20A output current with excellent load and line regulation over a wide input supply range. The MPQ8634B operates at high efficiency over a wide output current load range. The MPQ8634B adopts an internally compensated constant-on-time (COT) control mode that provides fast transient response and eases loop stabilization. The operating frequency can be set to 600kHz, 800kHz, or 1000kHz easily with MODE configuration, allowing the MPQ8634B’s frequency to remain constant regardless of the input/output voltages. The output voltage start-up ramp is controlled by an internal 1.5ms timer. It can be increased by adding a capacitor on TRK/REF. An open-drain power good (PGOOD) signal indicates when the output is within its nominal voltage range. PGOOD is clamped at around 0.7V with an external pull-up voltage when the input supply fails to power the MPQ8634B. Fully integrated protection features include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and over-temperature protection (OTP). The MPQ8634B requires a minimal number of readily available, standard, external components and is available in a QFN-21 (3mmx4mm) package.
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.
MPQ8634BGLE-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 MPQ8634BGLE-P datasheet above.
Electronic component spot-market pricing for MPQ8634BGLE-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 MPQ8634BGLE-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.
