The MPQ8633B is a fully integrated, high-frequency, synchronous buck converter. It offers a very compact solution that can achieve up to 20A of output current (IOUT) across a wide input voltage (VIN) supply range, with excellent load and line regulation. The MPQ8633B operates at high efficiency over a wide output current load range. The MPQ8633B adopts an internally compensated constant-on-time (COT) control to provide fast transient response and eases loop stabilization. The switching frequency (fSW) can be set to 600kHz, 800kHz, or 1000kHz easily with MODE configuration, allowing fSW to remain constant regardless of the input and output voltages. The output voltage (VOUT) start-up ramp is controlled by an internal 1ms timer. It can be increased by adding a capacitor on TRK/REF. An open-drain power good (PGOOD) signal indicates whether the output is within its nominal voltage range. PGOOD is clamped at about 0.7V via an external pull-up voltage when the input supply fails to power the MPQ8633B. Full protection features include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and over-temperature protection (OTP). The MPQ8633B requires a minimal number of readily available, standard external components, and is available in a QFN-21 (3mmx4mm) package.
YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
MPQ8633BGLE-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 MPQ8633BGLE-P datasheet above.
Electronic component spot-market pricing for MPQ8633BGLE-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 MPQ8633BGLE-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.
