The MPQ8633A-H is a fully integrated, high-frequency, synchronous step-down converter. It offers a very compact solution that can achieve up to 12A of output current (IOUT) across a wide input voltage (VIN) range, with excellent load and line regulation. The MPQ8633A-H operates at high efficiency across a wide IOUT load range. Internally compensated constant-on-time (COT) control provides fast transient response and eases loop stabilization. The selectable switching frequency (fSW) can be set to 600kHz, 800kHz, or 1000kHz by configuring the MODE pin. This maintains a constant fSW, regardless of VIN and the output voltage (VOUT). During start-up, the internal soft-start time (tSS) (1ms) ramps up VOUT in a controlled manner. tSS can be increased by adding a capacitor on the TRK/REF pin. An open-drain power good (PG) signal indicates whether VOUT is within its nominal voltage range. If the input fails to supply power to the MPQ8633A-H, then the PG voltage (VPG) is clamped at about 0.7V via an external pull-up voltage. Full protection features include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and over-temperature protection (OTP). The MPQ8633A-H 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.
MPQ8633A-HGLE 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 MPQ8633A-HGLE datasheet above.
Electronic component spot-market pricing for MPQ8633A-HGLE 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 MPQ8633A-HGLE 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.
