The MPQ28164 is a high-efficiency, low-quiescent current, buck-boost converter that operates from an input voltage above, equal to, or below the output voltage. The MPQ28164 provides a compact solution for products powered by one-cell Lithium-ion or multi-cell alkaline batteries where the output voltage is within the battery voltage range. The MPQ28164 uses current-mode control with a fixed PWM frequency for optimal stability and transient response. The fixed 2MHz switching frequency and integrated low RDS(ON) MOSFETs minimize the solution footprint while maintaining high efficiency. To ensure the longest possible battery life, the MPQ28164 uses an optional pulse-skipping mode that reduces the switching frequency under light-load conditions. For other low-noise applications where pulse-skipping mode may cause interference, a high-logic input on the MODE/SYNC pin guarantees fixed-frequency PWM operation under all load conditions. The MPQ28164 operates with an input voltage from 1.2V to 5.5V to provide an adjustable output voltage from 1.5V to 5V. With an input from 2.5V to 5.5V, the device can supply 2A of current to the load with a 3.3V output voltage. The MPQ28164 is available in a small QFN-11 (2mmx3mm) package.
YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
MPQ28164 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 MPQ28164 datasheet above.
Electronic component spot-market pricing for MPQ28164 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 MPQ28164 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.
