MP2499AGQB-Z

MP2499AGQB-Z is a DC-DC buck regulator IC from Monolithic Power Systems (MPS), part of the MP2499 family. It’s designed to convert a higher input voltage to a lower, regulated output with high efficiency, for powering core rails in processors, memory, and other digital circuits. Typical features (as with MP2499 devices) include:
- Programmable output via feedback network and enable/shutdown control
- High-efficiency operation with fast transient response
- Switching-frequency control and/or synchronization options
- Protection features such as overcurrent, thermal/overtemperature, undervoltage lockout
- Compact packaging (suffix -Z denotes a specific package/reel code)
The exact electrical specs (VIN range, VOUT, IOUT, efficiency, switching frequency, and protection thresholds) depend on the specific variant and packaging. For precise details, consult the official MP2499 datasheet and the supplier’s documentation for the AGQB-Z variant.

I don’t have the exact datasheet on hand, but the MP2499AGQB-Z (Monolithic Power Systems) generally offers features typical for the MP2499 family. Key features commonly include:
- Wide input voltage range (roughly 4.5 V to 60 V)
- High-efficiency switching regulator suitable for automotive/industrial applications
- Integrated power MOSFETs in a compact package (synchronous topology; some variants allow external MOSFETs)
- Programmable output current/voltage via external resistors
- Dimming support (PWM and/or analog) for LED/backlight applications
- Soft-start and current-mode control for stable startup and response
- High efficiency across load ranges
- Protections: UVLO, overvoltage protection, overcurrent/short-circuit protection (often with hiccup), thermal shutdown
- Fault latch and safe-operating features
- Fixed or adjustable switching frequency (depending on variant)
- Package: small QFN/leadless package with exposed pad (AGQB-Z denotes package/grade)
For precise specs (Vin range, Vout/ILED ranges, current-sense details, and exact package), please share the datasheet or confirm the exact variant. I can summarize accurately from it.

MP2499AGQB-Z is supplied in a 16-pin QFN (3.0 mm × 3.0 mm) GQB package. The “-Z” suffix indicates tape-and-reel packaging for automated assembly.

Manufacturer: Monolithic Power Systems (MPS).
Company type: A fabless semiconductor company that designs and markets high-performance analog and mixed-signal power-management ICs (e.g., DC-DC controllers, regulators, PMICs) and outsources fabrication to foundries.

MP2499AGQB-Z is a high‑efficiency multi‑phase buck regulator controller for DC‑DC conversion. Typical applications:
- CPU/GPU core voltage rails (VRMs)
- Desktop/server multi‑phase power modules
- Notebook power modules
- FPGA/ASIC power supplies
- Telecom/industrial DC‑DC rails
(Appropriate for high‑current, tightly regulated power conversion across these areas.)
