MPM3630GQV-Z Übersicht
A DC/DC power module (also called a System-in-Package or SiP regulator) integrates the synchronous buck controller, MOSFETs, inductor, and bypass capacitors inside one LGA/QFN module. This converts the part from a discrete component kit into a near drop-in PoL (Point-of-Load) building block, reducing PCB area, BOM count, and design risk compared to a discrete buck design. The module belongs to the broader power management hierarchy: DC/DC converter > synchronous buck regulator > step-down module > integrated PoL regulator.
Key features include 1.4MHz switching frequency for fast load transient response, Power Good indicator, internal soft-start, over-current protection, thermal shutdown, and under-voltage lockout. The 1.4MHz high-frequency operation allows the use of small external components while minimizing output ripple. Because the inductor is co-packaged inside the module, radiated EMI and PCB layout sensitivity are reduced compared with a discrete buck design.
The MPM3630GQV-Z uses a peak-current-mode control architecture with internal compensation. Synchronous rectification eliminates the Schottky diode of older topologies and improves efficiency at light loads. The wide 4.5V-18V input range makes it compatible with 5V, 9V, 12V, and 15V system rails commonly found in industrial, networking, and FPGA/SoC applications.
Typical applications include FPGA/SoC core and I/O rails, industrial control systems, telecom/datacom point-of-load regulation, distributed 12V bus architectures, and consumer electronics requiring compact high-efficiency 3A power. The wide input range simplifies integration into 12V industrial backplanes.
When designing with this module, place it directly over the input/output capacitor pads and minimize the loop area of the input capacitors to the module's input pins. Because the inductor is internal, no external inductor selection is required, but adequate airflow or copper heatsinking is still required at high duty-cycle, high-output-current operation.

Typische Anwendungen
MPM3630GQV-Z ist geeignet für 6 Anwendungs: FPGA / SoC Core and I/O Rails, Industrial 12V Backplane Point-of-Load, Telecom / Datacom Card Power, Portable / Battery-Powered Equipment, Automotive Infotainment and Cluster Power, LED Driver / Solid-State Lighting.
FPGA / SoC Core and I/O Rails
The MPM3630GQV-Z suits FPGA and SoC power delivery where a compact 3A point-of-load regulator is needed between a 12V intermediate bus and the 1.0V-3.3V device rails. The 1.4MHz switching frequency, fast load transient response, and integrated inductor minimize PCB area and BOM complexity around dense BGA packages such as Xilinx Zynq, Intel Cyclone, and Lattice ECP5 families. The 4.5V-18V input range lets the same module cover both 5V and 12V bus architectures, simplifying platform reuse.
Empfohlen
Industrial 12V Backplane Point-of-Load
The MPM3630GQV-Z is well matched to industrial 12V backplane distribution where multiple downstream PoL rails are required. With 4.5V-18V input tolerance and 3A continuous output, the module can convert a 12V or 15V backplane rail to 1.0V, 1.8V, 2.5V, 3.3V, or 5V system voltages without external inductor design. The QFN-style surface-mount module simplifies manufacturing and offers tighter tolerance than a discrete buck on the same PCB.
Empfohlen
Telecom / Datacom Card Power
In telecom and datacom cards the MPM3630GQV-Z can provide 3A point-of-load regulation from a 12V or 5V distribution bus to ASICs, transceivers, and DSP cores. The 1.4MHz switching frequency falls outside sensitive IF bands, the peak-current-mode control gives predictable transient response, and the integrated inductor reduces radiated EMI compared with a discrete buck - all critical for systems that must pass CE/FCC EMC requirements.
Empfohlen
Portable / Battery-Powered Equipment
For portable and battery-powered equipment the MPM3630GQV-Z offers high-efficiency synchronous rectification and low quiescent consumption, extending runtime when stepping down from a 1S-4S lithium pack (4.5V-18V). The Power Good output feeds the system microcontroller to coordinate startup sequencing, while internal soft-start prevents inrush on battery insertion. Compact footprint suits handheld instruments, e-readers, and portable test gear.
Empfohlen
Automotive Infotainment and Cluster Power
The MPM3630GQV-Z family suits automotive infotainment head units, instrument clusters, and ADAS sensor modules where a 3A buck is needed from a 12V battery rail (cold-crank tolerant down to 4.5V). Synchronous rectification and high efficiency at 12V VIN reduce thermal load in enclosed automotive enclosures. The internal protections (OCP/OTP/UVLO) and Power Good support ASIL-aware system design without external housekeeping ICs.
Empfohlen
LED Driver / Solid-State Lighting
For LED lighting strips, architectural fixtures, and solid-state lighting controls, the MPM3630GQV-Z converts a 12V or 24V (after pre-regulation) rail to a constant-current/voltage output for LED strings up to 3A. The wide 0.6V-18V adjustable output range covers most low-voltage LED forward voltages, and the 1.4MHz switching keeps the converter outside audible range, eliminating coil whine in dimming applications.

Wichtigste Unterscheidungsmerkmale
- True 3A continuous rating in a fully integrated module (vs. MPM3610GQV-Z)
- Alternate reel-packaging drop-in compatibility (vs. MPM3630GQV-P)
- Drop-in footprint reuse from 2A family (vs. MPM38222GQV-Z)
Designhinweise
Place the MPM3630GQV-Z module directly over the input and output capacitor pads and minimize the high-frequency loop area between the module input pins and the ceramic input capacitors. The exposed thermal pad must be tied to a continuous ground plane with multiple thermal vias (typically 0.3mm drill, 1mm pitch array) to keep junction temperature within the OTP threshold at full 3A load.
At VIN=18V, VOUT=3.3V, and 3A load, internal power dissipation can exceed 4W. The integrated module reduces PCB area but concentrates heat in a small footprint; design the system with copper pours directly under the EPAD, multiple thermal vias to inner planes, and adequate airflow to avoid triggering OTP. Derating above 70C ambient is recommended for industrial-temperature applications.
Estimated: with VIN=12V, VOUT=5V, 3A load, expected efficiency of ~93-95% yields about 1.4W of dissipation and a junction rise of approximately 50-70C above ambient assuming a theta_JA in the 35-45 C/W range typical for this QFN-module package - verify with a thermocouple measurement before finalizing mechanical design.
Although the MPM3630GQV-Z integrates the inductor, the SW node is internal - the only radiated EMI hot spot is the input supply loop. Place input ceramic capacitors as close as possible to the VIN/PGND pads, and consider a small ferrite bead on the input feed if the system must meet CISPR 22/32 Class B in a single 12V backplane slot.
