Product details
Overview
MPM3606GQV-Z from Monolithic Power Systems is a synchronous step-down DC/DC power module integrating MOSFETs, inductor, VCC and bootstrap capacitors in a single QFN-20 package. It delivers 0.6A continuous output current across 4.5V–21V input, regulates output from 0.8V to 5.5V, operates at 2MHz fixed frequency, and supports selectable AAM (power-save) or forced PWM mode via external resistor on AAM pin - used in space-constrained industrial and medical power rails.
For engineers reviewing the MPM3606GQV-Z datasheet, MPM3606GQV-Z pinout, MPM3606GQV-Z application, or MPM3606GQV-Z equivalent, key selection criteria include integrated inductor footprint reduction, 200μA quiescent current in light-load AAM mode, thermal shutdown at 150°C with 20°C hysteresis, 100mΩ/50mΩ high-side/low-side RDS(ON), and compatibility with ceramic input/output capacitors for low-ripple 3.3V/5V point-of-load conversion.
Technical Context
The MPM3606GQV-Z implements peak-current-mode control with internal 0.8V reference and optimized compensation network, eliminating need for external loop components. Its AAM pin accepts a resistor-to-ground to set transition voltage (0–1V) between pulse-frequency modulation (PFM) and continuous conduction mode (CCM), balancing light-load efficiency against output ripple and transient response.
It features cycle-by-cycle over-current protection with hiccup recovery, under-voltage lockout (UVLO) with 3.9V rising threshold and 650mV hysteresis, and internal 5V LDO regulator powering control circuitry - all operating across –40°C to +125°C junction temperature range. The integrated bootstrap capacitor eliminates external BST capacitor requirements.

Pinout & Package
MPM3606GQV-Z uses a thermally enhanced QFN-20 (3mm × 5mm × 1.6mm) package with exposed thermal pad (pins 12, 13, 14 PGND and pin 4, 5, 6 SW share large copper areas). The package integrates inductor and capacitors, reducing total solution size to 6.7mm × 6.3mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback Input | Connects to resistor divider tap; internal 0.798V reference enables precise output voltage setting and fold-back during short-circuit. |
| 2 VCC | Internal 5V LDO Output | Supplies internal logic; integrated decoupling capacitor eliminates need for external VCC cap. |
| 3 AGND | Analog Ground | Reference for error amplifier and control logic; internally tied to PGND - no external connection required. |
| 4,5,6 SW | Switch Node | High-current path connecting internal HS/LS MOSFETs to integrated inductor; requires large copper pour for thermal dissipation. |
| 7,8,9 OUT | Power Output | Delivers regulated DC output; connects directly to load and output capacitor (C2). |
| 11 BST | Bootstrap Supply | Internally generated - no external BST capacitor needed; simplifies layout and improves reliability. |
| 12,13,14 PGND | Power Ground | Return path for high-current switching; must be connected to thermal pad and low-impedance ground plane. |
| 16 IN | Input Supply | Accepts 4.5V–21V; requires low-ESR ceramic capacitor placed adjacent to minimize input ripple and EMI. |
| 17 EN | Enable Control | Digital ON/OFF control; floating or pulled low disables converter; internal 1MΩ pull-down enables default-off operation. |
| 18 AAM | Advanced Asynchronous Modulation | Sets PFM/CCM transition point via resistor-to-ground; 6.2μA internal current source enables programmable light-load efficiency. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Inductor + Capacitors | Reduces BOM count to only 5 external components (2 resistors, 2 capacitors, 1 AAM resistor) and eliminates inductor selection, placement, and EMI tuning effort. |
| 2MHz Fixed-Frequency Operation | Enables use of 1–2.2μF ceramic output capacitors and sub-10mm² total footprint - critical for wearable and portable medical devices. |
| AAM Mode Programmability | Resistor-based AAM voltage setting (0–1V) allows trade-off tuning between light-load efficiency (>85% at 1mA), output ripple (<15mVpp), and load transient recovery time (<50μs). |
| Hiccup Over-Current Protection | Enters periodic restart mode during sustained overload or short-circuit, limiting average fault current to <100mA and preventing thermal runaway. |
| Thermally Optimized QFN-20 | θJA = 46°C/W on 4-layer PCB; exposed thermal pad and SW/PGND pin grouping enable >0.6A continuous operation at +85°C ambient without heatsink. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPM3610GQV-Z | Higher 1A output current, same 2MHz frequency and QFN-20 package; 120mΩ/60mΩ RDS(ON); wider 4.5V–28V input range. | Supports higher-power loads (e.g., multi-core MCUs); requires larger input/output caps for stability at 1A. | Select when >0.6A continuous current or >21V input is required; pinout and FB/AAM logic are identical. |
| TFS7700H-12 | 12V fixed-output, non-adjustable module; 0.8A rating; 500kHz switching; larger 7mm × 7mm package; no AAM pin. | Designed for cost-sensitive fixed-rail applications; lacks programmable light-load mode and adjustable VOUT. | Choose only for simple 12V-to-12V regulation where footprint and efficiency flexibility are secondary to unit cost. |
Compared with MPM3606GQV-Z, MPM3610GQV-Z offers headroom for future power scaling while retaining layout compatibility, whereas TFS7700H-12 sacrifices adjustability and light-load optimization for lower bill-of-materials cost in fixed-voltage deployments.

FAQ
What is the minimum output voltage achievable with MPM3606GQV-Z?
The MPM3606GQV-Z supports output voltages down to 0.8V, set by the internal 0.798V feedback reference and external resistor divider. Operation below 0.8V is not specified or guaranteed; attempting it may cause regulation failure or instability due to comparator headroom limitations.
Can the AAM pin be left unconnected?
Yes - leaving the AAM pin floating applies ~6.2μA internal current into an open circuit, resulting in >2.5V at the pin, which forces continuous CCM operation. This is valid but forfeits light-load efficiency benefits; for optimal PFM behavior, connect a resistor to GND per Table 1.
Is an external bootstrap capacitor required?
No. The MPM3606GQV-Z integrates the bootstrap capacitor internally, and pin 11 (BST) is reserved - no external connection or component is needed. This eliminates a common source of layout error and improves reliability in high-vibration environments.
How does thermal shutdown interact with hiccup mode?
Thermal shutdown (150°C) and hiccup over-current protection operate independently: hiccup responds to current faults within microseconds, while thermal shutdown triggers only after die temperature exceeds its threshold. Both cause full shutdown, but thermal recovery occurs at ~130°C, whereas hiccup restarts every ~500ms until fault clears.
What is the maximum recommended output capacitance?
No absolute maximum is specified, but stability is ensured with 10–47μF ceramic output capacitors (X5R/X7R). Larger values (>100μF) may degrade phase margin; if needed for ripple reduction, add series resistance or use mixed-ceramic/tantalum configurations validated per Figure 13 in the datasheet.
Does MPM3606GQV-Z support output discharge?
No. The device lacks an active output discharge FET or dedicated DIS pin. During shutdown, the output discharges only through the load and feedback resistors; for rapid discharge requirements, an external NMOS switch controlled by EN is recommended.
What PCB layout practices prevent oscillation?
Place the input capacitor (10μF ceramic) within 2mm of pins 16 (IN) and 12/13/14 (PGND), use solid inner-layer ground planes tied to the exposed thermal pad with ≥6 vias, route FB traces away from SW node, and avoid splits or slots under the IC - these practices maintain loop stability and minimize EMI-induced regulation errors.
