Product details
Overview
MPM3506AGQV-P from Monolithic Power Systems is a fully integrated synchronous step-down DC/DC power module with built-in MOSFETs, inductor, and input/output capacitors. It delivers 0.6A continuous output current across a 4.5V–36V input range, operates at a fixed 1.15MHz switching frequency, and provides adjustable output voltage down to 0.81V. It is used in space-constrained industrial and automotive subsystems requiring compact, reliable point-of-load regulation.
For engineers reviewing the MPM3506AGQV-P datasheet, MPM3506AGQV-P pinout, MPM3506AGQV-P application, or MPM3506AGQV-P equivalent, key selection criteria include its QFN-19 (3mm×5mm) integrated module footprint, valley-current–based over-current protection with hiccup mode, power-good indicator timing (30–160μs), thermal shutdown threshold (165°C), and 800kHz–2MHz external clock synchronization capability.
Technical Context
The MPM3506AGQV-P employs peak-current–mode control with internal compensation, enabling stable regulation without external loop components. Its advanced asynchronous modulation (AAM) enables pulse-frequency modulation (PFM) during light loads, reducing quiescent current to 0.58mA while maintaining output accuracy.
It integrates a 5V internal LDO (VCC) powered from VIN, eliminating need for an external VCC capacitor, and uses an internal bootstrap capacitor with dedicated charging circuitry-no external BST diode required unless duty cycle exceeds 65%. The EN/SYNC pin supports both enable/disable control and external frequency synchronization between 800kHz and 2MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 36V - supports wide industrial and automotive battery rails including 12V, 24V, and 36V systems. |
| Output Current | 0.6A continuous - sufficient for powering microcontrollers, sensors, and interface ICs in compact embedded designs. |
| Switching Frequency | Fixed 1.15MHz (±15%) - enables small external passive components and fast transient response; syncable from 800kHz to 2MHz. |
| Feedback Reference | 0.81V ±1.5% - sets precise output voltage via external resistor divider; supports outputs from 0.81V to near VIN. |
| Thermal Shutdown | 165°C activation with 20°C hysteresis - protects against sustained overload or poor PCB thermal design without latch-off. |
| Power Good Delay | Rising: 30–160μs, Falling: 25–95μs - provides deterministic sequencing margin for downstream logic and processors. |
| Quiescent Current | 0.58mA typical at VFB = 1V - enables low-power standby operation in always-on subsystems. |
Pinout & Package
MPM3506AGQV-P is housed in a thermally enhanced QFN-19 package (3mm × 5mm × 1.6mm) with exposed PGND paddle for efficient heat dissipation. Pin layout supports high-current routing and minimal board area usage.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback input | Connects to resistor divider tap; sets output voltage with 0.81V reference; sensitive node requiring short, direct routing. |
| 2 VCC | Internal 5V LDO output | Supplies internal circuitry; no external capacitor needed due to integrated decoupling. |
| 3 AGND | Analog ground reference | Reference for error amplifier and control logic; internally tied to PGND but requires separate low-noise routing. |
| 4–6 SW | Switch node | High-frequency drain connection of internal HS-FET; requires large copper pour for thermal and EMI performance. |
| 7–9 OUT | Regulated output | Delivers filtered DC output; connects directly to load and output capacitor; high-current path. |
| 10,14,18,19 NC | No connection | Must remain unconnected and floating; not bonded or functional. |
| 11 BST | Bootstrap supply | Internally charged; no external diode or capacitor required under standard operating conditions. |
| 12–13, PGND | Power ground | Main return path for high-side/low-side FETs and inductor; must be connected to large thermal pad with multiple vias. |
| 15 VIN | Main input supply | Accepts 4.5V–36V; requires low-ESR ceramic capacitor placed adjacent to minimize input ripple and EMI. |
| 16 EN/SYNC | Enable & frequency sync | Digital input: high = enable, low/floating = disable; accepts external clock (800kHz–2MHz) for EMI reduction. |
| 17 PG | Power good open-drain | Signals valid output (84–91% of VFB); requires external pull-up for system sequencing or fault monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Complete power solution | Integrates MOSFETs, inductor, and two capacitors - reduces external BOM to only 4 components (resistor divider + input/output caps). |
| Light-load efficiency | AAM (asynchronous modulation) enables PFM operation below ~100mA, cutting quiescent current to 0.58mA without sacrificing regulation. |
| Robust fault protection | Valley-current detection + hiccup-mode OCP prevents thermal runaway during short-circuit; TSD at 165°C with auto-recovery. |
| Output voltage flexibility | Adjustable from 0.81V using external resistor divider; supports common rails (1.2V, 1.8V, 2.5V, 3.3V, 5V) with <±1.5% reference accuracy. |
| EMI-aware synchronization | EN/SYNC pin accepts external clock (800kHz–2MHz) to align switching edges - critical for noise-sensitive applications like imaging or RF subsystems. |

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 |
|---|---|---|---|
| RT6220BGE | Higher 1.2A output, 2.5MHz fixed frequency, no integrated inductor - requires external magnetics and more layout effort. | Better suited for higher-current, lower-profile applications where board space permits external inductor placement. | Select RT6220BGE only if >0.6A output or >2MHz switching is mandatory; MPM3506AGQV-P offers faster time-to-market with zero magnetics design. |
| TPS82084SILR | 0.6A output, 2.2MHz, smaller 2.3mm×2.7mm package, but narrower 2.5V–6V input range - unsuitable for 12V/24V industrial rails. | Targeted at portable battery-powered devices (Li-ion, USB-PD), not wide-input industrial or automotive use. | Choose TPS82084SILR only for single-cell or USB-powered systems; MPM3506AGQV-P is the only qualified option for 4.5V–36V input with integrated inductor. |
Compared with RT6220BGE and TPS82084SILR, the MPM3506AGQV-P uniquely balances wide-input operation (4.5V–36V), full integration (inductor + caps), and industrial temperature support in a production-ready QFN-19 footprint - making it optimal for cost-sensitive, space-constrained 0.6A PoL applications outside portable battery domains.

FAQ
What is the minimum output voltage supported by the MPM3506AGQV-P?
The MPM3506AGQV-P supports output voltages starting at 0.81V, set by its internal feedback reference voltage. Using an external resistor divider, outputs as low as 0.81V can be achieved with ±1.5% reference accuracy across temperature, enabling direct supply to modern low-voltage MCUs and FPGAs.
Does the MPM3506AGQV-P require an external bootstrap diode?
No external bootstrap diode is required under standard operating conditions. The device integrates a bootstrap capacitor and dedicated charging circuit. An external diode (e.g., 1N4148) is only recommended when VOUT ≥ 5V and duty cycle exceeds 65%, to improve efficiency in high-VIN/low-VOUT scenarios.
How does the power-good (PG) signal behave during startup and fault conditions?
The PG pin is an open-drain output that asserts high when VOUT reaches 84–91% of the target voltage and remains asserted until VOUT drops below 79–86% of target. Its rising delay is 30–160μs and falling delay is 25–95μs - providing deterministic timing for system reset and sequencing logic.
Can the MPM3506AGQV-P operate with input voltage below 4.5V?
No - the absolute minimum operating VIN is 4.5V per datasheet specifications. Operation below this threshold triggers UVLO, disabling regulation. For sub-4.5V inputs, alternative regulators such as the MPS MP2451 (2.5V–6V input) must be considered.
What thermal derating applies above +85°C ambient?
The device is rated for junction temperatures up to +125°C. With θJA = 46°C/W on a 4-layer PCB, maximum continuous power dissipation decreases linearly above +25°C ambient. At +85°C ambient, usable power drops to ~1.2W before thermal shutdown activates at 165°C junction temperature.
Is the MPM3506AGQV-P pin-compatible with earlier revisions like MPM3506AGQV?
Yes - the MPM3506AGQV-P is a drop-in replacement for MPM3506AGQV, sharing identical pinout, electrical characteristics, and thermal profile. The "-P" suffix denotes tape-and-reel packaging with enhanced moisture sensitivity level (MSL) handling, not functional revision.
