Product details
Overview
MPM3804GG-12-P from Monolithic Power Systems is a fully integrated, synchronous step-down DC/DC power module delivering 0.6A continuous output at a fixed 1.2V from 2.3V–5.5V input, featuring an on-board 1μH inductor, 2.4MHz switching frequency, and ultra-small 2mm × 2mm × 0.9mm QFN-10 package. It supports power sequencing via EN and PG pins and targets space-constrained low-power systems such as optical modules and IoT edge nodes.
For engineers reviewing the MPM3804GG-12-P datasheet, MPM3804GG-12-P pinout, MPM3804GG-12-P application, or MPM3804GG-12-P equivalent, key selection criteria include fixed 1.2V output accuracy (±1%), integrated inductor reliability, thermal shutdown behavior at 160°C, and compatibility with ceramic output capacitors without external compensation.
Technical Context
The MPM3804GG-12-P employs constant-on-time (COT) control with input voltage feed-forward to maintain stable 2.4MHz operation across its 2.3V–5.5V input range while achieving fast transient response and high light-load efficiency. Its internal power stage integrates 130mΩ P-FET and 100mΩ N-FET switches, enabling 1.2V regulation with ≤1% output tolerance over –40°C to +125°C junction temperature.
It features dedicated open-drain Power Good (PG) monitoring with ±7% trip thresholds (83%–90% of nominal VOUT), 0.5ms internal soft-start, output discharge capability, and hiccup-mode short-circuit protection. The device operates in discontinuous conduction mode (DCM) under light load using advanced asynchronous modulation (AAM) and zero-current detection (ZCD) for optimized quiescent current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2V ±1% (1.176V–1.224V over –40°C to +125°C), eliminating external feedback resistors and reducing BOM count. |
| Max Output Current | 0.6A continuous, sufficient for powering low-voltage I/O rails, sensor interfaces, and microcontroller cores in portable devices. |
| Input Voltage Range | 2.3V to 5.5V - supports single-cell Li-ion, USB-powered, and multi-rail industrial supplies without pre-regulation. |
| Switching Frequency | 2.4MHz typical (1.8–3.0MHz over temp), enabling compact external capacitor selection and minimizing EMI in noise-sensitive applications. |
| Quiescent Current | 340–400μA - enables >10-year battery life in always-on IoT sensors when paired with low-IQ system architecture. |
| Thermal Shutdown | 160°C with 30°C hysteresis - provides robust overtemperature protection while allowing safe derating up to 125°C ambient. |
| Power Good Accuracy | PG asserts when VOUT reaches 90% of 1.2V and deasserts at 83%, ensuring reliable system power sequencing and brownout detection. |
Pinout & Package
MPM3804GG-12-P is housed in an ultra-compact, thermally enhanced QFN-10 package (2mm × 2mm × 0.9mm) with exposed thermal pad. The package supports reflow soldering per JEDEC J-STD-020, MSL Level 3, and features 10 terminals arranged in a 2×5 grid with Pin 1 marked by a dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VIN | Unregulated input supply | Accepts 2.3V–5.5V; requires local 10μF ceramic decoupling to suppress high-frequency switching noise. |
| 2,3,4 SW | Internal switch node | Drain connection of integrated high-side P-FET; not accessible externally-no test point or routing required. |
| 5 EN | Enable control input | Active-high logic (≥1.2V); internal 1MΩ pull-down allows default disable; enables precise power sequencing. |
| 6,7,8 OUT | Regulated output rail | Delivers 1.2V/0.6A; connects directly to load and output capacitor; multiple pins reduce IR drop and improve thermal spreading. |
| 9 PG | Open-drain power good indicator | Requires external 100kΩ–500kΩ pull-up; sinks current when VOUT falls below 83% of 1.2V, signaling fault condition. |
| 10 GND | Power ground reference | Primary return path for input/output currents; must be connected to thermal pad for optimal thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 1μH power inductor | Eliminates external magnetics, reduces PCB area by >40% vs discrete buck solutions, and ensures consistent DCR (0.4Ω) and saturation current. |
| 2.4MHz COT control | Enables use of small 22μF ceramic output capacitors while maintaining <20mV ripple and sub-10μs load transient recovery. |
| Output discharge function | Activates internal MOSFET upon EN deassertion to safely discharge VOUT within milliseconds-critical for hot-swap and safety-critical systems. |
| Hiccup-mode short-circuit protection | Disables switching, discharges soft-start capacitor, and retries startup every ~10ms until fault clears-prevents thermal runaway during sustained shorts. |
| Stable with low-ESR ceramics only | No external compensation required; supports X5R/X7R MLCCs down to 10μF, simplifying layout and improving long-term reliability vs tantalum/electrolytic. |
Applications
| Optical Transceivers | Industrial Sensor Nodes |

FAQ
What is the recommended input capacitor for MPM3804GG-12-P?
A 10μF X5R or X7R ceramic capacitor placed adjacent to VIN and GND is recommended. It must withstand RMS current ≥0.3A and provide sufficient charge to limit input ripple to <50mV. Adding a 0.1μF ceramic in parallel improves high-frequency decoupling.
Does MPM3804GG-12-P require external compensation components?
No. The constant-on-time control architecture and internal loop compensation eliminate the need for external RC networks. Stability is guaranteed with standard 10–22μF ceramic output capacitors and their inherent ESR characteristics.
How does the Power Good (PG) pin behave during startup and fault conditions?
PG remains low until VOUT reaches 90% of 1.2V (1.08V), then pulls high via external pull-up. If VOUT drops below 83% (0.996V) due to overload or input dip, PG actively sinks current to ground, signaling a fault to the host controller within 10μs.
Can MPM3804GG-12-P operate in dropout mode?
Yes. It supports 100% duty cycle operation, allowing VOUT regulation even when VIN approaches 1.2V (minimum VIN = 1.2V + diode drop ≈ 1.3V). However, efficiency drops significantly below VIN = 1.8V due to increased conduction losses.
What is the thermal pad soldering requirement for QFN-10 package?
The exposed thermal pad must be soldered to a minimum 4mm² copper pour connected to GND with ≥4 thermal vias (0.3mm diameter, filled or capped). This achieves the specified θJA = 80°C/W and prevents junction temperature exceedance above 125°C ambient.
Is output discharge active during EN pin assertion or deassertion?
Output discharge activates only when EN is pulled low or left floating (due to internal 1MΩ pull-down). It discharges VOUT through a 1kΩ internal resistor, reducing 1.2V to <100mV in <5ms with a 22μF output capacitor.
What is the maximum allowable output capacitance?
No hard upper limit exists, but exceeding 100μF may extend soft-start time beyond 0.5ms and increase inrush current. For most applications, 10–47μF ceramic capacitors provide optimal trade-off between ripple suppression and startup behavior.
