Product details
Overview
MPM3807CGLE-18-AEC1-P from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, fully integrated synchronous step-down power module delivering up to 2A continuous output at fixed 1.8V, with 2.4MHz switching frequency, 1% FB accuracy, and operation from 2.5V–5.5V input - designed for automotive ADAS sensors and camera modules requiring compact, thermally robust DC/DC conversion.
For engineers reviewing the MPM3807CGLE-18-AEC1-P datasheet, MPM3807CGLE-18-AEC1-P pinout, MPM3807CGLE-18-AEC1-P application, or MPM3807CGLE-18-AEC1-P equivalent, this page delivers verified package mapping (QFN-15, 3mm×4mm×1.6mm), validated thermal performance (−40°C to +150°C TJ), confirmed protection features (SCP hiccup, OVP, PG), and real-world design constraints including wettable flank solderability and FCCM EMI optimization.
Technical Context
The MPM3807CGLE-18-AEC1-P implements constant-on-time (COT) control with VIN feed-forward, enabling stable 2.4MHz operation across 2.5V–5.5V input and load transients while maintaining fast response without external compensation. Its integrated 70mΩ high-side and 40mΩ low-side MOSFETs, plus 470nH inductor, form a complete power stage within a single QFN-15 wettable flank package.
It operates in forced continuous conduction mode (FCCM) across full load range, eliminating mode transitions and minimizing output ripple. The fixed 1.8V output version internally connects FB to reference, eliminating external resistors; power good (PG) asserts when VFB exceeds 90% of 0.6V, and output discharge via OUT_S provides controlled shutdown behavior.
Key Specifications

| Max Output Current | 2A continuous - supports high-current automotive imaging sensors and SoC cores without external heatsinking under typical PCB conditions. |
| Input Voltage Range | 2.5V to 5.5V - compatible with 3.3V and 5V automotive rails, including post-regulated battery domains. |
| Switching Frequency | 2.4MHz (±10%) - enables use of small external capacitors and minimizes audible noise; FCCM ensures consistent frequency under all loads. |
| Thermal Rating | Junction temperature −40°C to +150°C - certified AEC-Q100 Grade 1, suitable for under-hood and ADAS sensor placement. |
| Feedback Accuracy | ±1% over temperature - ensures stable 1.8V supply for sensitive image signal processors and SerDes interfaces. |
| Protection Features | Short-circuit hiccup, output over-voltage (115% VREF), thermal shutdown (170°C), and cycle-by-cycle current limiting - enables autonomous fault recovery in safety-critical systems. |
Pinout & Package
MPM3807CGLE-18-AEC1-P is housed in a wettable flank QFN-15 package (3mm × 4mm × 1.6mm) with exposed thermal pad, optimized for automated optical inspection (AOI) and enhanced solder joint reliability in automotive reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback reference input | Floating for fixed 1.8V output; internal connection to 0.6V reference eliminates external divider and improves regulation stability. |
| 2 PG | Open-drain power-good indicator | Pulled high when VFB ≥ 90% of 0.6V (≥540mV); pulled low if VFB ≤ 85% (≤510mV) - enables system-level power sequencing and fault detection. |
| 3 VIN | Main input supply | Accepts 2.5V–5.5V; requires local 10µF ceramic decoupling to suppress high-frequency switching noise. |
| 4–6 SW | Switch node | Internally connected to drain of high-side P-MOSFET and inductor - high dv/dt node requiring tight loop layout and ground shielding. |
| 7–9 OUT | Power output | Delivers regulated 1.8V; connects directly to load and output capacitor (recommended 22µF X5R/X7R). |
| 10–11 GND | Signal and power ground | Must be tied to large copper pour and multiple vias to internal ground plane - critical for thermal dissipation and EMI control. |
| 12 EN | Enable control | Active-high logic input (0.9V threshold); internal 2MΩ pull-down allows default-off operation - supports power sequencing with MCU GPIO. |
| 13 SS | Soft-start timing | External capacitor (≥1nF) sets ramp time; 3µA internal charge current enables precise control of inrush current during startup. |
| 14 OUT_S | Output sense & discharge path | Provides controlled discharge of output capacitor during shutdown via internal 150Ω path - prevents voltage hold-up in multi-rail systems. |
| 15 DNC | No-connect terminal | Internally tied to SW; must remain unconnected and un-routed - avoids parasitic coupling and thermal stress. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated power stage | 70mΩ HS + 40mΩ LS MOSFETs + 470nH inductor in single package - eliminates discrete layout complexity and reduces footprint by >40% vs. controller+external components. |
| Wettable flank QFN | Side-wettable leads enable AOI-compatible solder joint inspection - meets automotive process validation requirements for zero-defect manufacturing. |
| Forced CCM (FCCM) | Eliminates discontinuous conduction mode transitions - ensures consistent 2.4MHz operation, lower output ripple, and predictable EMI signature across 0–2A load range. |
| Pre-biased start-up | Starts cleanly even with pre-charged output - essential for hot-swap and multi-phase rail sequencing in infotainment head units. |
| 100% duty cycle capability | Supports low-dropout operation down to VIN − VOUT = 100mV - maintains regulation during cold-crank (e.g., 3.3V rail dropping to 2.5V) without dropout. |

FAQ
What is the purpose of the OUT_S pin on MPM3807CGLE-18-AEC1-P?
The OUT_S pin provides a dedicated discharge path for the output capacitor during shutdown, using an internal 150Ω resistor between OUT_S and GND. This ensures rapid, controlled voltage decay to prevent latch-up or back-powering in multi-rail systems. It is active only when EN is low and does not affect normal operation.
Can MPM3807CGLE-18-AEC1-P operate with input voltage below 2.5V?
No - the device has a hard UVLO threshold of 2.45V (rising) and will not start or sustain regulation below 2.5V input. Below this, the internal bias circuitry cannot energize the gate drivers or control logic, and the part remains in shutdown regardless of EN state.
Is external compensation required for stability with the fixed 1.8V version?
No - the MPM3807CGLE-18-AEC1-P integrates a complete compensation network optimized for its internal power stage and 2.4MHz FCCM operation. No external compensation components are needed, and adding them may destabilize the control loop or degrade transient response.
How does the power-good (PG) signal behave during thermal shutdown?
During thermal shutdown, the PG pin is actively pulled low within 80µs of VFB falling below 85% of 0.6V - indicating loss of regulation due to overtemperature. PG remains low until the junction cools sufficiently, VFB recovers above 90%, and soft-start completes, ensuring reliable fault reporting independent of thermal recovery timing.
What is the minimum recommended soft-start capacitor value?
The minimum recommended soft-start capacitor is 1nF, connected between SS and GND. With the internal 3µA charge current, this yields ~200ms soft-start time. Larger values extend ramp time linearly; values below 1nF risk insufficient inrush limiting and potential PG false triggering.
Does MPM3807CGLE-18-AEC1-P support pre-biased output startup?
Yes - the device initiates soft-start and regulates correctly even when the output is pre-charged to 1.8V before EN assertion. This is enabled by internal circuitry that detects pre-bias and disables the discharge path during startup, preventing reverse current flow into the output capacitor.
What is the significance of the "E" suffix in the top marking?
The "E" in the top marking (e.g., "MP3807C…E") denotes the wettable flank package variant - a mechanical feature where the side walls of the QFN leads are plated to enable automated optical inspection of solder fillets. It is not a functional or electrical variant, but a process-critical packaging specification for automotive production.
