Product details
Overview
MPM3807GLE-AEC1-Z from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, fully integrated synchronous step-down power module with built-in inductor and MOSFETs, delivering up to 2A continuous output current, 2.5V–5.5V input range, and 1% feedback accuracy. It operates across –40°C to +150°C junction temperature and features constant-on-time (COT) control for fast transient response in automotive ADAS sensors and camera modules.
For engineers reviewing the MPM3807GLE-AEC1-Z datasheet, MPM3807GLE-AEC1-Z pinout, MPM3807GLE-AEC1-Z application, or MPM3807GLE-AEC1-Z equivalent, key selection criteria include its wettable-flank QFN-15 package, 2.4MHz switching frequency, integrated 470nH inductor, 70mΩ/40mΩ internal MOSFETs, and AAM mode for light-load efficiency in space-constrained automotive subsystems.
Technical Context
The MPM3807GLE-AEC1-Z implements VIN feed-forward constant-on-time (COT) control with a fixed minimum off-time of 80ns, enabling stable 2.4MHz operation across 2.5V–5.5V input and load transients. Its internal 0.6V reference and 1% FB accuracy support precise regulation down to 0.6V output.
It integrates a 470nH power inductor (±20%), 70mΩ high-side P-channel and 40mΩ low-side N-channel MOSFETs, and a dedicated OUT_S pin for controlled output discharge via a 150Ω internal path-enabling rapid VOUT ramp-down during shutdown in safety-critical automotive systems.
Key Specifications

Pinout & Package
MPM3807GLE-AEC1-Z is housed in a thermally enhanced, wettable-flank QFN-15 package (3mm × 4mm × 1.6mm) with exposed thermal pad. Pin functions are validated per MPS datasheet Rev. 1.0 (2022).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback input | Connects to resistor divider for adjustable VOUT; floats in fixed-output variants; referenced to 0.6V internal bandgap |
| 2 PG | Open-drain power-good indicator | Pulled high when VFB ≥ 90% of 0.6V; pulled low when VFB ≤ 85%; requires external pull-up for logic-level signaling |
| 3 VIN | Main input supply | Accepts 2.5V–5.5V; requires local ceramic decoupling; UVLO rising threshold = 2.45V |
| 4–6 SW | Switch node | Internal connection to high-side MOSFET drain and integrated inductor; carries high di/dt switching current |
| 7–9 OUT | Power output | Delivers regulated VOUT to load; connects directly to output capacitor and load ground return |
| 10–11 GND | Ground reference | Low-impedance return for input/output capacitors and IC core; must be tied to large copper plane with multiple vias |
| 12 EN | Enable control | Digital on/off control: >0.9V = active, <0.65V = shutdown; includes 2MΩ internal pull-down |
| 13 SS | Soft-start timing | Capacitor-to-ground sets startup slew rate; min CSS = 1nF; prevents inrush into downstream capacitance |
| 14 OUT_S | Output sense & discharge | Senses VOUT for regulation; activates internal 150Ω discharge path to GND during shutdown |
| 15 DNC | No-connect | Internally tied to SW; must remain unconnected and un-routed to avoid parasitic coupling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down power module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS82084SILR | 2A, 2.5V–6V input, 1.8MHz, integrated inductor, but only rated to +125°C TJ and lacks AEC-Q100 qualification | Targeted at industrial/commercial portable devices-not certified for automotive under-hood deployment | Select only for non-automotive designs where AEC-Q100 and 150°C operation are not required |
| MAX20010CATP/V+T | 2.5A, 3V–5.5V input, 2.2MHz, AEC-Q100 Grade 1, but uses external inductor and larger 4mm × 4mm package | Requires additional magnetics and occupies more board area; better suited for designs needing higher peak current margin | Choose when >2A peak load or external inductor flexibility outweighs size and integration benefits |
Compared with TPS82084SILR and MAX20010CATP/V+T, the MPM3807GLE-AEC1-Z uniquely combines AEC-Q100 Grade 1, 150°C operation, wettable flanks, and fully integrated magnetics in a 3mm × 4mm footprint-making it optimal for space- and reliability-constrained automotive camera and sensor nodes.

FAQ
What is the function of the OUT_S pin on the MPM3807GLE-AEC1-Z?
The OUT_S pin serves dual roles: it provides precise output voltage sensing for regulation feedback and activates an internal 150Ω discharge path to GND during shutdown. This ensures rapid, controlled discharge of the output capacitor-critical for meeting automotive safety requirements like ISO 26262 ASIL-B fault response timing.
Does the MPM3807GLE-AEC1-Z support adjustable output voltage?
Yes-the MPM3807GLE-AEC1-Z is the adjustable-output variant. Its FB pin accepts an external resistor divider to set VOUT from 0.6V up to VIN − 0.5V. The internal 0.6V reference and ±1% accuracy enable precise regulation; fixed-output versions (e.g., -12-AEC1) require floating the FB pin.
How does the constant-on-time (COT) control improve transient response?
COT control eliminates traditional error amplifier compensation, enabling immediate response to load steps. When VFB drops below 0.6V, the high-side MOSFET turns on for a time determined by VIN/VOUT, ensuring sub-microsecond recovery-demonstrated in datasheet load-transient waveforms showing <10mV deviation at 1A/µs slew rates.
What is the purpose of the "DNC" pin (Pin 15) on the QFN-15 package?
Pin 15 is designated "Do Not Connect" and is internally bonded to the SW node. Routing traces or placing vias under this pad introduces parasitic inductance and risk of shorting the switch node. It must remain unconnected and excluded from copper pours per MPS layout guidelines to maintain EMI performance and reliability.
Can the MPM3807GLE-AEC1-Z operate at 100% duty cycle?
Yes-it supports 100% duty cycle in dropout conditions (e.g., VOUT = 3.3V with VIN = 3.4V), functioning like an LDO. This is enabled by its synchronous rectifier architecture and valley-current detection, allowing uninterrupted regulation even when input approaches output voltage-essential for automotive cold-crank scenarios.
Is the integrated inductor in the MPM3807GLE-AEC1-Z shielded?
Yes-the integrated 470nH inductor uses a molded, shielded construction that contains magnetic flux within the module body. This minimizes coupling to adjacent signal traces and meets CISPR-25 radiated emissions requirements without external shielding cans-verified in MPS EVM test reports.
What is the recommended soft-start capacitor value for the SS pin?
MPS specifies a minimum 1nF capacitor between SS and GND. A 2.2nF capacitor yields ~4ms soft-start time, limiting inrush current to <1.5A during startup into a 22µF output capacitor-preventing input rail sag and avoiding false UVLO triggering in multi-rail automotive systems.
