Overview
MPM3808GLE-AEC1-Z from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, fully integrated synchronous step-down power module with embedded inductor and dual MOSFETs, delivering up to 3A continuous output current across a 2.5V–5.5V input range, ±1% feedback accuracy, and operation from –40°C to +150°C junction temperature - deployed in automotive camera modules and ADAS sensor rails.
For engineers reviewing the MPM3808GLE-AEC1-Z datasheet, MPM3808GLE-AEC1-Z pinout, MPM3808GLE-AEC1-Z application, or MPM3808GLE-AEC1-Z equivalent, key selection criteria include its wettable-flank QFN-15 package, 2.4MHz switching frequency for EMI control, COT-based transient response, integrated soft-start and power-good signaling, and AAM mode for light-load efficiency in constrained automotive PCB layouts.
Technical Context
The MPM3808GLE-AEC1-Z implements constant-on-time (COT) control with VIN feed-forward, enabling stable 2.4MHz switching across input and load variations while maintaining fast transient response without external compensation. Its internal 470nH inductor and matched 65mΩ/35mΩ HS/LS MOSFETs support high-efficiency buck conversion down to 0.6V output.
It integrates sleep mode (21µA IQ) and Advanced Asynchronous Modulation (AAM) with zero-current detection (50mA threshold) to sustain DCM operation under light loads, plus comprehensive protection including cycle-by-cycle current limiting (4–6A peak), thermal shutdown at 170°C, and hiccup-mode OVP/SCP - all validated per AEC-Q100 Grade 1 requirements.

Pinout & Package
MPM3808GLE-AEC1-Z is housed in a thermally enhanced, wettable-flank QFN-15 package (3mm × 4mm × 1.6mm) with exposed thermal pad connected to GND. The pinout supports compact layout with dedicated power, sense, and control terminals optimized for low-noise automotive power delivery.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback input | Connects to resistor divider for adjustable VOUT; floats for fixed-output versions - referenced to 0.6V internal bandgap for ±1% regulation. |
| 2 PG | Open-drain power-good indicator | Pulled high when VFB ≥ 90% of 0.6V; pulled low at ≤85% - enables system-level power sequencing and fault monitoring. |
| 3 VIN | Main input supply | Accepts 2.5V–5.5V with 2.45V UVLO rising threshold - requires local ceramic decoupling to suppress rail bounce during 3A transients. |
| 4–6 SW | Switch node | Internal high-side P-MOSFET drain tied to integrated inductor - carries high di/dt; must be routed with minimal loop area for EMI control. |
| 7–9 OUT | Power output | Delivers regulated VOUT to load; connects to output capacitor bank - shares thermal pad with GND for low-impedance return path. |
| 10–11 GND | Ground reference | Common return for input/output capacitors and IC substrate - requires multiple vias to inner ground plane for thermal and noise performance. |
| 12 EN | Enable control | Digital on/off control with 0.9V rising / 0.65V falling thresholds and internal 2MΩ pull-down - supports power sequencing in multi-rail systems. |
| 13 SS | Soft-start timing | External capacitor sets ramp rate for VOUT - 1nF minimum yields ~300ms startup; prevents inrush into downstream capacitance. |
| 14 OUT_S | Output voltage sense | High-accuracy remote sensing path for VOUT; also serves as discharge path (150Ω) during shutdown - improves regulation under load variation. |
| 15 DNC | No-connect pad | Internally tied to SW - must remain unconnected and un-routed to avoid parasitic coupling or thermal stress. |

FAQ
What is the function of the OUT_S pin on the MPM3808GLE-AEC1-Z?
The OUT_S pin provides high-accuracy remote sensing of the output voltage for improved regulation under load transients, and simultaneously serves as the internal discharge path (150Ω) to safely bleed stored energy from the output capacitor during shutdown - eliminating need for external discharge circuitry in most automotive implementations.
Does the MPM3808GLE-AEC1-Z support adjustable output voltage?
Yes - the MPM3808GLE-AEC1-Z is the adjustable-output variant; connect a resistor divider from OUT to GND with the FB pin to set VOUT from 0.6V to VIN – 0.5V. The internal 0.6V reference ensures ±1% accuracy across –40°C to +150°C, and the FB pin must be left floating for fixed-output versions like MPM3808GLE-12-AEC1-Z.
How does the AAM mode improve efficiency at light loads?
AAM mode disables forced PWM and enables discontinuous conduction mode (DCM) under light loads using zero-current detection (50mA threshold); this reduces switching losses and cuts quiescent current to 21µA, sustaining >85% efficiency at 1mA output - critical for always-on ADAS sensors drawing microampere standby current.
What is the purpose of the DNC pin (Pin 15)?
Pin 15 is a do-not-connect pad internally tied to the SW node; routing traces or placing vias beneath it creates parasitic inductance and thermal stress that can degrade EMI performance and reliability - it must remain unconnected and excluded from copper pours per MPS layout guidelines.
Can the MPM3808GLE-AEC1-Z operate at 100% duty cycle?
Yes - the device supports 100% duty cycle in dropout mode when VIN approaches VOUT, maintaining regulation without pulse skipping; this is enabled by its constant-on-time architecture and internal high-side P-MOSFET, allowing seamless transition into LDO-like behavior for automotive brown-out resilience.
Is the MPM3808GLE-AEC1-Z RoHS and halogen-free compliant?
Yes - all MPM3808 variants are lead-free, halogen-free, and fully compliant with the EU RoHS directive; MPS publishes green status documentation on its website under Quality Assurance, confirming adherence to JEDEC J-STD-609 moisture sensitivity level 1 and IPC/JEDEC J-STD-020 reflow profiles.
What thermal resistance values apply to the QFN-15 package?
The MPM3808GLE-AEC1-Z QFN-15 package has θJA = 65°C/W and θJC = 14°C/W (JESD51-7, 4-layer board); on the standard EVB (EVM3808-LE-00A), measured values are θJA = 53°C/W and θJC = 10°C/W - these guide heatsink design and maximum ambient temperature derating for 3A continuous operation.
