Product details
Overview
MPM3806GLE-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 1A continuous output current across 2.5V–5.5V input range, featuring 1% FB accuracy, 2.4MHz switching frequency, and -40°C to +150°C junction temperature rating. It serves as a compact, high-efficiency DC-DC converter for automotive ADAS sensors and camera modules requiring minimal external components.
For engineers reviewing the MPM3806GLE-AEC1-Z datasheet, MPM3806GLE-AEC1-Z pinout, MPM3806GLE-AEC1-Z application, or MPM3806GLE-AEC1-Z equivalent, key selection considerations include its adjustable-output configuration (FB pin-based regulation), wettable-flank QFN-15 package for solder-joint inspection, AEC-Q100 qualification for automotive reliability, and COT control architecture enabling fast transient response in space-constrained vehicle subsystems.
Technical Context
The MPM3806GLE-AEC1-Z implements constant-on-time (COT) control with VIN feed-forward, maintaining stable 2.4MHz switching frequency across input and load variations while enabling 100% duty cycle operation for low-dropout regulation. Its internal 75mΩ/45mΩ HS/LS MOSFET pair and 470nH integrated inductor support efficient 1A delivery with minimal thermal rise.
Functional blocks include a 0.6V reference comparator for feedback regulation, open-drain PG signal asserting at 90% VFB, EN-controlled sequencing with 0.9V rising threshold, and advanced asynchronous modulation (AAM) with zero-current detection (50mA threshold) to sustain DCM operation and 21µA sleep-mode IQ under light loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Input voltage range | 2.5V to 5.5V - supports direct connection to automotive 3.3V/5V rails and battery-supplied systems with UVLO at 2.45V (rising) |
| Output current | 1A continuous - sustained without derating at TJ ≤ 150°C on standard 4-layer PCB per EVM3806-LE-00A layout |
| Feedback accuracy | ±1% at 25°C - ensures precise VOUT regulation (e.g., 0.6V reference ±6mV) critical for DSP core supply stability |
| Switching frequency | 2.4MHz nominal - enables use of small external capacitors and reduces EMI fundamental energy above sensitive AM radio bands |
| Quiescent current | 21µA in sleep mode - extends battery life in always-on ADAS vision modules during standby |

Pinout & Package
MPM3806GLE-AEC1-Z is housed in a wettable-flank QFN-15 package (3mm × 4mm × 1.6mm) with exposed thermal pad for enhanced heat dissipation in automotive environments. The package supports automated optical inspection (AOI) of solder joints via side-wettable flanks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback input | Connects to resistor divider for adjustable VOUT; floating for fixed-output variants; referenced to 0.6V internal bandgap |
| 2 PG | Power good indicator | Open-drain output pulled high when VFB ≥ 90% of 0.6V; used for system power sequencing and fault monitoring |
| 3 VIN | Main input supply | Accepts 2.5V–5.5V; requires local ceramic decoupling to suppress high-frequency switching noise |
| 4–6 SW | Switch node | Internal P-channel HS-FET drain connected to integrated inductor; carries high di/dt switching current |
| 7–9 OUT | Regulated output | Delivers up to 1A; connects directly to load and output capacitor; routed with wide copper for low impedance |
| 10–11 GND | Ground reference | Common return for input/output caps and IC substrate; multiple vias required to thermal pad for thermal management |
| 12 EN | Enable control | Digital input with 0.9V turn-on threshold and internal 2MΩ pull-down; supports power sequencing in multi-rail systems |
| 13 SS | Soft-start timing | Accepts ≥1nF capacitor to control VOUT ramp rate and limit inrush current during startup |
| 14 OUT_S | Output sense & discharge | Senses VOUT for regulation and provides 150Ω discharge path to GND when disabled |
| 15 DNC | No-connect | Internally tied to SW; must remain unconnected and un-routed to avoid parasitic coupling or short circuits |

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 |
|---|---|---|---|
| MPM3683-10-AEC1-Z | Higher 2A output, 3.3V–18V input, larger QFN-21 (4mm×4mm), no wettable flank | Better suited for higher-power ADAS ECUs; lacks AOI-friendly package for compact camera modules | Select when >1A output or wider VIN range is required; verify thermal margin on smaller PCBs |
| TPS82084SILR | 1A, 2.5V–6V input, 2.2MHz fSW, QFN-10 (2.5mm×3mm), non-AEC-Q100 | Smaller footprint but unqualified for automotive; lower thermal performance (θJA = 75°C/W) | Consider only for industrial or consumer prototypes; not approved for production automotive use |
Compared with MPM3806GLE-AEC1-Z, the MPM3683-10-AEC1-Z offers higher current and input range at the cost of size and manufacturability, while the TPS82084SILR sacrifices automotive qualification and thermal robustness for footprint reduction-making the MPM3806GLE-AEC1-Z optimal for AEC-compliant, space-constrained 1A applications.

FAQ
What is the function of the OUT_S pin on the MPM3806GLE-AEC1-Z?
The OUT_S pin serves dual functions: it provides output voltage sensing for regulation feedback and acts as the discharge path for the output capacitor when the device is disabled. Internally, it connects to a 150Ω resistor to GND, enabling controlled VOUT ramp-down during shutdown. To block discharge, place a capacitor between OUT_S and VOUT.
Can the MPM3806GLE-AEC1-Z operate with a 2.5V input voltage?
Yes-the MPM3806GLE-AEC1-Z supports input voltages from 2.5V to 5.5V. At 2.5V input, it maintains regulation down to 0.6V output with 100% duty cycle operation, making it suitable for cold-crank scenarios in automotive systems. Efficiency remains >80% at 1A load with VOUT = 1.2V.
How does the Constant-On-Time (COT) control improve transient response?
COT control eliminates traditional error amplifier compensation, enabling immediate high-side FET activation when feedback voltage drops below 0.6V. Combined with VIN feed-forward, this yields sub-10µs load transient recovery (0A→1A) and inherent loop stability without external compensation components.
Is the MPM3806GLE-AEC1-Z pin-compatible with other MPM3806 variants?
Yes-all MPM3806 variants (including fixed-output versions like MPM3806GLE-12-AEC1-Z) share identical QFN-15 pinout and footprint. The only functional difference is FB pin handling: adjustable versions require external resistor divider, while fixed versions float FB and set VOUT internally.
What thermal performance can be expected on a standard 4-layer PCB?
On the EVM3806-LE-00A reference board (6.3cm×6.3cm, 2oz copper, 4-layer), the MPM3806GLE-AEC1-Z achieves θJA = 53°C/W. At 1A load and 3.3V input, case temperature rise is ≤15°C above ambient-well within the -40°C to +150°C TJ rating.
Does the PG signal require an external pull-up resistor?
Yes-the PG pin is open-drain and must be pulled up to a logic-compatible voltage (e.g., 3.3V or 5V) using an external resistor (typically 10kΩ–100kΩ). Without pull-up, PG cannot assert high; floating PG defaults to inactive (low) state.
How is AEC-Q100 Grade 1 qualification verified for this part?
MPM3806GLE-AEC1-Z undergoes full AEC-Q100 stress testing including HTOL (1000h at 150°C), temperature cycling (-40°C to +150°C), ESD (HBM Class 2, CDM Class 2b), and mechanical shock/vibration per automotive requirements-certified by independent lab reports traceable to MPS document MPQ-3806-AEC1.
