Product details
Overview
MPM3808CGLE-18-AEC1-Z from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, fully integrated synchronous step-down power module with embedded inductor and MOSFETs, delivering up to 3A continuous output at fixed 1.8V with ±2% regulation accuracy over -40°C to +150°C junction temperature, 2.5V–6V input range, and 2.4MHz switching frequency for compact automotive power rails.
For engineers reviewing the MPM3808CGLE-18-AEC1-Z datasheet, MPM3808CGLE-18-AEC1-Z pinout, MPM3808CGLE-18-AEC1-Z application, or MPM3808CGLE-18-AEC1-Z equivalent, this page delivers verified technical context, validated pin functions, confirmed automotive-grade thermal and EMC performance, and real-world substitution guidance for ADAS camera modules and infotainment subsystems.
Technical Context
The MPM3808CGLE-18-AEC1-Z uses constant-on-time (COT) control with VIN feed-forward to maintain stable 2.4MHz switching across 2.5V–6V input and full 0–3A load range, enabling fast transient response without external compensation. Its FCCM operation eliminates mode transitions and minimizes output ripple.
It integrates a 470nH inductor with 25mΩ DCR, 50mΩ high-side and 26mΩ low-side MOSFETs, and a dedicated OUT_S sense pin for accurate discharge control. The PG signal asserts high when VFB exceeds 90% of 0.6V reference, with 70µs deglitching and open-drain output requiring external pull-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 1.8V ±2% (1.764V–1.836V), factory-trimmed for automotive-grade stability without external feedback resistors. |
| Max output current | 3A continuous, supported by integrated 470nH inductor and matched 50mΩ/26mΩ MOSFET pair for thermal efficiency. |
| Input voltage range | 2.5V to 6V - enables direct connection to automotive 3.3V/5V rails and battery-supervised systems with UVLO at 2.45V rising threshold. |
| Switching frequency | 2.4MHz nominal (2.0–2.7MHz range), enabling small external capacitors and meeting CISPR-25 Class 5 EMI requirements via MeshConnect™ flip-chip packaging. |
| Junction temperature | -40°C to +150°C operating range, validated per AEC-Q100 Grade 1, with thermal shutdown at 170°C and 20°C hysteresis. |
| Protection features | Cycle-by-cycle peak/valley current limiting (5A/3A), hiccup-mode short-circuit protection, output OVP (115% of VREF), and 100% duty cycle LDO mode. |
| Package | QFN-15 (3mm × 4mm × 1.6mm) with wettable flanks for automated optical inspection (AOI) and enhanced solder joint reliability in automotive reflow profiles. |
Pinout & Package
MPM3808CGLE-18-AEC1-Z is housed in a thermally optimized QFN-15 (3mm × 4mm × 1.6mm) package with exposed thermal pad and wettable flank sidewalls for automotive-grade solder joint inspection and thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback reference | Floating in fixed-output configuration; internal resistor divider sets 1.8V output - no external components required. |
| 2 PG | Power good indicator | Open-drain output pulled high when VFB ≥ 90% of 0.6V; asserts low during undervoltage or startup - requires external pull-up resistor. |
| 3 VIN | Main input supply | Accepts 2.5V–6V; connects to bulk decoupling capacitor - UVLO ensures safe start-up above 2.45V. |
| 4–6 SW | Switch node | Internal high-side P-MOS drain connected to integrated inductor - carries high di/dt switching current; requires tight layout to minimize EMI. |
| 7–9 OUT | Regulated output | Delivers 1.8V/3A to load; connects directly to output capacitor and load - low-ESR ceramic caps recommended for ripple suppression. |
| 10–11 GND | Power ground | Common return for input/output capacitors and IC substrate - must be tied to large copper pour with multiple vias to inner ground plane. |
| 12 EN | Enable control | Digital input with 0.9V rising / 0.65V falling thresholds; internal 2MΩ pull-down enables default-off behavior for safety-critical sequencing. |
| 13 SS | Soft-start timing | External capacitor sets ramp time (e.g., 100nF yields ~20ms soft-start); supports pre-biased start-up even with existing VOUT voltage. |
| 14 OUT_S | Output sense & discharge | Senses VOUT for regulation and provides 120Ω discharge path to GND during shutdown - prevents floating rail in multi-rail systems. |
| 15 DNC | No-connect terminal | Internally tied to SW node - must remain unconnected and un-routed to avoid parasitic coupling or solder bridging. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments TPSM84203 | Fixed 1.8V output, 2.2MHz fSW, 3A rating, but lacks AEC-Q100 qualification and wettable flanks; uses external compensation. | Targeted at industrial/commercial DC/DC needs - not certified for automotive safety-critical subsystems. | Select only if AEC-Q100 is not required and board space allows larger external components. |
| Analog Devices LTM4624 | 1.8V fixed option, 3A, 2.5MHz, AEC-Q100 Grade 1, but larger 6.25mm × 6.25mm × 1.82mm package and higher quiescent current (2.5mA vs 0.65mA). | Used in high-reliability avionics and military systems where size is secondary to long-term parametric stability. | Prefer when extended temperature validation beyond +150°C or MIL-STD-883 screening is mandated. |
Compared with TPSM84203 and LTM4624, the MPM3808CGLE-18-AEC1-Z delivers optimal balance of automotive qualification, compact QFN-15 footprint, ultra-low IQ (650µA), and integrated EMC-optimized design - making it the preferred choice for cost-sensitive, space-constrained ADAS camera and V2X modules.

FAQ
What is the purpose of the OUT_S pin on the MPM3808CGLE-18-AEC1-Z?
The OUT_S pin serves dual functions: it provides precision output voltage sensing for regulation feedback and activates an internal 120Ω discharge path to ground during shutdown. This ensures rapid, controlled discharge of the output capacitor - preventing residual voltage that could interfere with downstream logic sequencing or cause latch-up in multi-rail systems.
Does the MPM3808CGLE-18-AEC1-Z require external compensation components?
No. The device integrates a complete compensation network internally, eliminating the need for external resistors or capacitors on the FB node. This is enabled by its constant-on-time (COT) control architecture and factory-trimmed fixed 1.8V output - reducing design complexity and improving production yield in automotive applications.
How does the power-good (PG) signal behave during startup and fault conditions?
The PG pin remains low until VFB reaches 90% of the 0.6V internal reference (i.e., 0.54V), then pulls high via open-drain output after 70µs deglitching. It asserts low again if VFB drops below 85% (0.51V) - providing reliable indication of valid regulation and enabling safe system boot sequencing or fault logging in microcontrollers.
Can the MPM3808CGLE-18-AEC1-Z operate with a 2.5V input and still deliver 3A at 1.8V?
Yes. The device supports full 3A output across its entire 2.5V–6V input range, including at minimum VIN. At 2.5V input, the 100% duty cycle capability ensures regulation is maintained, though efficiency drops to ~82% (per typical curves) due to higher conduction losses in the integrated MOSFETs.
Is the MPM3808CGLE-18-AEC1-Z compatible with standard lead-free reflow profiles?
Yes. The QFN-15 package with wettable flanks is qualified for JEDEC J-STD-020D Level 1 moisture sensitivity and supports peak reflow temperatures up to 260°C. Its thermal pad design and copper pillar flip-chip construction ensure robust solder joint formation under automotive-grade reflow profiles with ramp rates up to 3°C/s.
What failure protections are active during short-circuit events?
Upon short-circuit detection, the device triggers hiccup-mode protection: it disables switching, discharges the SS capacitor, waits for recovery, then attempts restart. Concurrently, valley current limiting (3A) and peak current limiting (5A) prevent MOSFET destruction, while thermal shutdown at 170°C provides final overtemperature defense.
How is electromagnetic compatibility (EMC) addressed in this module?
EMC is addressed through FCCM operation (eliminating frequency modulation noise), MeshConnect™ flip-chip packaging (reducing switching loop inductance), integrated inductor shielding, and optimized internal routing. These features enable compliance with CISPR-25 Class 5 radiated emissions limits without external ferrite beads or complex filter layouts.
