Product details
Overview
MPQ4430GLE-AEC1-P from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, synchronous step-down DC/DC converter with integrated 90mΩ high-side and 40mΩ low-side MOSFETs, delivering up to 3.5A output current across a 3.3V–36V input range. It features programmable switching frequency (350kHz–2.5MHz), 10μA light-load quiescent current in AAM mode, and wettable flank QFN-16 (3mm×4mm) packaging-designed for automotive infotainment power rails and ADAS camera modules.
For engineers reviewing the MPQ4430GLE-AEC1-P datasheet, MPQ4430GLE-AEC1-P pinout, MPQ4430GLE-AEC1-P application, or MPQ4430GLE-AEC1-P equivalent, key selection criteria include cold-crank low-dropout operation, valley-current OCP with hiccup protection, PG indicator timing (30µs deglitch), and SYNC-controlled CCM/AAM mode selection under automotive thermal constraints (–40°C to +125°C TJ).
Technical Context
The MPQ4430GLE-AEC1-P implements current-mode PWM control with valley-current over-current protection and adaptive dead-time management to prevent shoot-through between its integrated high- and low-side MOSFETs. Its advanced asynchronous mode (AAM) dynamically scales switching frequency below 10mA load to minimize gate drive and switching losses.
It supports external clock synchronization (350kHz–2.5MHz), selectable in-phase/180° out-of-phase alignment via PHASE pin, and dual-mode operation: forced CCM for low-noise EMI-sensitive applications or AAM for ultra-low-IQ battery backup systems. The BIAS pin enables efficiency optimization by powering internal regulators from an external 5V–18V rail.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.3V to 36V - supports full automotive battery range including cold-crank (4.5V) and load-dump (40V abs max). |
| Output Current | 3.5A continuous - sustained at full load with θJA = 43°C/W on EV4430-L-00A PCB; derates above +85°C ambient. |
| Quiescent Current | 10μA in AAM sleep mode - enables >1-year battery hold-up in always-on vehicle telematics without recharge. |
| Switching Frequency | 350kHz to 2.5MHz programmable via FREQ resistor - allows EMI tuning and inductor size optimization (e.g., 4.7μH @ 450kHz, 1.0μH @ 2.2MHz). |
| Feedback Reference | 0.800V ±1% - sets output accuracy for fixed versions (e.g., MPQ4430GLE-38-AEC1: 3.8V ±2.5%) and enables precision adjustable designs. |
| Power Good Threshold | ±10% VOUT window with 30μs rising / 50μs falling deglitch - ensures reliable system reset sequencing in safety-critical ECUs. |
| Thermal Shutdown | 170°C with 20°C hysteresis - protects against sustained overload or poor heatsinking in enclosed junction boxes. |
Pinout & Package
MPQ4430GLE-AEC1-P is housed in a wettable flank QFN-16 package (3mm × 4mm, 0.5mm pitch), enabling automated optical inspection (AOI) of solder joints in automotive production lines. Exposed thermal pad (Pin 13 AGND) must be soldered to PCB ground plane for thermal performance (θJC = 5°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 PHASE | Synchronization phase select | Drives high for in-phase sync; low for 180° out-of-phase - critical for multi-rail interleaving to reduce input ripple. |
| 2 VIN | Main input supply | Accepts 3.3V–36V; requires local 10μF ceramic decoupling within 3mm of pin to suppress switching noise. |
| 3,10 SW | Switch node | High dv/dt node connecting internal HS/LS MOSFETs; layout must minimize loop area to meet CISPR25 Class 5 EMI limits. |
| 4,9 PGND | Power ground return | Separate from AGND; connects directly to thermal pad and high-current inductor return path to avoid ground bounce. |
| 5 EN | Enable control | Active-high logic (1.05V threshold); hysteresis prevents chatter during slow-rising battery inputs during ignition. |
| 6 SYNC | Frequency sync & mode select | Configures CCM (SYNC ≥1.8V at startup) or AAM (SYNC ≤0.4V/floating); also accepts external clock for EMI spread-spectrum alignment. |
| 7 PG | Open-drain power-good flag | Signals valid regulation after soft-start; sinks 2mA max; requires external pull-up to system rail (e.g., 3.3V). |
| 8 BIAS | External bias supply | Optional 5V–18V input to bypass internal LDO - reduces power loss by ~150mW at 3.5A, improving full-load efficiency. |
| 11 BST | Bootstrap supply | Requires 0.1μF X7R ceramic capacitor to SW; enables high-side gate drive without external charge pump. |
| 12 VCC | Internal regulator output | 5V regulated supply for control circuitry; requires ≥1μF ceramic decoupling close to pin to stabilize gate drivers. |
| 13 AGND | Analog ground reference | Low-noise reference for FB, SS, and error amplifier; must connect to PGND only at single point near VCC capacitor. |
| 14 SS | Soft-start timing | 10μA current source charges external capacitor; 0.7ms internal default if floating - prevents inrush into downstream capacitors. |
| 15 FB | Feedback voltage sense | 0.800V reference; for fixed-output variants (e.g., -38/-5), connect directly to VOUT; for adjustable, use resistor divider. |
| 16 FREQ | Frequency programming | Resistor-to-GND sets fSW: 180kΩ → 475kHz, 82kΩ → 1MHz, 27kΩ → 2.5MHz - enables precise EMI band placement. |
Key Features

FAQ
What is the purpose of the BIAS pin on MPQ4430GLE-AEC1-P?
The BIAS pin accepts an external 5V–18V supply to power the internal gate drivers and control circuitry, bypassing the internal LDO. This reduces power dissipation by ~150mW at 3.5A output, improving full-load efficiency by up to 1.2% and lowering die temperature in thermally constrained layouts.
How does the PHASE pin affect multi-rail synchronization?
The PHASE pin selects whether the internal oscillator aligns in-phase or 180° out-of-phase with the external SYNC clock. When multiple MPQ4430GLE-AEC1-P devices drive parallel rails, configuring one in-phase and another out-of-phase halves input ripple current, reducing bulk capacitor stress and EMI filter size.
Can MPQ4430GLE-AEC1-P operate reliably during automotive cold-crank conditions?
Yes. Its low dropout mode maintains regulation down to VIN = VOUT + 0.5V, and the 3.3V–36V input range covers cold-crank dips to 4.5V. Combined with valley-current OCP and hiccup mode, it sustains operation and recovers safely without latch-up or thermal shutdown during extended cranking events.
What is the minimum recommended soft-start time using the SS pin?
The SS pin sources a precise 10μA current into an external capacitor. To achieve a 2ms soft-start, use a 20nF capacitor (tSS ≈ 2×CSS×0.8V/10μA). Floating SS enables the internal 0.7ms default, but external control prevents inrush into large downstream capacitance (>1000μF) in infotainment power trees.
Does MPQ4430GLE-AEC1-P require external compensation components?
No. The MPQ4430GLE-AEC1-P uses internal type-II compensation optimized for standard 4.7μH inductors and ceramic output capacitors. Stability is guaranteed across the full 3.3V–36V input range and 10mA–3.5A load range without external compensation networks.
How is the wettable flank feature implemented in the QFN-16 package?
The wettable flank variant exposes solderable metal on the vertical sidewalls of all perimeter pins, enabling automated optical inspection (AOI) of solder fillet height and coplanarity. This meets IPC-A-610 Class 3 requirements for automotive electronics and improves first-pass yield in reflow processes.
What failure modes does the hiccup-mode OCP protect against?
Hiccup-mode OCP disables switching for 10ms after three consecutive valley-current limit trips, then attempts restart. This prevents thermal runaway during sustained short circuits, inductor saturation, or output capacitor failure-reducing average fault current to <50mA and enabling safe system-level fault isolation.
