Product details
Overview
MPM4710GPA-Z from Monolithic Power Systems is a fully integrated, synchronous buck-boost power module with built-in inductor, operating from 1.2V to 5.5V input and delivering adjustable 1.5V–5.5V output. It delivers up to 1A continuous output current (2A peak), uses fixed 2MHz switching frequency, and integrates internal compensation, soft start, and power-good indication. It is deployed in optical modules requiring compact, efficient voltage regulation across varying input conditions.
For engineers reviewing the MPM4710GPA-Z datasheet, MPM4710GPA-Z pinout, MPM4710GPA-Z application, or MPM4710GPA-Z equivalent, key selection criteria include its buck-boost topology capability, ECLGA-14 package thermal performance, MODE/SYNC-controlled PSM vs. PWM mode trade-offs, and PG-indicated output regulation status under dynamic load transitions.
Technical Context
The MPM4710 employs current-mode control with fixed 2MHz PWM frequency and automatic mode transition between buck, boost, and buck-boost regions based on VIN/VOUT ratio. Its four-MOSFET H-bridge topology (SWA–SWD) enables seamless regulation when input voltage crosses output voltage-critical for battery-powered systems with decaying supply rails.
Internal VCC regulation draws from the higher of VIN or VOUT, enabling operation down to 1.2V VIN when VOUT sustains bias; UVLO thresholds (1.7V rising, 0.69V falling) and thermal shutdown (160°C) ensure robust startup and fault recovery. The device supports external synchronization via MODE/SYNC and provides hiccup-mode short-circuit protection with dual current limits (2.5A startup / 4.2A steady-state).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology | Synchronous buck-boost with integrated inductor and four internal MOSFETs (SWA–SWD) |
| Input Voltage Range | 1.2V to 5.5V - supports single-cell Li-ion, LiFePO₄, or USB-powered systems with wide rail variation |
| Output Voltage Range | 1.5V to 5.5V - set via external resistor divider on FB pin; enables direct powering of 1.8V/3.3V/5V logic rails |
| Switching Frequency | Fixed 2MHz (±15%) - enables use of <1µH inductors and compact 22µF ceramic output capacitors |
| Continuous Output Current | 1A at TA = 25°C - derates to ~0.8A at 85°C ambient due to thermal resistance (θJA = 29°C/W) |
| Quiescent Current | 25µA - minimizes standby power loss in always-on medical or sensor applications |
| Protection Features | Short-circuit hiccup, thermal shutdown (160°C), input/output overvoltage lockout, and load disconnect during shutdown |
Pinout & Package
ECLGA-14 (2.5mm × 2.5mm × 1.2mm) thermally enhanced land-grid array package with exposed PGND pad for PCB heat sinking and low-inductance high-current routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 14 VIN | Power stage input supply | Connects to input source; must be decoupled with ≥10µF ceramic capacitor near pins |
| 2 EN | Enable control input | Pull high (>1.2V) to activate; internal 1.5MΩ pull-down ensures default-off state |
| 3 MODE/SYNC | Mode selection & clock sync | High = fixed-frequency PWM; low = auto PSM/PWM; external clock accepted for system synchronization |
| 4 PG | Power-good open-drain output | Asserts high when VFB ≥ 91.5% VREF; sinks 3mA at 0.3V - used for system sequencing and fault monitoring |
| 5 VCC | Control-stage supply | Powered internally from higher of VIN or VOUT; requires 1µF ceramic bypass to AGND |
| 6 AGND | Signal ground reference | Must be connected to PGND on PCB; not internally tied - critical for noise-sensitive feedback stability |
| 7 NC | No connect | Not bonded; leave unconnected and un-routed |
| 8 FB | Output voltage feedback | Resistor-divider node; high-impedance input (50nA bias); keep trace short and away from SW nodes |
| 9, 10 VOUT | Regulated output terminal | Delivers regulated voltage; place ≥22µF output capacitors directly between VOUT and PGND |
| 11 SW2 | Test point for internal SW2 node | Connected to internal MOSFETs; floating allowed - not for external circuit connection |
| 12 PGND | Power ground return | High-current return path for power stage; tie to AGND via multiple vias and wide copper pour |
| 13 SW1 | Test point for internal SW1 node | Connected to internal MOSFETs; floating allowed - not for external circuit connection |
Key Features
| Feature | Design Value |
|---|---|
| Integrated inductor + controller | Eliminates external inductor selection, layout sensitivity, and EMI filter complexity - reduces BOM count by ≥3 components |
| Auto buck-boost mode transition | Seamlessly shifts topology without external control or firmware intervention when VIN crosses VOUT - essential for battery discharge curves |
| Internal soft start (1.5ms) | Prevents inrush current and output overshoot during power-up; clamps VSS to VFB+0.3V under overload to avoid instability |
| Dual current limit architecture | 2.5A startup limit suppresses input surge; 4.2A steady-state limit enables full 1A output into 3.3V loads with margin |
| Thermal-aware PG and hiccup recovery | PG remains asserted only during stable regulation; hiccup mode pauses switching for 8ms after SCP, then resumes with controlled SS ramp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost power module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS63802DLAR | 3.5V–18V input; 1.8V–5.5V output; 2A max; 2.1MHz fSW; no integrated inductor | Requires external 1.2µH inductor and additional compensation components; larger solution size | Choose when higher input voltage range or 2A output is required and board space allows discrete magnetics |

FAQ
What is the minimum input voltage required to start up the MPM4710GPA-Z?
The MPM4710GPA-Z requires a minimum 1.8V input voltage to initiate startup (VIN_UVLO_RISING = 1.7V typical). However, if VCC is externally biased above 1.56V, the device can operate down to 1.2V VIN - though output current capability is reduced due to increased MOSFET on-resistance at low VIN.
How does the MODE/SYNC pin affect efficiency and noise performance?
When MODE/SYNC is pulled high, the device operates in fixed-frequency PWM mode across all loads, delivering lower output voltage ripple (<15mVpp) but higher light-load quiescent loss. When pulled low, it enters pulse-skip mode (PSM) under light loads, reducing IQ to ~12µA and improving light-load efficiency - at the cost of higher low-frequency ripple.
Can the MPM4710GPA-Z regulate output voltage when input equals output?
Yes - the MPM4710GPA-Z automatically enters buck-boost mode when VIN ≈ VOUT (e.g., 3.3V ±0.3V), dynamically alternating conduction between buck (SWA/SWB) and boost (SWC/SWD) phases within each switching cycle to maintain regulation without dropout or discontinuity.
What is the role of the AGND and PGND pins, and why must they be connected externally?
AGND is the signal ground reference for error amplifier and feedback circuitry; PGND is the high-current return path for power switches. They are isolated internally to prevent switching noise from corrupting feedback accuracy. PCB layout requires low-impedance connection between them - typically via multiple thermal vias under the exposed PGND pad - to ensure stability and thermal performance.
Does the MPM4710GPA-Z support external synchronization of its switching frequency?
Yes - applying an external clock signal (1MHz–3MHz) to the MODE/SYNC pin synchronizes the internal 2MHz oscillator, eliminating beat frequencies in multi-rail systems. The device accepts CMOS-level clocks and maintains phase alignment across temperature and load variations without requiring additional timing components.
What happens during short-circuit conditions, and how does recovery work?
Under short-circuit, output voltage collapses below 60% of target, triggering hiccup mode: switching halts for ~8ms, then attempts soft restart. If fault persists, it repeats. During recovery, VSS is clamped to VFB+0.3V to prevent overshoot, and negative current limiting (-1A) discharges residual output capacitance before ramp-up resumes.
Is the ECLGA-14 package compatible with standard reflow profiles and automated optical inspection (AOI)?
Yes - the ECLGA-14 (2.5mm × 2.5mm × 1.2mm) package complies with IPC/JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) and supports standard lead-free reflow profiles (peak 260°C). Its top-side marking and coplanar land pattern enable reliable AOI detection of solder joint integrity and component placement.
