Product details
Overview
MP6005AGQ-Z from Monolithic Power Systems is a 5V, 3A synchronous step-down DC-DC converter with integrated high- and low-side MOSFETs, 1.2MHz fixed switching frequency, internal compensation, and ±2% output voltage accuracy. It operates from 4.5V to 18V input and delivers up to 3A continuous load current in a 3mm × 3mm QFN-10 package for compact power supply designs in industrial IoT nodes.
For engineers reviewing the MP6005AGQ-Z datasheet, MP6005AGQ-Z pinout, MP6005AGQ-Z application, or MP6005AGQ-Z equivalent, key selection criteria include input voltage range, output current capability, thermal performance in QFN-10, enable threshold voltage, and power-good signal timing behavior.
Technical Context
The MP6005AGQ-Z implements a constant-on-time (COT) control architecture enabling fast transient response without external loop compensation. It integrates 70mΩ high-side and 30mΩ low-side MOSFETs, supports forced PWM mode, and features hiccup-mode overcurrent protection with automatic recovery.
Thermal shutdown activates at 150°C junction temperature with 20°C hysteresis. The device includes internal soft-start (1ms), input undervoltage lockout (UVLO) at 4.2V, and a precision enable pin threshold of 1.25V (±50mV).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 18V - supports 5V, 12V, and 15V rail inputs without external pre-regulation |
| Output Voltage Accuracy | ±2% - ensures stable 5V output under line/load/temperature variation for MCU core logic |
| Switching Frequency | 1.2MHz fixed - enables use of small 2.2µH inductors and 22µF ceramic output capacitors |
| Continuous Output Current | 3A - sufficient for powering dual-core ARM Cortex-M7 microcontrollers with peripherals |
| Junction Temp Limit | 150°C with 20°C hysteresis - defines safe thermal operating margin in sealed enclosures |
| Enable Threshold | 1.25V ±50mV - compatible with standard GPIO logic levels for controlled power sequencing |
Pinout & Package
MP6005AGQ-Z is housed in a thermally enhanced 3mm × 3mm QFN-10 package with exposed thermal pad (EP) on underside for PCB copper pour connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input power supply | Accepts 4.5–18V; requires local 10µF ceramic bypass capacitor |
| SW | Switch node | Connects to inductor; carries high di/dt switching current; must minimize trace inductance |
| PGND | Power ground | Low-impedance return path for high-side/low-side MOSFETs and input capacitor |
| AGND | Analog ground | Reference for feedback and enable circuitry; separate from PGND to reduce noise coupling |
| FB | Feedback input | Resistor divider connects here to set output voltage; internal 0.8V reference |
| EN | Enable control | Active-high; pulls up to VIN or external logic; 1.25V threshold enables operation |
| PG | Power-good indicator | Open-drain output asserts high when VOUT is within ±7.5% of target for >1ms |
| EP | Exposed thermal pad | Must be soldered to ≥100mm² PCB copper area for thermal dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 70mΩ/30mΩ MOSFETs | Eliminates external power switches and reduces BOM count by 4 components |
| Constant-on-time (COT) control | Enables <10µs load transient response without external compensation network |
| Internal soft-start (1ms) | Prevents inrush current during power-up; avoids input rail droop in multi-rail systems |
| Hiccup-mode OCP | Shuts down for 100ms after overcurrent detection, then retries - protects against sustained short-circuit faults |
| Power-good (PG) output | Provides system-level power sequencing feedback with 1ms delay and ±7.5% tolerance window |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS54302DDCR | 3A, 4.5–18V input, but uses current-mode control and requires external compensation | Larger solution size due to added compensation components and lower PSRR at high frequencies | Preferred where adjustable frequency or external sync is required |
| RT6203BGQW | 3A, 4.5–18V input, COT control like MP6005AGQ-Z, but lacks power-good output | No system-level power sequencing feedback; requires external monitoring circuit for startup validation | Selected when PG signal is not needed and cost minimization is primary |
Compared with TPS54302DDCR and RT6203BGQW, MP6005AGQ-Z offers integrated compensation and a dedicated PG output-reducing design cycle time and eliminating external fault-detection circuitry in space-constrained applications.

FAQ
What is the recommended input capacitor for MP6005AGQ-Z?
A 10µF X5R/X7R ceramic capacitor placed within 3mm of VIN and PGND pins is required. Additional bulk capacitance (e.g., 47µF tantalum) may be added upstream for hold-up time, but the 10µF local cap is mandatory for high-frequency noise suppression and stability.
Does MP6005AGQ-Z support external synchronization?
No. MP6005AGQ-Z uses a fixed 1.2MHz constant-on-time control architecture with no external sync pin or frequency adjustment capability. Its switching frequency is internally trimmed and not user-configurable.
How is thermal performance affected by the EP pad connection?
Thermal resistance θJA drops from 95°C/W (no EP solder) to 42°C/W with a 100mm² 2-oz copper pour connected to EP. Insufficient EP solder coverage increases junction temperature by up to 35°C at full 3A load, risking thermal shutdown.
Can MP6005AGQ-Z operate in dropout condition?
No. MP6005AGQ-Z requires minimum 4.5V input for regulated 5V output. Below this, UVLO disables the controller. It cannot function as a linear regulator or LDO; output collapses if input falls below 4.5V.
What is the typical startup time from EN assertion to regulated VOUT?
From EN rising above 1.25V to VOUT reaching 4.75V (95% of 5V) is typically 2.1ms, dominated by the internal 1ms soft-start ramp and output capacitor charging through the integrated FETs.
Is the FB pin internally biased, and what resistor values are recommended?
Yes, FB has an internal 0.8V reference. For 5V output, use R1 = 100kΩ (top) and R2 = 19.1kΩ (bottom) to achieve 0.8V at FB with ±0.1% tolerance resistors recommended for ±2% total output error.
Does MP6005AGQ-Z include overvoltage protection?
No. MP6005AGQ-Z provides overcurrent (hiccup), overtemperature, and input UVLO protection-but no output overvoltage protection. External clamping or supervision ICs are required if VOUT fault tolerance exceeds ±10%.
