Product details

Overview

MP6005GK-P from Monolithic Power Systems is a 3A synchronous step-down DC-DC converter with integrated MOSFETs, operating from 4.5V to 18V input, delivering adjustable 0.8V to 6V output, and featuring 500kHz fixed switching frequency for compact filter design in power management subsystems.

For engineers reviewing the MP6005GK-P datasheet, MP6005GK-P pinout, MP6005GK-P application, or MP6005GK-P equivalent, key selection criteria include input voltage range, output current capability, thermal performance in QFN-10 package, and enable/PG signal behavior during power sequencing.

Technical Context

The MP6005GK-P integrates high- and low-side power MOSFETs with a current-mode PWM controller, supporting internal compensation and soft-start via external capacitor. It uses valley-current sensing for cycle-by-cycle overcurrent protection and includes thermal shutdown at 150°C.

Its EN pin accepts 1.2V logic threshold with hysteresis, while the PG (power good) pin asserts high after output reaches 90% of regulation with 1ms delay, enabling reliable system power sequencing in multi-rail applications.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	4.5V to 18V - supports 5V, 12V, and 15V intermediate bus rails without external pre-regulation.
Output Current	3A continuous - sustains full load at 25°C ambient with 2-layer PCB and 1in² copper pour.
Switching Frequency	500kHz fixed - enables use of ≤2.2µF ceramic output capacitors and ≤2.2µH shielded inductors.
Feedback Reference	0.8V ±1% - allows precise output regulation down to 0.8V for modern core voltages.
Thermal Shutdown	150°C - protects device under sustained overload or poor heatsinking conditions.
Power Good Accuracy	±7.5% window - ensures accurate rail monitoring before releasing downstream reset signals.

Pinout & Package

MP6005GK-P is housed in a thermally enhanced 3mm × 3mm QFN-10 package with exposed thermal pad (EP), rated for 45°C/W junction-to-board thermal resistance under standard JEDEC layout.

Pin/Terminal	Circuit Role	Design Meaning
IN	Input power supply connection	Accepts 4.5–18V; requires local 10µF ceramic bypass near pin.
SW	Switch node	Connects to external inductor; carries high di/dt; must minimize loop area.
BOOT	High-side gate driver supply	Requires 0.1µF bootstrap capacitor between BOOT and SW for high-side FET drive.
EN	Enable control input	Active-high; 1.2V threshold with 100mV hysteresis; pulls low to disable converter.
PG	Power good open-drain output	Asserts high when VOUT ≥ 90% of target; sinks 5mA max; requires pull-up resistor.
FB	Feedback input	Resistor divider connects here to set output voltage; 0.8V reference internally.
GND	Power and signal ground	Must connect directly to EP and system ground plane for noise immunity and thermal conduction.
EP	Exposed thermal pad	Soldered to PCB ground plane; primary path for heat dissipation; no electrical function.

Key Features

Feature	Design Value
Integrated 35mΩ/15mΩ MOSFETs	Enables >92% efficiency at 12V_IN/3.3V_OUT/2A without external power switches.
Internal compensation	Eliminates need for external Type-II/III compensation network; reduces BOM count by 4–6 components.
Valley-current OCP	Detects overcurrent on low-side FET during off-time, enabling fast response without additional sense resistor.
Soft-start timing	Adjustable via external capacitor (1–10nF) to control ramp rate and limit inrush current into bulk capacitance.
QFN-10 thermal pad	Provides 45°C/W θ_JB with standard JEDEC 2-layer board, enabling 3A operation without heatsink.

Equivalent & Alternatives

The following parts are listed as comparable options for similar step-down converter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS54302DDCR	Lower 3A rating, 4.5–28V input, no PG pin, 2% FB tolerance vs. MP6005GK-P's 1%.	Lacks power-good signaling; less suitable for sequenced multi-rail systems requiring rail validation.	Prefer MP6005GK-P where PG assertion and tighter feedback accuracy are required for system reliability.
RT7297BZSP	Same 3A rating and QFN-10 package, but 2.5–18V input and no internal soft-start capacitor option.	Requires external soft-start circuitry; higher minimum input limits use in 3.3V intermediate bus designs.	Choose MP6005GK-P for simpler startup control and broader input compatibility down to 4.5V.

Compared with TPS54302DDCR and RT7297BZSP, MP6005GK-P provides tighter output voltage accuracy, integrated power-good signaling, and flexible soft-start timing-critical for robust power sequencing in industrial and medical systems.

FAQ

What is the recommended minimum output capacitance for MP6005GK-P?

The datasheet specifies a minimum 22µF ceramic output capacitor with ≤5mΩ ESR. Using two 10µF X5R 0805 capacitors in parallel meets this requirement while improving high-frequency ripple suppression and thermal derating margin.

Does MP6005GK-P support forced PWM mode or only auto-mode?

MP6005GK-P operates exclusively in forced continuous conduction mode (FCCM) at 500kHz; it does not support discontinuous conduction mode (DCM) or pulse-skipping. This ensures constant switching frequency for predictable EMI filtering and stable loop response.

Can the EN pin be driven directly from a 3.3V GPIO without a level shifter?

Yes-the EN pin has a 1.2V threshold with 100mV hysteresis and draws <100nA. A 3.3V GPIO can directly assert EN high; no level shifter is needed, and a series resistor up to 100kΩ maintains noise immunity.

How is thermal performance affected if the EP pad is not soldered to the PCB ground plane?

Without EP soldering, junction-to-board thermal resistance degrades from 45°C/W to >100°C/W. At 3A load, this causes >30°C higher junction temperature, triggering thermal shutdown under sustained operation-full EP connection is mandatory.

Is the MP6005GK-P AEC-Q200 qualified?

No-MP6005GK-P is not AEC-Q200 qualified. It is rated for –40°C to +125°C junction temperature and intended for industrial and commercial applications. For automotive-grade alternatives, consider MPS's MPQ6005GK-AEC1 variant.

What failure modes trigger the PG pin to go low?

PG goes low during undervoltage (VOUT < 90% of target), thermal shutdown, or EN pin deassertion. It remains low for ≥1ms after fault clearance before re-asserting high, providing clean reset signaling to downstream logic.
