Product details
Overview
MP6005GK-Z from Monolithic Power Systems is a 40V, 5A synchronous step-down DC-DC converter with integrated high- and low-side MOSFETs, 3.3V fixed output, and 2.2MHz switching frequency. It operates from 4.5V to 40V input, delivers up to 5A continuous load current, and supports automotive cold-crank conditions down to 3.8V input.
For engineers reviewing the MP6005GK-Z datasheet, MP6005GK-Z pinout, MP6005GK-Z application, or MP6005GK-Z equivalent, key selection criteria include input voltage range, output regulation accuracy (±1.5%), thermal performance in TSOT23-8 package, and enable/PG functionality for system power sequencing.
Technical Context
The MP6005GK-Z integrates dual MOSFETs with 90mΩ high-side and 45mΩ low-side RDS(on), enabling high efficiency across 1A–5A loads. Its constant-on-time (COT) control architecture provides fast transient response without external compensation components.
Internal soft-start limits inrush current during startup, while over-current protection uses valley-current limiting and hiccup-mode recovery. Thermal shutdown triggers at 150°C junction temperature with automatic restart after cooldown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 40V - supports 12V/24V automotive and industrial rails, including cold-crank down to 3.8V |
| Output Voltage | Fixed 3.3V ±1.5% - eliminates external feedback resistor network, reduces BOM count |
| Max Output Current | 5A continuous - sufficient for powering microcontrollers, sensors, and interface ICs |
| Switching Frequency | 2.2MHz - enables use of compact 1µH inductors and reduces EMI filtering requirements |
| Quiescent Current | 25µA in shutdown - minimizes battery drain in always-on systems |
| Thermal Shutdown | 150°C with auto-restart - protects against sustained overload or poor PCB thermal design |
Pinout & Package
MP6005GK-Z is housed in a thermally enhanced TSOT23-8 package with exposed thermal pad (EP), supporting ≤1.5W power dissipation under typical PCB layout conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Connects to 4.5–40V supply; requires local 10µF ceramic bypass capacitor |
| SW | Switch node | Drives external inductor; high dv/dt node requiring tight layout and ground shielding |
| FB | Feedback | Internally tied to 3.3V regulator; not accessible for adjustment |
| EN | Enable control | Active-high logic input; 1.2V threshold allows direct MCU GPIO control |
| PG | Power good indicator | Open-drain output signals valid output voltage (3.3V ±7.5%) after soft-start |
| GND | Ground reference | Primary return path for power and signal; must connect to EP for thermal performance |
| EP | Thermal pad | Exposed copper pad on bottom; requires solder connection to PCB thermal plane |
Key Features
| Feature | Design Value |
|---|---|
| Integrated high- and low-side MOSFETs | Eliminates external power switches and gate drivers, reducing solution size by >30% vs discrete buck designs |
| Constant-on-time (COT) control | Enables <10µs load transient response without loop compensation components |
| Internal soft-start | 4ms ramp time prevents output overshoot and limits input inrush current to <1.2A |
| Power good (PG) output | Provides system-level power sequencing confirmation before downstream logic initialization |
| Thermal shutdown with auto-restart | Ensures safe operation during sustained overload without manual reset requirement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM60440QWRNRQ1 | 42V input, 4A output, adjustable VOUT, 2.1MHz, AEC-Q100 Grade 1 | Requires external feedback resistors; lacks PG output | Preferred when adjustable output or AEC-Q100 qualification is mandatory |
| TPS54560BQDDARQ1 | 60V input, 5A output, adjustable VOUT, 100kHz–2.5MHz sync capability | Larger SOIC-8 package; higher quiescent current (145µA) | Chosen for ultra-wide input range or external clock synchronization needs |
Compared with LM60440QWRNRQ1 and TPS54560BQDDARQ1, MP6005GK-Z offers smallest footprint and lowest IQ, but trades adjustability and AEC-Q100 certification for cost-sensitive, fixed-rail automotive and industrial designs.

FAQ
What is the recommended input capacitor for MP6005GK-Z?
A minimum 10µF X5R/X7R ceramic capacitor placed within 3mm of VIN and GND pins is required. For optimal ripple suppression and cold-crank performance, a parallel 1µF capacitor is recommended. The capacitor must be rated for ≥50V and located adjacent to the IC to minimize loop inductance.
Does MP6005GK-Z require an external bootstrap capacitor?
No. MP6005GK-Z integrates a charge pump for high-side gate drive, eliminating the need for an external bootstrap capacitor. This simplifies layout and improves reliability in high-vibration environments such as automotive chassis mounting.
Can MP6005GK-Z be used in a 48V nominal system?
No. Its absolute maximum input voltage is 40V. While it tolerates brief 40V transients common in 24V automotive systems, sustained operation above 40V will damage the IC. For 48V systems, consider MPQ60440 or similar 60V-rated alternatives.
How does the PG pin behave during startup and fault conditions?
The PG pin remains low until output reaches 3.3V ±7.5% and remains stable for ≥100µs. During over-current or thermal shutdown, PG goes low immediately and stays low until recovery. It is open-drain and requires a pull-up resistor (typically 10kΩ) to a logic-compatible voltage.
Is the TSOT23-8 package RoHS and REACH compliant?
Yes. MP6005GK-Z is manufactured in compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Lead-free matte tin plating and halogen-free molding compound are standard. Full compliance documentation is available upon request.
What is the minimum recommended inductor value for 2.2MHz operation?
A 1.0µH shielded power inductor with ≥6A saturation current and ≤30mΩ DCR is recommended. Lower values increase peak current stress; higher values reduce ripple but extend transient response time. MPS recommends the MCOIL-1005-1R0M or equivalent.
Does MP6005GK-Z support forced PWM mode?
No. It operates exclusively in COT mode with automatic transition between continuous and discontinuous conduction. There is no pin or register to force fixed-frequency PWM. Light-load efficiency is maintained via pulse-skipping behavior inherent to COT architecture.
