Product details
Overview
MP2930GQK-LF-P from Monolithic Power Systems is a 4-phase synchronous buck PWM controller for microprocessor core voltage regulation, featuring 8-bit DAC-based VR10/VR11 dynamic voltage identification (VID), dual-edge PWM for fast load transient response, ±50 µA current-sense accuracy per channel, and integrated voltage droop compensation. It targets high-current desktop/server CPU power delivery with precision current balancing and DCR/resistor current sensing.
For engineers reviewing the MP2930GQK-LF-P datasheet, MP2930GQK-LF-P pinout, MP2930GQK-LF-P application, or MP2930GQK-LF-P equivalent, key selection criteria include phase configurability (2/3/4-phase), VID code compatibility (VR11 vs extended VR10), 6.25 mV/bit DAC resolution, thermal monitoring via TM pin, and interoperability with MPS Intelli-phase drivers like MP86961.
Technical Context
The MP2930 implements interleaved multiphase control with programmable channel count (2/3/4) via PWMx pin strapping, using dual-edge modulation to reduce output capacitor requirements during load transients. Its remote-sense amplifier provides 20 MHz bandwidth and differential VSEN/RGND inputs for accurate output voltage regulation at the load.
Current sensing supports both inductor DCR and discrete resistor methods, with cycle-by-cycle peak-current limiting (120 µA per channel) and average-current OCP (72–98 µA). Voltage droop is implemented by injecting IAVG-proportional current into the FB node, enabling programmable load-line impedance matching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Phase Configuration | 2-, 3-, or 4-phase selectable via PWM3/PWM4 pin strapping; enables scalable current handling and ripple reduction. |
| VID Resolution | 6.25 mV per bit over 8-bit ID input; supports precise dynamic voltage scaling for VR10 (extended) and VR11 protocols. |
| Switching Frequency | Adjustable 80 kHz to 1 MHz via FS pin resistor; typical 250 kHz at RT = 100 kΩ for balanced efficiency and transient response. |
| Current Sensing Accuracy | ±50 µA typical sensed current tolerance (IDROOP); ensures <±1% load-line error under DCR sensing conditions. |
| Voltage Droop Range | Programmable via external RFB; achieves load-line impedance matching per Equation (8) for stable CPU voltage under dynamic current. |
| OVP Threshold | 1.275 V before valid ID; DAC + 175 mV after valid ID; prevents processor damage during startup or fault events. |
| Thermal Monitoring | TM pin accepts NTC thermistor for inductor temperature sensing; VR_FAN/VR_HOT open-drain outputs trigger fan or shutdown at defined thresholds. |
Pinout & Package
MP2930GQK-LF-P is housed in a 40-pin QFN package (6 mm × 6 mm, 0.5 mm pitch) with exposed thermal pad. Pin numbering follows standard counter-clockwise layout from top-left corner (Pin 1 = ID6).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–8, 40 | ID[0:7] inputs | 8-bit VID code interface; internal 45 µA pull-up enables direct connection to open-drain CPU VID outputs. |
| 9 | OFS | DC offset programming pin; connects to VCC or GND to inject ±150 mV offset between REF and DAC for fine-tuning no-load voltage. |
| 10–11 | DAC / REF | DAC reference output and error amplifier inverting input; 0.1 µF capacitor stabilizes DAC transitions during VID changes. |
| 14 | IDROOP | Average-channel current mirror output; sources current proportional to total load for droop implementation at FB node. |
| 15–17 | VDIFF / RGND / VSEN | Differential remote sense interface; rejects PCB trace IR drop to regulate voltage precisely at CPU pins. |
| 18 | SD | Shutdown signal for Intelli-phase drivers (e.g., MP86961 EN); pulled low during fault or shutdown to force Hi-Z MOSFET state. |
| 20, 25–26, 31 | PWM1–PWM4 | Phase PWM outputs; PWM3/PWM4 tied to VCC configures 2-/3-phase operation; all support dual-edge modulation. |
| 21–24, 27–29, 30 | ISENx± | Differential current sense inputs per phase; supports DCR or resistive sensing with matched gain for channel balancing. |
| 32–33 | EN_PWR / EN_VTT | Power sequencing enable inputs; require >0.875 V to initiate soft-start; coordinate timing with VCC and VTT rails. |
| 34–35 | FS / SS | Frequency set (RT-to-GND) and soft-start ramp rate (RSS-to-GND); enable independent optimization of switching speed and startup behavior. |
| 36–39 | VR_RDY / VR_FAN / VR_HOT / TM | Status and thermal monitoring outputs; open-drain logic signals for system-level fault reporting and thermal management. |
Key Features
| Feature | Design Value |

FAQ
What is the recommended current-sense method for MP2930GQK-LF-P in high-efficiency server applications?
Inductor DCR sensing is recommended for server applications due to zero power loss and inherent thermal compensation when paired with a PTC resistor in the RC network. The MP2930's DCR sensing path supports time-constant matching (L/DCR = R×C), achieving ±1% current measurement accuracy across –40°C to +125°C without additional components.
How does MP2930GQK-LF-P implement voltage droop, and what external components are required?
MP2930GQK-LF-P implements voltage droop by sourcing current from the IDROOP pin-proportional to average channel current-into the FB node through an external resistor RFB. No op-amp or additional IC is needed; droop slope is set solely by RFB value and active phase count per Equation (8) in the datasheet.
Can MP2930GQK-LF-P be used with non-MPS gate drivers, and what interface requirements must be met?
Yes, MP2930GQK-LF-P can drive third-party gate drivers via its PWM1–PWM4 outputs, which are CMOS-compatible (0.5 V low / 4.3 V high thresholds). Drivers must accept 5 V logic levels, support Hi-Z state during shutdown (controlled via SD pin), and tolerate dual-edge timing-verified with TI UCC27282 and Infineon IRS2007STRPBF.
What is the function of the OFS pin, and how does it affect output voltage calibration?
The OFS pin allows ±150 mV DC offset injection between DAC and REF pins to correct board-level voltage drops or margin testing. Connecting OFS to VCC generates positive offset (regulated 1.6 V across ROFS); connecting to GND yields negative offset (regulated 0.4 V), enabling fine-tuning without modifying feedback resistors.
How does MP2930GQK-LF-P handle invalid or missing VID codes during startup?
If no valid VR10/VR11 ID code is detected after the td3 delay (~86 µs minimum), MP2930GQK-LF-P forces VR_RDY low and halts regulation. Recovery requires cycling EN_PWR, EN_VTT, or VCC below POR-falling threshold (3.7–4.2 V); VID code changes alone do not reset the controller.
Is MP2930GQK-LF-P RoHS-compliant and lead-free, and what is its moisture sensitivity level?
Yes, MP2930GQK-LF-P is fully RoHS-6 compliant and lead-free, with MSL Level 3 rating (floor life 168 hours at 30°C/60% RH). The "-LF" suffix confirms lead-free finish; reflow profile must follow J-STD-020D with peak temperature ≤260°C and time above 217°C limited to 60–150 seconds.
What thermal protection features are integrated, and how are they configured?
MP2930GQK-LF-P integrates three thermal functions: VR_FAN triggers at TM = 1.65 V (≈85°C with typical NTC), VR_HOT at TM = 1.4 V (≈105°C), and internal thermal shutdown at TJ = 150°C. Configuration requires only an NTC thermistor from TM to GND and pull-up resistor to VCC-no external comparators needed.
