Product details
Overview
MP2152GQFU-P from Monolithic Power Systems is a 2A synchronous step-down DC/DC converter in a 1.2mm × 1.6mm UTQFN package, featuring 25μA quiescent current, 1.1MHz fixed switching frequency, and output discharge capability. It operates from 2.5V–5.5V input, regulates down to 0.6V, and integrates 75mΩ/45mΩ P/N-channel MOSFETs for high-efficiency power conversion in space-constrained portable electronics.
For engineers reviewing the MP2152GQFU-P datasheet, MP2152GQFU-P pinout, MP2152GQFU-P application, or MP2152GQFU-P equivalent, key selection criteria include ultra-low IQ for battery longevity, COT control for fast load transient response, integrated output discharge for safe power sequencing, and thermal shutdown with 160°C trip point in compact UTQFN packaging.
Technical Context
The MP2152GQFU-P employs constant-on-time (COT) control with input voltage feed-forward, delivering stable 1.1MHz operation across 2.5V–5.5V input and 0.6V–3.3V output ranges. Its internal 75mΩ high-side and 45mΩ low-side MOSFETs enable up to 2A continuous output current with minimal external components.
Fault protection includes cycle-by-cycle current limiting (2.8A P-FET peak), hiccup-mode short-circuit protection, VOUT over-voltage protection (115% VFB threshold), and thermal shutdown at 160°C with 30°C hysteresis - all implemented without external sensing circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 5.5V - supports single-cell Li-ion, USB, and regulated 3.3V/5V rails without pre-regulation. |
| Output Current | 2A continuous - sufficient for powering ARM Cortex-M cores, FPGAs, and RF transceivers in portable devices. |
| Quiescent Current | 25μA - enables >1-year battery life in always-on IoT sensors with 200mAh coin cells. |
| Switching Frequency | 1.1MHz - allows use of small 1μH inductors and 22μF ceramic output capacitors for ultra-compact layouts. |
| Feedback Accuracy | ±1% at 25°C - ensures tight regulation for sensitive analog circuits and memory I/O supplies. |
| Internal MOSFET RDS(on) | 75mΩ (P-FET) / 45mΩ (N-FET) - reduces conduction loss and thermal rise in 1.2mm×1.6mm UTQFN footprint. |
| Soft-Start Time | 0.5ms - prevents inrush current and overshoot during power-up of downstream logic and ADCs. |
| Output Discharge | Integrated 200Ω discharge path - eliminates hold-up voltage on VOUT after EN deactivation for safe system reset. |
Pinout & Package
MP2152GQFU-P is housed in a 6-pin, 1.2mm × 1.6mm, 0.4mm pitch UTQFN package with wettable flanks for automated optical inspection. Thermal pad exposed on bottom enhances PCB heat dissipation (θJA = 65°C/W on 2-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Power ground reference | Primary return path for high-current switching loop; must be connected to solid ground plane under IC. |
| SW | Switching node | Drain of internal high-side P-MOSFET; connects directly to inductor; critical for EMI and efficiency. |
| VIN | Main power input | Supplies internal bias and power stage; requires local 4.7μF–10μF X5R/X7R ceramic decoupling capacitor. |
| EN | Enable control | Active-high logic input (1.2V threshold); internal 1MΩ pull-down enables default-off behavior. |
| FB | Feedback input | Senses output voltage via external resistor divider; 600mV reference enables adjustable VOUT from 0.6V. |
| OUT | Output sense/power rail | Direct connection to regulated output; used for remote sensing and load regulation in precision applications. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 25μA enables >10-year shelf life in battery-backed real-time clocks and energy-harvesting nodes. |
| Constant-on-time (COT) control | Delivers <10μs load transient recovery without external compensation components. |
| Integrated output discharge | 200Ω internal MOSFET discharges VOUT within milliseconds after shutdown - eliminates need for external discharge circuitry. |
| 100% duty-cycle operation | Supports dropout operation down to VOUT ≈ VIN − 0.1V, ideal for LDO replacement in low-VIN scenarios. |
| VOUT over-voltage protection | Dynamic regulation at 115% VFB + hiccup recovery prevents damage to downstream 1.2V/1.8V logic during feedback fault. |
| Thermal shutdown with hysteresis | 160°C trip / 130°C release ensures robust operation under sustained 2A loads in sealed enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS62840YKAR | Lower IQ (300nA), but only 1A output; 2.7V–6V input; no output discharge; 1.8MHz switching. | Better for multi-year coin-cell applications, but insufficient for 2A loads like motor drivers or displays. | Select when ultra-deep sleep dominates design, and peak current ≤1A. |
| Analog Devices ADP5061ACBZ-1-R7 | 2A output, 2.3V–5.5V input, 25μA IQ, but SOT-23-6 package (larger than UTQFN); no output discharge. | Compatible pinout for legacy designs, but lacks integrated discharge and has higher θJA (130°C/W). | Choose for drop-in replacement where board rework is prohibited and discharge is handled externally. |
Compared with TPS62840YKAR and ADP5061ACBZ-1-R7, MP2152GQFU-P uniquely balances 2A capability, 25μA IQ, integrated output discharge, and 1.2mm×1.6mm UTQFN size - making it optimal for next-gen portable devices requiring both high peak current and multi-week battery life.

FAQ
What is the maximum recommended output capacitance for MP2152GQFU-P?
The MP2152GQFU-P is optimized for 22μF ceramic output capacitors (X5R/X7R, 6.3V rating). Larger values (up to 100μF) are acceptable but may increase soft-start time and reduce phase margin; stability must be verified with load-step testing per Figure 11 in the datasheet.
Does MP2152GQFU-P support forced PWM mode?
No - MP2152GQFU-P uses automatic advanced asynchronous mode (AAM) for light-load efficiency and cannot be forced into continuous PWM. It transitions seamlessly between CCM, DCM, and sleep mode based on load and FB ripple, eliminating audible noise and maximizing light-load efficiency.
Can MP2152GQFU-P operate with an input voltage below 2.5V?
No - the absolute minimum operating input is 2.5V. Under-voltage lockout (UVLO) disables the device below 2.3V (typical), and operation below 2.5V is not characterized or guaranteed. For sub-2.5V inputs, consider the MP2161 (1.8V–6V range) or discrete LDO solutions.
Is the PG pin available on MP2152GQFU-P?
No - the power-good (PG) pin is only present on fixed-output variants (e.g., MP2152GQFU-33). MP2152GQFU-P is the adjustable version and uses the FB pin for regulation; PG functionality is omitted to retain the 6-pin UTQFN footprint and reduce cost.
How does the output discharge function behave during EN deactivation?
When EN is pulled low, MP2152GQFU-P immediately disables switching and activates its internal 200Ω discharge MOSFET between OUT and GND. This discharges typical 22μF output capacitors to <100mV within ~1.5ms, ensuring safe, controlled power-down without external components.
What PCB layout practices maximize thermal performance in the UTQFN package?
Maximize thermal performance by connecting the exposed thermal pad to a solid internal or bottom-layer copper pour (≥200mm²) using ≥4 thermal vias (0.3mm diameter, filled or capped). Avoid splitting the GND plane under the IC; keep high-current SW and VIN traces short and wide to minimize inductance and EMI.
Does MP2152GQFU-P require an external bootstrap capacitor?
No - MP2152GQFU-P uses an internal charge pump to drive the high-side P-MOSFET gate, eliminating the need for an external bootstrap capacitor. This simplifies layout, reduces BOM count, and improves reliability in high-density portable designs.
