Product details
Overview
MP2152DGQFU-Z from Monolithic Power Systems is a synchronous step-down DC-DC converter with integrated 75mΩ high-side and 45mΩ low-side MOSFETs, delivering up to 2A continuous output current across a 2.5V–5.5V input range while regulating output down to 0.6V. It employs constant-on-time (COT) control for fast transient response and features fast output discharge, 1% FB accuracy, and 25μA quiescent current-enabling efficient power delivery in space-constrained SSD and portable instrumentation.
For engineers reviewing the MP2152DGQFU-Z datasheet, MP2152DGQFU-Z pinout, MP2152DGQFU-Z application, or MP2152DGQFU-Z equivalent, key selection considerations include its UTQFN-6 (1.2mm×1.6mm) package, 1.1MHz switching frequency, enable-controlled power sequencing, thermal shutdown at 160°C, and OVP/SCP protection with hiccup recovery-critical for battery-powered and low-voltage embedded systems.
Technical Context
The MP2152DGQFU-Z uses constant-on-time (COT) control with VIN feed-forward to maintain stable 1.1MHz switching frequency across input and output voltage variations. Its internal P-channel HS-FET and N-channel LS-FET are optimized for low RDS(ON), enabling high efficiency at light loads via AAM mode and deep sleep operation.
It integrates zero-current detection (ZCD), 100% duty-cycle capability, and dynamic output over-voltage regulation triggered at 115% of VFB, with fast discharge enabled by an internal 13Ω pull-down on the OUT pin when EN is deasserted.
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 external LDO pre-regulation. |
| Output Current | 2A continuous - sufficient for core logic, memory, and interface ICs in SSDs and portable instruments. |
| Feedback Accuracy | ±1% - ensures tight output regulation critical for low-voltage microcontrollers and sensors. |
| Quiescent Current | 25μA - enables multi-week standby in battery-powered devices without significant drain. |
| Switching Frequency | 1.1MHz - allows use of compact 1μH inductors and reduces EMI filtering requirements. |
| Output Discharge Resistance | 13Ω - actively discharges output capacitors within milliseconds after shutdown, preventing residual voltage hazards. |
| Thermal Shutdown Threshold | 160°C with 30°C hysteresis - protects die integrity during sustained overload or poor PCB thermal design. |
Pinout & Package
MP2152DGQFU-Z is housed in an ultra-compact UTQFN-6 package (1.2mm × 1.6mm, 0.5mm pitch), optimized for high-density PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Power ground reference | Primary return path for HS-FET, LS-FET, and control circuitry; must be connected to low-impedance ground plane. |
| 2 SW | Switching node | Drain of internal P-channel HS-FET; connects directly to inductor; carries high di/dt and requires short, wide trace routing. |
| 3 VIN | Input supply | Accepts 2.5V–5.5V unregulated input; requires local 22μF ceramic decoupling capacitor placed adjacent to pin. |
| 4 EN | Enable control | Active-high logic input (1.2V threshold); internal 1MΩ pulldown enables default-off behavior and supports power sequencing. |
| 5 FB | Feedback sense | Monitors resistor divider output; 600mV reference enables adjustable VOUT from 0.6V using standard 1% resistors. |
| 6 OUT | Output voltage sense | Direct connection to output rail; provides VOUT sensing for fast discharge MOSFET and OVP monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-On-Time (COT) Control | Enables <10μs load transient response without external compensation components. |
| Fast Output Discharge | 13Ω internal discharge path reduces VOUT to <100mV within 1ms after EN deactivation. |
| Advanced Asynchronous Modulation (AAM) | Extends light-load efficiency by entering discontinuous conduction mode below ~100mA. |
| Integrated Protection Suite | Includes cycle-by-cycle OCP, hiccup-mode SCP, 115% OVP, and thermal shutdown with hysteresis. |
| Ultra-Small UTQFN-6 Package | 1.2mm × 1.6mm footprint saves >40% board area versus SOT563 while improving thermal performance (θJA = 65°C/W). |

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 |
|---|---|---|---|
| TPS62864DLCR | Higher 3A rating, 2.5V–5.5V input, but larger DSBGA-12 package (1.6mm×1.6mm) and 30μA IQ. | Requires more PCB area and delivers higher current than needed for 2A SSD applications. | Choose when 3A headroom or I²C programmability is required; not optimal for size-constrained 2A designs. |
| RT7295BGJ6F | Same 2A/2.5V–5.5V spec, but uses fixed-frequency PWM (not COT), 40μA IQ, and no integrated output discharge. | Lacks fast transient response and active discharge-unsuitable for systems requiring rapid power cycling. | Select only if fixed-frequency EMI profile is mandatory; otherwise inferior for portable instrumentation. |
Compared with TPS62864DLCR and RT7295BGJ6F, MP2152DGQFU-Z offers the smallest footprint (1.2mm×1.6mm), lowest IQ (25μA), and unique fast output discharge-making it optimal for space- and battery-life-critical SSD and portable instrument designs where COT control enhances dynamic stability.

FAQ
What is the minimum output voltage supported by MP2152DGQFU-Z?
The MP2152DGQFU-Z supports an adjustable output voltage down to 0.6V, set by an external resistor divider on the FB pin referencing its internal 600mV feedback threshold. This enables direct powering of modern low-voltage cores such as ARM Cortex-M series MCUs and LPDDR memory interfaces.
Does MP2152DGQFU-Z require external compensation components?
No. The MP2152DGQFU-Z uses constant-on-time (COT) control architecture, eliminating the need for external loop compensation components like type-II or type-III networks. Stability is inherent across all operating conditions, simplifying layout and reducing BOM count.
How does the fast output discharge function operate?
When the EN pin is pulled low, the MP2152DGQFU-Z activates an internal 13Ω NMOS discharge path between the OUT and GND pins. This actively pulls down the output capacitor voltage to <100mV within 1ms, preventing residual voltage from interfering with downstream logic sequencing or causing latch-up.
What thermal performance can be expected in the UTQFN-6 package?
In a standard 2-layer PCB evaluation board (EVL2152D-QFU-00A), the MP2152DGQFU-Z exhibits θJA = 65°C/W and θJC = 30°C/W. At 2A load and 5V input, junction temperature rise remains below 85°C-well within the 125°C maximum operating limit-enabling reliable operation without forced airflow.
Is the MP2152DGQFU-Z RoHS-compliant and halogen-free?
Yes. MP2152DGQFU-Z is lead-free, halogen-free, and fully compliant with the EU RoHS directive. MPS confirms green status per its Quality Assurance documentation, and the device meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 rating for unlimited floor life at ≤30°C/60% RH.
Can MP2152DGQFU-Z operate with 100% duty cycle?
Yes. The MP2152DGQFU-Z supports 100% duty cycle operation, allowing regulation down to VOUT ≈ VIN − VSW_DROP. This enables stable output during input voltage sags-for example, maintaining 3.3V output as VIN drops from 4.2V to 3.6V in a Li-ion powered system.
What is the recommended inductor for typical 1.2V/2A operation?
MPS recommends the MPL-AL4020-1R0 (1μH, 10.1mΩ DCR) shielded metal-alloy inductor. It delivers optimal efficiency (>94% at 2A), minimal EMI, and fits the compact layout-validated in the MP2152D reference design EVL2152D-QFU-00A.
