Product details
Overview
MP2152GQFU-Z 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 - ideal for battery-powered portable instruments and low-voltage I/O power rails.
For engineers reviewing the MP2152GQFU-Z datasheet, MP2152GQFU-Z pinout, MP2152GQFU-Z application, or MP2152GQFU-Z equivalent, key selection criteria include ultra-low IQ for standby efficiency, COT control for fast load transient response, integrated output discharge for safe power sequencing, and thermal/overvoltage protections in a space-constrained QFN footprint.
Technical Context
The MP2152GQFU-Z employs constant-on-time (COT) control with input voltage feed-forward, enabling 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 support up to 2A continuous output current with minimal external components.
Fault handling includes cycle-by-cycle current limiting (2.8A P-FET peak), hiccup-mode short-circuit protection, thermal shutdown at 160°C, and dual-stage overvoltage protection: dynamic VOUT regulation at 115% VFB and absolute VIN OVP at 6.1V. Output discharge is activated automatically during shutdown via an internal 200Ω resistor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 5.5V - supports single-cell Li-ion, USB, and logic-supply rails without pre-regulation. |
| Output Current | 2A continuous - delivers full rated current at ambient ≤85°C with proper PCB thermal design. |
| Quiescent Current | 25μA - enables >10-year battery life in always-on IoT sensors and wearables. |
| Switching Frequency | 1.1MHz - allows use of compact 1μH–2.2μH shielded inductors and reduces EMI filtering burden. |
| Feedback Accuracy | ±1% at 25°C (±1.5% over –40°C to +125°C) - ensures precise core voltage regulation for DSPs and FPGAs. |
| Internal MOSFET RDS(ON) | 75mΩ (HS) / 45mΩ (LS) - minimizes conduction loss and eliminates need for external power switches. |
| Soft-Start Time | 0.5ms - prevents inrush current and output overshoot during power-up sequencing. |
| Output Discharge | 200Ω internal path - actively discharges VOUT within milliseconds after EN deactivation for system safety. |
Pinout & Package
MP2152GQFU-Z is housed in a 6-pin, 1.2mm × 1.6mm, 0.4mm pitch UTQFN package with wettable flanks for automated optical inspection. Thermal pad on underside enhances heat dissipation to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Power Ground | Main return path for high-current switching loop; must be connected to large copper pour for thermal and EMI performance. |
| 2 SW | Switch Node | Drain of internal high-side MOSFET; connects directly to inductor; critical for minimizing switching loop area. |
| 3 VIN | Input Supply | 2.5V–5.5V unregulated input; requires local 10μF ceramic decoupling capacitor placed adjacent to pin. |
| 4 EN | Enable Control | Active-high logic input (1.2V threshold); internal 1MΩ pull-down enables default disable when floating. |
| 5 FB | Feedback Input | Senses output voltage via external resistor divider; 600mV reference enables adjustable VOUT from 0.6V. |
| 6 OUT | Output Sense & Power Rail | Connects to output capacitor and load; provides direct sensing point for stability and regulation accuracy. |
Key Features

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 |
|---|---|---|---|
| TPS62865RQYR | Higher IQ (12μA), smaller 1.2mm × 1.2mm DSBGA, but max 1.5A output and no output discharge. | Limited to lower-current applications where board space is more constrained than discharge requirement. | Select if ultra-low IQ and minimal footprint outweigh 0.5A current reduction and absence of discharge path. |
| RTQ2132BGQW | 2.5A rating, 15μA IQ, but larger 2mm × 2mm QFN and no integrated discharge resistor. | Suitable for higher-current designs needing margin, but requires external discharge circuit for sequencing. | Choose when >2A headroom is mandatory and external discharge FET + RC network is acceptable. |

FAQ
What is the minimum output voltage supported by MP2152GQFU-Z?
The MP2152GQFU-Z supports output voltages as low as 0.6V using an external resistor divider on the FB pin. This is enabled by its internal 600mV feedback reference voltage and ±1% accuracy, allowing precise regulation for modern low-voltage cores such as ARM Cortex-M4F or RISC-V SoCs.
Does MP2152GQFU-Z require an external power-good indicator?
No - the PG pin is only present on fixed-output variants (e.g., MP2152GQFU-33). The MP2152GQFU-Z is the adjustable version and does not include the PG function; it relies solely on FB monitoring and EN control for system sequencing.
How does the output discharge feature operate during shutdown?
When EN is pulled low, the MP2152GQFU-Z automatically activates an internal 200Ω discharge path between OUT and GND, discharging typical 22μF output capacitors in under 10ms. This prevents residual voltage from interfering with downstream logic states or causing latch-up in powered-off subsystems.
Can MP2152GQFU-Z operate with input voltage equal to output voltage?
Yes - it supports 100% duty cycle operation, allowing VIN = VOUT (e.g., 3.3V in → 3.3V out) without dropout. This is essential for LDO-replacement applications where minimal voltage headroom exists, such as powering 3.3V peripherals from a 3.6V Li-ion cell.
What thermal performance can be expected in the UTQFN package?
On a standard 2-layer PCB per EV2152-QFU-00A, the UTQFN package achieves θJA = 65°C/W. With proper thermal pad soldering and 2-in² copper pour, junction temperature rise remains below 40°C at 2A/3.3V output - well within the 125°C max operating limit.
Is the MP2152GQFU-Z compatible with ceramic output capacitors?
Yes - the COT control architecture is inherently stable with low-ESR ceramic capacitors. Recommended output capacitance is ≥22μF (X5R/X7R), and the device does not require ESR-based damping, simplifying layout and reducing bill-of-materials cost.
What protection features prevent damage during abnormal conditions?
The MP2152GQFU-Z integrates cycle-by-cycle current limiting (2.8A HS peak), hiccup-mode short-circuit protection, thermal shutdown at 160°C, VOUT overvoltage regulation (115% VFB), and absolute VIN OVP (6.1V), providing comprehensive fault coverage without external supervision circuitry.
