Product details
Overview
MP2152GTF-25-Z from Monolithic Power Systems is a fixed-output 2.5V, 2A synchronous step-down DC/DC converter in SOT563 package, featuring 25μA quiescent current, 1.1MHz switching frequency, and integrated 75mΩ/45mΩ power MOSFETs. It delivers high efficiency across 2.5V–5.5V input range and supports output discharge, OVP, and hiccup-mode short-circuit protection - ideal for battery-powered portable instruments and low-voltage I/O power rails.
For engineers reviewing the MP2152GTF-25-Z datasheet, MP2152GTF-25-Z pinout, MP2152GTF-25-Z application, or MP2152GTF-25-Z equivalent, key selection criteria include its fixed 2.5V output accuracy (±0.5% at 25°C), EN-controlled power sequencing, thermal shutdown at 160°C, and compatibility with standard 1µH shielded inductors and 22µF ceramic output capacitors.
Technical Context
The MP2152GTF-25-Z employs constant-on-time (COT) control with input voltage feed-forward to maintain stable 1.1MHz switching across input (2.5–5.5V) and output (2.5V) conditions. Its internal architecture integrates high-side P-FET (75mΩ) and low-side N-FET (45mΩ), enabling up to 2A continuous output with 100% duty-cycle capability for low-dropout operation.
Fault management includes cycle-by-cycle current limiting (2.8A P-FET peak), VOUT over-voltage protection (115% VFB threshold with 10% hysteresis), and thermal shutdown with 30°C hysteresis. The device enters automatic output discharge mode when disabled via EN, using an internal 200Ω discharge path referenced to VOUT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5V ±0.5% at 25°C; ensures stable core/I/O rail for 2.5V logic systems without external feedback resistors. |
| Max Output Current | 2A continuous; supports high-current peripherals like USB PHYs or sensor arrays in space-constrained portable designs. |
| Quiescent Current | 25μA typical at 5V input; enables >1-year battery life in always-on IoT sensors with light-load sleep mode. |
| Switching Frequency | 1.1MHz nominal; allows use of compact 1µH inductors and reduces EMI filtering burden in dense PCB layouts. |
| Input Voltage Range | 2.5V to 5.5V; compatible with single-cell Li-ion (3.0–4.2V), 3.3V rails, and USB-powered systems. |
| Internal MOSFET RDS(ON) | 75mΩ (P-FET) / 45mΩ (N-FET); minimizes conduction loss and thermal rise at full load in SOT563 package. |
| Thermal Shutdown | 160°C junction temperature with 30°C hysteresis; prevents permanent damage during sustained overload or poor heatsinking. |
Pinout & Package
SOT563 (2.1mm × 1.6mm × 0.55mm) thermally enhanced package with exposed pad; optimized for low-profile, high-density portable applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Power ground reference | Primary return path for all internal circuits and power stage; must be connected to low-impedance PCB ground plane. |
| 2 SW | Switching node | Drain of internal high-side P-FET; connects directly to inductor; requires tight layout to minimize ringing and EMI. |
| 3 VIN | Input supply | Accepts 2.5–5.5V unregulated input; requires local 10µF ceramic decoupling capacitor placed within 2mm of pin. |
| 4 EN | Enable control | Active-high logic input (1.2V threshold); floating or grounded disables device and activates output discharge function. |
| 5 PG | Power good indicator | Open-drain output asserting high when VOUT is within ±10%/+15% of 2.5V; requires external 100–500kΩ pull-up to VIN. |
| 6 OUT | Output power rail | Regulated 2.5V output; connects to load and output capacitor; senses output voltage for regulation and protection loops. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ sleep mode | 25μA quiescent current enables >10-year shelf life in battery-backed real-time clocks and wearables. |
| Integrated output discharge | 200Ω internal discharge FET automatically bleeds VOUT to safe levels during shutdown - eliminates need for external circuitry. |
| Fixed 2.5V output with 1% FB accuracy | 600mV internal reference trimmed to ±0.5% ensures precise 2.5V rail for ADC references and memory interfaces. |
| Hiccup-mode short-circuit protection | Auto-retry soft-start recovery prevents thermal runaway during sustained shorts - protects downstream components and PCB traces. |
| VOUT over-voltage protection | 115% VFB detection triggers active low-side discharge until VOUT falls below 105% - avoids damage to 2.5V-tolerant ICs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS62231DRYR | Fixed 2.5V, 300mA max, 20μA IQ, 3MHz switching, WSON-6 package | Lower current rating limits use to ultra-low-power MCUs or sensors - not suitable for 2A loads. | Select only for sub-300mA applications where 3MHz allows smaller passives and tighter EMI control. |
| Analog Devices ADP2302ARDZ-2.5-R7 | Fixed 2.5V, 2A, 300μA IQ, 600kHz, SOIC-8 package | Higher 300μA IQ increases no-load power loss by 12×; larger SOIC-8 footprint incompatible with ultra-compact layouts. | Prefer only when SOIC-8 mechanical compatibility or higher thermal mass is required over SOT563 size constraints. |

FAQ
What is the exact output voltage tolerance of MP2152GTF-25-Z over temperature?
The MP2152GTF-25-Z delivers 2.5V output with ±0.5% initial accuracy at +25°C and ±0.75% total variation across –40°C to +125°C junction temperature, as confirmed by electrical characterization per datasheet Table 1 (VOUT = 2475–2537mV at full temp range).
Does MP2152GTF-25-Z require external feedback resistors?
No. MP2152GTF-25-Z is a fixed-output variant with internal resistor divider set to 2.5V; no external FB resistors are needed. The FB pin is unused and should be left unconnected or tied to GND per MPS layout guidelines.
How does the output discharge function operate during shutdown?
When EN is pulled low or floated, the MP2152GTF-25-Z activates an internal 200Ω discharge FET between OUT and GND, discharging the output capacitor to <100mV within ~1ms for a 22µF capacitor - eliminating risk of back-powering or latch-up in multi-rail systems.
Can MP2152GTF-25-Z operate with input voltage below 2.5V?
No. The absolute minimum operating input voltage is 2.5V per datasheet Recommended Operating Conditions. Under-voltage lockout (UVLO) disables the device below 2.3V rising threshold, and operation below 2.5V is not characterized or guaranteed.
Is the PG pin functional on MP2152GTF-25-Z?
Yes. As a fixed-output version, MP2152GTF-25-Z includes the PG (power good) open-drain output. It asserts high when VOUT is within –10% to +15% of 2.5V (i.e., 2.25V–2.875V) and pulls low outside that window, requiring a 100–500kΩ external pull-up resistor to VIN.
What is the maximum achievable efficiency at 2A load and 5V input?
At VIN = 5V, VOUT = 2.5V, and IOUT = 2A, the MP2152GTF-25-Z achieves up to 92% peak efficiency per Figure 1 (Efficiency vs. Output Current), measured with 1µH inductor and 22µF ceramic output capacitor on the EV2152-TF-00A evaluation board.
Does MP2152GTF-25-Z support forced PWM mode?
No. MP2152GTF-25-Z uses constant-on-time (COT) control with automatic transition between CCM, DCM, and sleep mode based on load. It does not offer a pin-selectable forced PWM mode - light-load efficiency is managed via AAM and ZCD circuitry instead.
