Product details
Overview
MP2153GTF-25-P from Monolithic Power Systems is a fixed-output, synchronous step-down DC/DC converter delivering 2.5V at up to 3A from a 2.5V–5.5V input, featuring 25μA quiescent current, 1.1MHz switching frequency, integrated 65mΩ/35mΩ MOSFETs, and output discharge functionality in SOT563 package. It targets low-power, space-constrained systems such as SSD power rails and portable instrumentation.
For engineers reviewing the MP2153GTF-25-P datasheet, MP2153GTF-25-P pinout, MP2153GTF-25-P application, or MP2153GTF-25-P equivalent, key selection criteria include fixed 2.5V output accuracy (±1%), thermal shutdown at 160°C, 100% duty-cycle capability, VOUT OVP threshold at 115% of nominal, and EN-controlled sequencing with 150μs turn-on delay.
Technical Context
The MP2153GTF-25-P employs constant-on-time (COT) control with input voltage feed-forward, enabling stable 1.1MHz operation across its 2.5V–5.5V input range and ensuring fast transient response without external compensation. Its internal high-side P-channel and low-side N-channel MOSFETs (65mΩ/35mΩ) support continuous 3A output with minimal external components.
It integrates output discharge via an internal MOSFET (200Ω), enters hiccup-mode short-circuit protection when peak current exceeds 4A, and provides VOUT over-voltage protection triggered at 115% of 2.5V (2.875V) with 10% hysteresis-critical for safeguarding downstream 2.5V logic and memory interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5V ±1% (2.475–2.525V) - ensures compatibility with 2.5V I/O standards and LPDDR2/3 memory rails. |
| Max Output Current | 3A continuous - supports high-current 2.5V domains in SSD controllers and FPGA I/O banks. |
| Quiescent Current | 25μA - enables >10-year battery life in always-on sensor nodes powered from coin cells or energy harvesters. |
| Switching Frequency | 1.1MHz - allows use of compact 1μH inductors and reduces EMI filtering footprint in dense PCB layouts. |
| Input Voltage Range | 2.5V to 5.5V - accepts single-cell Li-ion (3.0–4.2V), USB 5V, or regulated 3.3V/5V system rails without pre-regulation. |
| Thermal Shutdown | 160°C with 30°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking in sealed enclosures. |
| VOUT OVP Threshold | 115% of 2.5V = 2.875V - protects 2.5V logic circuits from latch-up or oxide breakdown during feedback fault conditions. |
| EN Logic High | ≥1.2V - compatible with 1.8V and 3.3V GPIOs for precise power sequencing in multi-rail systems. |
Pinout & Package
SOT563 (1.6mm × 1.6mm) ultra-small surface-mount package with wettable flanks, rated for 1.5W power dissipation at +25°C ambient and θJA = 80°C/W on 2-layer PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Power ground reference | Primary return path for high-frequency switch node current; must be connected to solid ground plane under IC for EMI and thermal performance. |
| 2 SW | Switching node | Drain of internal high-side P-MOSFET; connects directly to inductor; carries high di/dt; requires minimized loop area to reduce radiated emissions. |
| 3 VIN | Input supply | Accepts 2.5–5.5V unregulated input; requires local 10μF ceramic decoupling placed within 2mm of pin to suppress input voltage spikes. |
| 4 EN | Enable control | Active-high logic input; internal 1MΩ pulldown allows default-disable; 150μs delay from EN rise to SW activity enables controlled power-up sequencing. |
| 5 FB | Feedback (not used) | Internally tied to fixed 2.5V reference; left unconnected in -25-P variant - no external resistor divider required. |
| 6 OUT | Output sense | Direct connection to output capacitor; senses VOUT for regulation and OVP; requires Kelvin connection for accurate load regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Output Discharge | Integrated 200Ω discharge MOSFET activates automatically on EN deassertion, safely discharging 2.5V rail within <10ms - eliminates need for external bleed resistors in battery-backed systems. |
| Constant-On-Time Control | 1.1MHz switching maintained across full input (2.5–5.5V) and load (0–3A) range without loop compensation - simplifies design and improves transient response to CPU burst loads. |
| VOUT Over-Voltage Protection | Dynamic regulation mode engages at 2.875V (115% of 2.5V), forcing low-side FET on until VOUT recovers - prevents damage to 2.5V I/O peripherals during feedback open-circuit faults. |
| Hiccup-Mode Short-Circuit Protection | Enters 150μs PG delay + soft-start recovery cycle upon >4A peak current detection - limits average power dissipation to <100mW during sustained shorts, avoiding thermal runaway. |
| 100% Duty Cycle Capability | Supports dropout operation down to VIN = VOUT (2.5V) - enables seamless operation during brown-out conditions in portable devices powered by aging batteries. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS6286518RTER | Fixed 1.8V output; 4A rating; 1.8MHz switching; 12μA IQ; requires external VDD capacitor. | Not pin-compatible; different output voltage; higher frequency demands tighter layout but reduces inductor size. | Select only if 1.8V (not 2.5V) is required and higher efficiency at light loads is prioritized over footprint. |
| Analog Devices ADP5302AUJZ-2.5-R7 | Fixed 2.5V output; 300mA max; 2.5μA IQ; 3MHz switching; integrated LDO post-regulator. | Insufficient current for SSD or printer loads; designed for ultra-low-power microcontrollers, not 3A applications. | Reject for any application requiring >500mA; suitable only for sensor nodes where 300mA and sub-3μA IQ outweigh current capability. |
Compared with TPS6286518RTER and ADP5302AUJZ-2.5-R7, the MP2153GTF-25-P uniquely balances 2.5V fixed output, 3A capability, 25μA IQ, and SOT563 size - making it the sole fit for space-limited 2.5V/3A systems where neither higher-frequency nor ultra-low-IQ alternatives meet both voltage and current requirements.

FAQ
What is the exact output voltage tolerance of MP2153GTF-25-P across temperature?
The MP2153GTF-25-P delivers 2.5V with ±1% initial accuracy at +25°C and ±0.5% additional variation from –40°C to +125°C, resulting in a total guaranteed range of 2.463V to 2.537V. This is confirmed by electrical characterization in the datasheet Table "OUT voltage (MP2153XX-25)" under TJ = –40°C to +125°C conditions.
Does MP2153GTF-25-P require external feedback resistors?
No. The MP2153GTF-25-P is a fixed-output variant: the FB pin is internally connected to the 2.5V reference and must be left unconnected. Unlike adjustable versions (e.g., MP2153GTF), no external R1/R2 divider is needed, reducing BOM count and layout complexity.
How does the output discharge function operate, and what is its resistance value?
When EN is pulled low, the MP2153GTF-25-P automatically activates an internal discharge MOSFET between OUT and GND with a typical on-resistance of 200Ω. At 2.5V, this provides ~12.5mA discharge current, fully discharging a 22μF output capacitor in under 10ms - verified in typical performance curves on page 7 of the datasheet.
What thermal derating applies at 60°C ambient temperature?
At TA = 60°C, the maximum continuous output current is derated to approximately 2.4A for the SOT563 package. This is derived from the "Output Current Derating vs. Ambient Temperature" graph (page 9), where the curve for VIN=5V/VOUT=2.5V intersects 60°C at ~2.4A, assuming standard 2-layer PCB layout per EV2153-TF-00A evaluation board.
Is the MP2153GTF-25-P RoHS and REACH compliant?
Yes. All MP2153 variants, including MP2153GTF-25-P, are lead-free, halogen-free, and fully compliant with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. MPS confirms green status on its official Quality Assurance webpage and in the "All MPS parts are lead-free, halogen-free…" statement on page 1 of the datasheet.
Can MP2153GTF-25-P operate with 100% duty cycle, and under what conditions?
Yes. The MP2153GTF-25-P supports 100% duty cycle when VIN ≤ VOUT + VDROP, enabling dropout operation down to VIN = 2.5V. This occurs when input voltage sags near the output level - critical for maintaining 2.5V rail stability during battery discharge in portable systems, as specified in the "Maximum duty cycle" row of the Electrical Characteristics table.
What is the minimum recommended output capacitance for stable operation?
The datasheet specifies 22μF ceramic output capacitance (C2 in Typical Application on page 1) as the baseline for stable 2.5V/3A operation. Using less than 15μF risks instability and excessive ripple; X5R/X7R dielectrics with ≥1206 case size are recommended to maintain effective capacitance under DC bias and temperature.
