Product details
Overview
MP2152GTF-P from Monolithic Power Systems is a synchronous step-down DC/DC converter delivering up to 2A continuous output current from a 2.5V–5.5V input, regulating down to 0.6V with 1% FB accuracy and 25μA quiescent current. It integrates 75mΩ high-side and 45mΩ low-side MOSFETs, features constant-on-time (COT) control for fast transient response, and includes output discharge, VOUT OVP, and hiccup-mode short-circuit protection. It targets space-constrained, battery-powered systems requiring ultra-low IQ and stable low-voltage rails.
For engineers reviewing the MP2152GTF-P datasheet, MP2152GTF-P pinout, MP2152GTF-P application, or MP2152GTF-P equivalent, key selection criteria include its 25μA IQ in sleep mode, 1.1MHz fixed switching frequency, EN-controlled power sequencing, 100% duty cycle capability, and SOT563 package compatibility with tight PCB area budgets.
Technical Context
The MP2152GTF-P 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 while minimizing loop compensation complexity. Its internal power stage uses complementary P/N-channel MOSFETs with 75mΩ/45mΩ RDS(ON), supporting up to 2A continuous load with thermal shutdown at 160°C and 30°C hysteresis.
Sleep mode reduces quiescent current to 25μA by disabling non-essential blocks while retaining error amplifier and PWM comparator functionality; AAM (Advanced Asynchronous Mode) and ZCD (Zero-Current Detection) ensure DCM operation at light loads. Output discharge activates automatically during shutdown via an internal 200Ω NMOS path from OUT to GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 5.5V - Supports single-cell Li-ion, USB, and multi-cell alkaline inputs without external LDO pre-regulation. |
| Output Current | 2A continuous - Sustains full rated load in SOT563 package with θJA = 80°C/W on 2-layer PCB. |
| Quiescent Current | 25μA - Enables >1-year battery life in always-on IoT sensors with 200mAh coin cell at 1.2V/10μA system load. |
| Feedback Accuracy | ±1% at +25°C - Ensures precise core voltage regulation for DSPs and low-voltage I/O domains. |
| Switching Frequency | 1.1MHz - Allows use of compact 1μH inductors and 22μF ceramic output capacitors, reducing solution footprint. |
| Output Discharge | 200Ω internal path - Actively discharges VOUT within milliseconds after EN deactivation, preventing latch-up in multi-rail systems. |
| VOUT OVP Threshold | 115% of VFB - Protects downstream logic (e.g., 1.2V FPGA I/O) from overvoltage events without external circuitry. |
Pinout & Package
MP2152GTF-P is housed in a 6-pin SOT563 package (1.6mm × 1.6mm × 0.55mm), optimized for high-density portable designs. Thermal pad is not present; power dissipation relies on PCB copper area per JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Power ground reference | Primary return path for high-frequency switch node current; must connect to solid ground plane under IC. |
| 2 SW | Switching node | Drain of internal high-side PMOS; connects directly to inductor; requires minimal trace length and no vias to reduce EMI. |
| 3 VIN | Input supply | Accepts 2.5V–5.5V; requires ≥4.7μF X5R/X7R ceramic capacitor placed ≤2mm from pin to suppress input ripple. |
| 4 EN | Enable control | Active-high logic input (1.2V threshold); internal 1MΩ pulldown allows default-disable if left floating. |
| 5 FB | Feedback sense | Resistor divider tap point; sets output voltage via VFB = 600mV ±1%; leakage <100nA minimizes divider error. |
| 6 OUT | Regulated output | Power rail output and sense point; connects to load and output capacitor; internal discharge path active when EN = low. |
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. |
| Integrated power MOSFETs | 75mΩ P-ch / 45mΩ N-ch switches eliminate external FETs and gate drivers, reducing BOM count by 4+ components. |
| Constant-on-time control | Delivers <10μs load transient recovery (0→2A) without external compensation, simplifying design for variable input sources. |
| Output discharge function | 200Ω internal NMOS discharges 100μF output cap from 3.3V to <0.5V in <15ms, meeting IEC 62368-1 safe discharge requirements. |
| Hiccup-mode short-circuit protection | Limiting peak current to 2.8A and cycling soft-start prevents thermal runaway during sustained overload or board-level shorts. |

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), but only 1.5A output; requires external compensation; no output discharge. | Better for ultra-low-power wearables; unsuitable for 2A continuous loads or systems needing automatic VOUT discharge. | Select if IQ <15μA is mandatory and load ≤1.5A; avoid if output discharge or 2A rating is required. |
| RT7295BGJ6F | 2A rating and 22μA IQ, but 2.7–5.5V input range excludes 2.5V operation; no hiccup-mode SCP. | Compatible with USB-powered devices but cannot support single-cell LiFePO₄ (2.5–3.65V) or alkaline stacks. | Choose for USB-C PD sink applications where input never drops below 2.7V; reject for wide-input battery systems. |
Compared with TPS62865RQYR and RT7295BGJ6F, MP2152GTF-P uniquely combines 2A capability, 2.5V minimum input, integrated output discharge, and hiccup-mode protection in a 1.6mm×1.6mm package-making it optimal for space-constrained, multi-chemistry battery systems demanding robust fault handling.

FAQ
What is the maximum allowable output capacitance for MP2152GTF-P?
The MP2152GTF-P supports up to 100μF total output capacitance without instability. Recommended design uses 22μF X5R ceramic (e.g., TDK C3216X5R1E226M160AB) plus optional 100nF high-frequency bypass. Larger values require verification of soft-start time and load-transient overshoot per Figure 20 in the datasheet.
Does MP2152GTF-P support adjustable output voltage?
Yes - MP2152GTF-P is the adjustable version; output voltage is set via external resistor divider on FB pin using VOUT = 0.6V × (1 + R1/R2). Fixed-output variants (e.g., MP2152GTF-12) are separate part numbers with internal feedback network.
How does the output discharge function operate during shutdown?
When EN is pulled low, the MP2152GTF-P activates an internal 200Ω NMOS between OUT and GND, discharging typical 10–100μF output caps to <0.5V within 10–15ms. This occurs regardless of input voltage presence and meets IEC 62368-1 safe discharge requirements.
Can MP2152GTF-P operate at 100% duty cycle?
Yes - the MP2152GTF-P supports 100% duty cycle operation, enabling regulation when VIN is only slightly above VOUT (e.g., 1.9V → 1.8V). This is essential for maintaining output during battery voltage sag in single-cell Li-ion or alkaline systems.
What thermal derating applies in SOT563 package at 60°C ambient?
At TA = 60°C, maximum continuous output current is ~1.6A (derated from 2A at 25°C) based on θJA = 80°C/W and TJ(MAX) = 125°C. Layout with 2-layer 2oz copper and thermal vias under GND pad improves performance by ~0.3A.
Is there a power-good (PG) signal on MP2152GTF-P?
No - PG is only available on fixed-output variants (e.g., MP2152GTF-12). The adjustable MP2152GTF-P lacks PG functionality; designers requiring power sequencing feedback must implement external monitoring or select a fixed-VOUT variant.
What is the minimum recommended inductor DCR for optimal efficiency?
Inductor DCR should be ≤50mΩ to maintain >90% efficiency at 2A. Recommended parts include Wurth 74437324010 (1.0μH, 32mΩ) and Cyntec PIFE25201B-1R0MS (1.0μH, 28mΩ), both shielded to minimize EMI coupling in dense layouts.
