Product details

Overview

MP2152GTF-Z 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, employs constant-on-time (COT) control for fast transient response, and includes output discharge, OVP, and hiccup-mode short-circuit protection. It powers battery-powered portable instruments and low-voltage I/O rails in space-constrained designs.

For engineers reviewing the MP2152GTF-Z datasheet, MP2152GTF-Z pinout, MP2152GTF-Z application, or MP2152GTF-Z equivalent, key selection considerations include its SOT563 package footprint, 25μA IQ in sleep mode, 1.1MHz switching frequency, EN-controlled power sequencing, and support for adjustable output via external resistor divider - all critical for ultra-low-power, high-density embedded power systems.

Technical Context

The MP2152GTF-Z uses constant-on-time (COT) control with input voltage feed-forward to maintain stable 1.1MHz switching across 2.5V–5.5V input and 0.6V–5.5V output ranges, eliminating loop compensation components. Its internal power stage integrates complementary P/N-channel MOSFETs (75mΩ/45mΩ), enabling high efficiency at light loads via AAM and sleep-mode operation.

Fault handling includes cycle-by-cycle current limiting (2.8A high-side peak), thermal shutdown at 160°C with 30°C hysteresis, VOUT over-voltage protection (115% VFB threshold), and automatic output discharge when disabled. The EN pin supports precise power sequencing with 1.2V logic-high threshold and 150μs turn-on delay.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	2.5V to 5.5V - supports single-cell Li-ion, USB, and 3.3V/5V rail inputs without pre-regulation.
Output Current	Up to 2A continuous - sufficient for powering DSP cores, RF transceivers, or multi-rail SoC I/O domains.
Quiescent Current	25μA - enables >1-year battery life in always-on sensor nodes with 200mAh coin cells.
Feedback Accuracy	±1% at 25°C - ensures tight regulation of 1.2V/1.8V/3.3V rails critical for memory and interface compliance.
Switching Frequency	1.1MHz - allows use of compact 1μH inductors and 22μF ceramic output capacitors in <10mm² layout area.
MOSFET R_DS(on)	75mΩ (HS) / 45mΩ (LS) - minimizes conduction loss and thermal rise at full load in SOT563 package.
Soft-Start Time	0.5ms - prevents inrush current and output overshoot during cold boot of FPGA or microcontroller subsystems.

Pinout & Package

SOT563 (2.1mm × 1.6mm × 0.55mm) thermally enhanced package with exposed pad; 6-pin configuration optimized for minimal PCB area and efficient heat dissipation in portable applications.

Pin/Terminal	Circuit Role	Design Meaning
GND	Power ground reference	Primary return path for high-current switch node and feedback network; must be connected to solid ground plane under IC.
SW	Switching node	Drain of internal high-side P-MOSFET; connects directly to inductor; carries high di/dt ripple requiring short, wide trace routing.
VIN	Main power input	Supplies internal circuitry and power switches; requires local 10μF ceramic decoupling within 3mm of pin.
EN	Enable control	Active-high logic input (1.2V threshold); internal 1MΩ pull-down enables default disable and automatic output discharge on deassertion.
FB	Feedback sense	Resistor-divider tap point for output voltage regulation; 600mV reference enables 0.6V–5.5V programmable output with ±1% accuracy.
OUT	Output power rail	High-current output terminal; connects to load and output capacitor; not internally sensed - requires direct connection to regulated rail.

Key Features

Feature	Design Value
Output discharge on disable	Integrated 200Ω discharge FET actively bleeds output capacitor to prevent residual voltage hold-up in battery-backed systems.
Constant-on-time (COT) control	Eliminates external compensation network and delivers <10μs load transient recovery for processor core voltage steps.
100% duty cycle capability	Enables dropout operation down to V_OUT = V_IN – 0.1V, supporting LDO-like behavior during brown-out conditions.
V_OUT over-voltage protection	Dynamic regulation limits output to ≤115% V_FB using low-side FET sinking; prevents damage to downstream 1.2V/1.8V logic.
Thermal shutdown with hysteresis	160°C trip with 30°C hysteresis ensures reliable fault recovery without oscillation in enclosed enclosures.

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
TPS62840DLCR	Lower IQ (150nA), fixed 1.8V/3.3V options only; no adjustable version; 2.5V–6V input; 1.2A max output.	Limited to fixed-output, lower-current applications where nanoscale IQ dominates over flexibility.	Select when battery life >10 years is required and output voltage is fixed; avoid if adjustable VOUT or 2A load needed.
RT7295BGJ5	Higher IQ (35μA), 3A output, 2.5V–5.5V input, but no output discharge or COT control (uses PWM).	Better for higher-current, less sensitive systems where transient response is secondary to cost.	Choose for cost-sensitive industrial sensors needing >2A margin; skip if output discharge or sub-50μA IQ is mandatory.

Compared with TPS62840DLCR and RT7295BGJ5, the MP2152GTF-Z uniquely balances ultra-low 25μA IQ, full 2A capability, adjustable output, and integrated discharge - making it optimal for compact, battery-critical portable electronics where both runtime and design flexibility are non-negotiable.

FAQ

What is the maximum recommended PCB temperature rise for MP2152GTF-Z at 2A load?

The MP2152GTF-Z in SOT563 has a θ_JA of 80°C/W on a 2-layer demo board. At 2A output into 1.2V, typical power dissipation is ~220mW. This yields ~18°C junction-to-ambient rise above 25°C ambient, well below the 125°C max operating junction temperature. Thermal derating begins above 85°C ambient per the datasheet's output current vs. temperature curve.

Does MP2152GTF-Z support forced PWM mode, or is it strictly COT-based?

The MP2152GTF-Z operates exclusively in constant-on-time (COT) mode with no forced PWM option. Its control architecture relies on input voltage feed-forward and zero-current detection to automatically transition between CCM, DCM, and sleep modes - eliminating need for external mode-select pins or complex loop tuning.

Can the FB pin be used for remote sensing in high-precision applications?

No - the FB pin is designed solely for local feedback via resistor divider connected directly to the OUT pin. The MP2152GTF-Z lacks dedicated remote-sense inputs or Kelvin connections; for <0.5% total output error, PCB layout must minimize trace resistance between OUT and FB divider, and between GND and GND pin.

Is the output discharge feature active during EN-driven shutdown only, or also during VIN undervoltage lockout?

Output discharge activates only when EN is pulled low (or left floating). During VIN UVLO (input <2.3V), the device stops switching but does not engage the internal discharge FET - the output remains held by the output capacitor until VIN recovers or EN is explicitly asserted low.

What is the minimum output capacitance required for stable operation with MP2152GTF-Z?

The datasheet specifies 22μF ceramic output capacitance (X5R/X7R, 6.3V rating) as standard for stability across 0.1–2A loads. Lower values (≥10μF) may work with careful layout and reduced load step magnitude, but 22μF ensures robust phase margin and meets the 10mV p-p ripple spec at full load per typical application circuit.

How does the MP2152GTF-Z handle input voltage transients exceeding 6.5V absolute maximum rating?

The absolute maximum VIN is 6.5V. Transients beyond this - even sub-10ns spikes - risk permanent damage to the internal high-side MOSFET and control circuitry. A TVS diode (e.g., SMAJ5.0A) or RC snubber at the VIN pin is strongly recommended in automotive or industrial environments with load-dump or inductive kick risks.

Does the MP2152GTF-Z provide power-good indication, and if so, how is it implemented?

No - the MP2152GTF-Z (adjustable version) does not include a power-good (PG) pin. Only fixed-output variants (e.g., MP2152GTF-12) integrate an open-drain PG output. For the GTF-Z, system-level power monitoring must be implemented externally using a voltage supervisor IC or MCU ADC sampling the regulated output.
