Product details
Overview
MP2192GC-P from Monolithic Power Systems is a synchronous step-down DC/DC converter IC delivering up to 2A continuous output current from a 2.5V–5.5V input, regulating output down to 0.6V with 1% FB accuracy and 25µA quiescent current. It integrates 75mΩ P-channel and 45mΩ N-channel MOSFETs, uses Constant-On-Time (COT) control for fast transient response, and targets space-constrained battery-powered systems such as SSDs and portable instruments.
For engineers reviewing the MP2192GC-P datasheet, MP2192GC-P pinout, MP2192GC-P application, or MP2192GC-P equivalent, key selection criteria include ultra-low IQ for standby efficiency, WLCSP-6 package footprint (0.85mm × 1.25mm), EN-controlled power sequencing, VOUT OVP with 117% threshold, and hiccup-mode short-circuit protection.
Technical Context
The MP2192GC-P employs Constant-On-Time (COT) control with input voltage feed-forward, maintaining ~1.1MHz switching frequency across 2.5V–5.5V VIN and 0.6V–5.5V VOUT ranges. Its internal high-side P-MOSFET (75mΩ) and low-side N-MOSFET (45mΩ) enable synchronous rectification without external diodes.
It features integrated soft-start (1.1ms), output discharge via 13Ω internal resistor, cycle-by-cycle current limiting (3.5A typical peak), thermal shutdown at 160°C, and feedback-based over-voltage protection triggering at 117% of VFB with 13% hysteresis.
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 rails without pre-regulation. |
| Output Current | 2A continuous - sufficient for core logic, memory, and I/O rails in portable SoCs. |
| Quiescent Current | 25µA - enables >10-year battery life in always-on sensor nodes and RTC backup supplies. |
| Feedback Accuracy | ±1% at 25°C - ensures tight output regulation critical for low-voltage FPGA and ASIC cores. |
| Switching Frequency | 1.1MHz - allows use of compact 1µH shielded inductors and reduces EMI filter size. |
| Package | WLCSP-6 (0.85mm × 1.25mm) - ultra-small footprint ideal for wearables and thin mobile modules. |
| OVP Threshold | 117% of VFB - protects downstream 1.2V/1.8V loads from catastrophic overvoltage during feedback fault. |
Pinout & Package
MP2192GC-P is housed in a 6-ball Wafer-Level Chip-Scale Package (WLCSP-6) measuring 0.85mm × 1.25mm with 0.4mm ball pitch. The package exposes no exposed pad; thermal path relies on solder joint conduction to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | GND | Power ground reference for all internal circuits; must connect to low-impedance PCB ground plane. |
| A2 | OUT | Output voltage sense node and power rail connection; ties directly to output capacitor anode. |
| B1 | SW | Switching node connecting internal high-side and low-side MOSFETs; requires direct inductor attachment. |
| B2 | EN | Active-high enable input with 1.2V logic threshold; internal 1MΩ pulldown enables default-disable behavior. |
| C1 | VIN | Main power input (2.5V–5.5V); requires local 22µF ceramic decoupling within 2mm of the ball. |
| C2 | FB | Resistor-divider feedback input; regulates output by comparing divided VOUT to 600mV internal reference. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 25µA enables >10-year shelf life in coin-cell–powered IoT edge sensors. |
| Integrated power MOSFETs | 75mΩ P-ch + 45mΩ N-ch switches eliminate external FETs and reduce BOM count by 4 components. |
| Output discharge function | 13Ω internal discharge path safely bleeds VOUT to GND within 10ms after EN deactivation. |
| Hiccup-mode short-circuit protection | Auto-retry recovery prevents thermal runaway during sustained overload or board-level shorts. |
| 100% duty-cycle operation | Enables dropout-free regulation when VIN approaches VOUT - critical for Li-ion end-of-discharge. |

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 × 0.8mm DSBGA-6, but lower 1.5A output current and no output discharge. | Better for ultra-low-power wearables where 1.5A suffices and discharge is unnecessary. | Select if minimum IQ and smallest footprint outweigh need for 2A and active discharge. |
| RTQ2134BGQW | Higher 3A rating, 30µA IQ, QFN-10 package (2mm × 2mm), includes I²C programmability and telemetry. | Suitable for industrial HMIs requiring remote monitoring and dynamic voltage scaling. | Choose when programmability, higher current headroom, or thermal performance (θJA = 60°C/W) are prioritized over size. |
Compared with TPS62865RQYR, MP2192GC-P delivers 33% more output current in nearly identical area but lacks I²C control; versus RTQ2134BGQW, it offers 40% smaller footprint and 17% lower IQ, at the cost of fixed-output configurability and telemetry.

FAQ
What is the minimum output voltage supported by MP2192GC-P?
The MP2192GC-P regulates output down to 0.6V using an external resistor divider on the FB pin. This 0.6V internal reference enables direct support of modern low-voltage processors and memory interfaces, including 0.8V–1.2V core rails when combined with precision resistors.
Does MP2192GC-P require an external bootstrap capacitor?
No. The MP2192GC-P uses a charge-pump circuit to drive the high-side P-channel MOSFET gate, eliminating the need for an external bootstrap capacitor. This simplifies layout and reduces component count compared to N-channel high-side buck controllers.
How does the output discharge function operate?
When EN is pulled low, the MP2192GC-P activates an internal 13Ω NMOS discharge path between OUT and GND. This discharges the output capacitor within ~10ms (dependent on COUT value), preventing residual voltage from interfering with system reset sequencing or causing latch-up in downstream logic.
Can MP2192GC-P operate with input voltage below 2.5V?
No. The absolute minimum input voltage is 2.5V per datasheet specifications. Below this, UVLO disables operation. The device enters shutdown at VIN < 2.3V (rising threshold) and remains off until VIN exceeds 2.45V due to 135mV hysteresis - preventing oscillation near the undervoltage boundary.
What is the thermal resistance (θJA) of the WLCSP-6 package?
Measured on a 4-layer JEDEC-standard PCB per JESD51-7, θJA for MP2192GC-P in WLCSP-6 is 141°C/W. This value reflects worst-case board conditions and is intended for relative comparison only; actual thermal performance depends on PCB copper area, vias, and airflow.
Is the MP2192GC-P RoHS and REACH compliant?
Yes. MP2192GC-P is lead-free, halogen-free, and fully compliant with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full compliance documentation is available on the MPS Quality Assurance portal.
What inductor value is recommended for 1.2V/2A operation?
MPS recommends the MPL-AL4020-1R0 (1.0µH, 10.1mΩ DCR) for 1.2V/2A operation. This inductor is optimized for the MP2192GC-P's 1.1MHz switching frequency and provides <20mV output ripple with 22µF output capacitance while maintaining >90% efficiency across load range.
