Product details
Overview
MP2192CGC-Z from Monolithic Power Systems is a 2A synchronous step-down DC-DC converter with forced PWM mode, constant-on-time (COT) control, and integrated 75mΩ P-channel and 45mΩ N-channel MOSFETs. It operates from 2.5V to 5.5V input, delivers adjustable output down to 0.6V, and targets compact power rails in portable instrumentation and low-voltage I/O systems.
For engineers reviewing the MP2192CGC-Z datasheet, MP2192CGC-Z pinout, MP2192CGC-Z application, or MP2192CGC-Z equivalent, key selection criteria include its 1.1MHz switching frequency, 1% FB voltage accuracy, 100% duty-cycle capability, thermal shutdown at 160°C, and WLCSP-6 package compatibility with high-density PCB layouts.
Technical Context
The MP2192CGC-Z uses VIN feed-forward COT control to maintain stable 1.1MHz switching across 2.5V–5.5V input and 0.6V–5.5V output ranges, enabling fast transient response without external compensation. Its internal power stage integrates complementary P/N-channel MOSFETs with on-resistances of 75mΩ and 45mΩ, supporting up to 2A continuous output current with cycle-by-cycle current limiting.
Operation includes forced PWM mode for consistent ripple and EMI behavior, EN-controlled sequencing with 1.2V logic-high threshold, soft-start (1.2ms), output discharge via 13Ω internal resistor, and dual-stage over-voltage protection: dynamic FB-based regulation (117% VREF trigger) followed by absolute VIN OVP at 6.2V.
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 | 2A continuous - sustains full load under worst-case thermal conditions (TJ ≤ 125°C) on standard 2-layer PCB. |
| Feedback Accuracy | ±1% at 25°C - ensures tight output regulation (e.g., ±12mV at 1.2V) critical for DSP and FPGA core supplies. |
| Switching Frequency | 1.1MHz - enables use of small 1µH shielded inductors and reduces filter component size. |
| Quiescent Current | 450µA at VIN=5V - minimizes standby power loss in battery-powered devices during active operation. |
| Thermal Shutdown | 160°C with 30°C hysteresis - provides robust over-temperature recovery without latch-up. |
| Output Discharge | 13Ω internal resistor - actively discharges VOUT when disabled, preventing floating rail issues in power sequencing. |
Pinout & Package
MP2192CGC-Z is housed in a 6-ball WLCSP package (0.85mm × 1.25mm, 0.4mm pitch), optimized for ultra-compact portable designs. The bottom-side ball layout follows JEDEC MO-211 and requires controlled reflow per MSL Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | GND | Power ground reference; must be connected to low-impedance PCB ground plane for stable regulation and EMI control. |
| A2 | OUT | Output power rail and voltage sense node; connects directly to output capacitor and feedback divider top node. |
| B1 | SW | Switching node between internal P/N-MOSFETs; requires short, wide trace to inductor to minimize ringing and EMI. |
| B2 | EN | Enable control with 1.2V logic-high threshold; internal 1MΩ pulldown allows float-to-disable operation. |
| C1 | VIN | Input supply (2.5V–5.5V); requires local 22µF ceramic decoupling placed adjacent to this ball. |
| C2 | FB | Feedback input referenced to 0.6V internal reference; forms resistive divider with R1/R2 to set VOUT precisely. |
Key Features
| Feature | Design Value |
|---|---|
| Forced PWM Mode | Maintains fixed-frequency operation across all loads-eliminates audible noise and simplifies EMI filtering vs. PFM mode. |
| Constant-On-Time Control | Delivers <10µs load transient response with no external loop compensation required-reduces BOM count and design time. |
| Integrated Power MOSFETs | 75mΩ HS + 45mΩ LS switches enable >90% efficiency at 1.2V/2A (VIN=5V), reducing thermal footprint and external component count. |
| Output Over-Voltage Protection | Dual-stage OVP (FB-triggered dynamic regulation + VIN threshold) prevents damage to downstream 1.2V/1.8V ICs during fault conditions. |
| 100% Duty Cycle Capability | Allows dropout operation down to VOUT ≈ VIN − 0.1V-critical for maintaining rail integrity during brown-out events. |

FAQ
What is the minimum output voltage supported by MP2192CGC-Z?
The MP2192CGC-Z supports output voltages as low as 0.6V, set by the internal 0.6V feedback reference voltage and an external resistor divider. This enables direct generation of sub-1V rails for modern low-power processors and memory interfaces without additional components.
Does MP2192CGC-Z require external compensation components?
No. The MP2192CGC-Z uses constant-on-time (COT) control with VIN feed-forward, eliminating the need for external compensation networks. This simplifies design, reduces BOM count, and improves transient response without stability tuning.
How does the output discharge function operate during shutdown?
When EN is pulled low, the MP2192CGC-Z activates an internal 13Ω discharge path between OUT and GND, actively bleeding charge from the output capacitor. This prevents floating or slowly decaying output voltages that could cause latch-up in downstream logic.
What thermal performance can be expected on a standard 2-layer PCB?
On a 2-layer 64mm×48mm PCB (EVL2192C-C-00A demo board), the MP2192CGC-Z achieves θJA = 141°C/W. At 2A load and 5V input, case temperature rise is ~25°C-well within the 125°C max junction limit with adequate airflow or copper area.
Is the WLCSP-6 package compatible with standard SMT assembly processes?
Yes. The MP2192CGC-Z's WLCSP-6 (0.85mm×1.25mm, 0.4mm pitch) meets MSL Level 1 and is compatible with standard lead-free reflow profiles. Recommended land pattern and stencil design are provided in the datasheet Package Information section (page 18).
What protection features prevent damage during overload or short-circuit events?
The MP2192CGC-Z includes cycle-by-cycle current limiting (4A peak), thermal shutdown (160°C), output over-voltage protection (117% VREF trigger), and short-circuit protection with hiccup-mode recovery-automatically cycling startup until fault clears.
Can MP2192CGC-Z operate with input voltage equal to the desired output voltage?
Yes. The MP2192CGC-Z supports 100% duty-cycle operation, allowing it to maintain regulation when VIN drops to within ~100mV of VOUT-critical for sustaining system operation during battery brown-out conditions.
