Product details

Overview

MP2192GC-Z from Monolithic Power Systems is a monolithic synchronous step-down DC/DC converter with integrated 75mΩ high-side and 45mΩ low-side MOSFETs, delivering up to 2A continuous output current from a 2.5V–5.5V input while regulating output down to 0.6V. It employs constant-on-time (COT) control for fast transient response in portable instrumentation and SSD power rails.

For engineers reviewing the MP2192GC-Z datasheet, MP2192GC-Z pinout, MP2192GC-Z application, or MP2192GC-Z equivalent, key selection criteria include its 25µA quiescent current, 1.1MHz switching frequency, 1% FB voltage accuracy, WLCSP-6 package footprint, and integrated output discharge and OVP/SCP protections.

Technical Context

The MP2192GC-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. Its sleep-mode operation reduces IQ to 25µA by disabling non-critical blocks while retaining EA and PWM comparator functionality.

It integrates dual MOSFETs (75mΩ PCH / 45mΩ NCH), supports 100% duty cycle for LDO-like dropout, and features programmable soft-start (1.1ms), EN-controlled sequencing, and hiccup-mode short-circuit protection triggered at 3.5A peak HS current limit.

OVP Threshold	117% of VFB - protects downstream 1.2V/1.8V/3.3V loads from overvoltage damage

Pinout & Package

MP2192GC-Z is housed in a 0.85mm × 1.25mm WLCSP-6 (Wafer-Level Chip-Scale Package) with bottom-side solder bumps. The ultra-compact footprint enables high-density PCB layouts in space-constrained applications such as SSD modules and handheld medical devices.

Pin/Terminal	Circuit Role	Design Meaning

A2 OUT	Output voltage sense and power rail	Direct connection point for output capacitor; also serves as feedback node for internal sensing
B1 SW	Switching node	Drain of internal high-side P-MOSFET; connects to inductor; carries high di/dt current
B2 EN	Enable control input	Active-high logic input (1.2V threshold); internal 1MΩ pull-down enables default disable
C1 VIN	Input supply	Unregulated 2.5V–5.5V source; requires local 22µF ceramic decoupling capacitor
C2 FB	Feedback input	Resistor-divider tap point; sets output voltage via VFB = 600mV ±1%; high-impedance (50–100nA)

Key Features

Feature	Design Value
Ultra-low quiescent current	25µA IQ enables multi-year battery operation in always-on IoT endpoints
Integrated output discharge	13Ω internal discharge FET clears residual output charge during shutdown, preventing backfeed
Constant-on-time (COT) control	Eliminates external compensation; achieves <10µs load transient recovery with minimal output capacitance
VIN OVP protection	6.2V absolute input overvoltage lockout prevents damage from accidental 12V/24V misconnection

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
TPS6286418RTER	Lower 1.8V min input; 1.8V fixed output; 17µA IQ; 2.5A rating	Fixed-output variant only; no adjustable FB; lacks output discharge	Select when fixed 1.8V output and lowest possible IQ are required, and output discharge is unnecessary
RTQ2134BGQW	Higher 3A rating; 30µA IQ; 2.7V–5.5V input; 0.6V–5.5V adjustable output	Larger QFN-10 package (2mm×2mm); higher thermal resistance (θJA = 120°C/W)	Select when >2A peak current or enhanced thermal margin is needed, accepting larger footprint

Compared with TPS6286418RTER and RTQ2134BGQW, MP2192GC-Z uniquely balances ultra-small WLCSP-6 size, 25µA IQ, adjustable 0.6V output, and integrated output discharge-making it optimal for space- and battery-limited SSD and portable instrument designs where flexibility and footprint are critical.

FAQ

What is the minimum recommended output capacitance for stable operation?

The MP2192GC-Z is optimized for use with ≥22µF X5R/X7R ceramic output capacitors. Lower values may cause instability or excessive ripple due to reduced phase margin in COT control. For 1.2V/2A operation, two parallel 10µF/0603 capacitors meet ESR and capacitance requirements while fitting the WLCSP-6 layout constraints.

Does MP2192GC-Z support forced PWM mode or only auto-frequency modulation?

The MP2192GC-Z operates exclusively in automatic mode-using COT control with Advanced Asynchronous Modulation (AAM) at light loads and natural CCM/DCM transitions. It does not support forced PWM or external frequency synchronization; frequency varies slightly with input/output voltage per t_ON = 0.91µs × V_OUT/V_IN.

How does the output discharge function behave during EN deactivation?

When EN is pulled low, the MP2192GC-Z automatically activates an internal 13Ω discharge FET between OUT and GND. This discharges the output capacitor within ~10ms (dependent on C_OUT value), preventing back-powering of upstream circuits and ensuring clean system reset sequencing.

Can MP2192GC-Z operate with input voltage below 2.5V?

No. The absolute minimum operating input voltage is 2.5V, enforced by a 2.45V UVLO rising threshold with 135mV hysteresis. Operation below 2.3V causes automatic shutdown; the device will not regulate or switch below this threshold, even with 100% duty cycle enabled.

What is the maximum achievable output voltage with standard external resistors?

While the FB reference is 600mV, the maximum practical output voltage is limited by internal voltage ratings and stability. With R1 = 200kΩ and R2 = 44.2kΩ, the MP2192GC-Z reliably delivers 3.3V. Higher outputs (e.g., 5V) require careful layout and capacitor selection but are electrically feasible per the resistor divider equation V_OUT = 0.6V × (1 + R1/R2).

Is the WLCSP-6 package compatible with standard reflow profiles?

Yes. The MP2192GC-Z WLCSP-6 package is qualified for JEDEC J-STD-020D MS Level 1 moisture sensitivity and supports standard lead-free reflow profiles (peak 260°C, 20–40s above 217°C). Board design must follow MPS's recommended pad layout and stencil aperture guidelines to ensure reliable solder joint formation.

How does thermal shutdown interact with continuous 2A load at 5.5V input?

At 5.5V input and 2A load, junction temperature rise depends on PCB copper area. On a 2-layer board with 141°C/W θ_JA, power dissipation (~0.3W) raises T_J by ~42°C above ambient. Shutdown triggers only if ambient exceeds ~83°C (125°C – 42°C), making it robust for typical industrial environments with adequate heatsinking.
