Product details
Overview
MP5410EQ-LF-Z from Monolithic Power Systems is a current-mode boost converter with integrated 0.65Ω N-Channel MOSFET, four SPDT analog switches, and fixed 10V output capability. It starts up from 1.8V input, delivers >80% efficiency at light loads, and features <1µA shutdown current-designed for low-power bias supply in battery-powered displays and 3D glass drivers.
For engineers reviewing the MP5410EQ-LF-Z datasheet, MP5410EQ-LF-Z pinout, MP5410EQ-LF-Z application, or MP5410EQ-LF-Z equivalent, key selection criteria include its dual-role as both high-efficiency step-up regulator and quad SPDT switch controller, low-startup-voltage operation, integrated Schottky diode, and QFN16 (3×3mm) thermal performance with exposed pad grounding.
Technical Context
The MP5410EQ-LF-Z implements variable-frequency, constant-peak-current control with internal compensation-eliminating external loop components. Its architecture combines a step-up converter (VIN 1.8–5.5V → VOUT up to 10V) and four independently controllable SPDT switches, each with ≤50Ω on-resistance and matched channel resistance (ΔR ≤10Ω).
It integrates input UVLO (1.58V threshold, 100mV hysteresis), over-temperature shutdown (150°C), soft-start with two-stage inrush limiting, and bidirectional disconnect switch between IN and L pins-enabling full load isolation during shutdown while maintaining <1µA quiescent draw.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.8V to 5.5V - supports single-cell Li+ or dual-cell NiCd/NiMH batteries without external LDO pre-regulation. |
| Startup Voltage | 1.8V - enables reliable power-up from deeply discharged alkaline or NiMH cells. |
| Output Voltage | Fixed 10V (±3%) or adjustable via FB divider - meets bias requirements for LCD gate drivers and 3D glass actuators. |
| Switch On-Resistance | 25Ω typical per SPDT channel - ensures minimal voltage drop across A/B/C/D outputs under 2mA load. |
| Shutdown Current | <1µA - preserves battery life in always-on portable devices during standby. |
| Thermal Protection | 150°C junction shutdown with automatic recovery - prevents latch-up during transient overload or poor PCB heatsinking. |
| Package | QFN16 (3×3mm, 0.5mm pitch) with exposed thermal pad - enables compact layout and 2.08W continuous dissipation at +25°C ambient. |
Pinout & Package
MP5410EQ-LF-Z uses a thermally enhanced 16-pin QFN package (3×3mm, 0.5mm pitch) with exposed pad soldered to PCB ground plane for optimal thermal performance and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 L | Inductor Output / Disconnect Switch Node | Connects to inductor; provides isolated output path when EN=LOW - enables full system power gating. |
| 2 EN | Enable Control Input | Logic HIGH (≥1.4V) activates converter and switches; LOW disables all functions and draws <1µA. |
| 3 S1, 4 S0, 9 S3, 10 S2 | SPDT Channel Control Inputs | Digital logic inputs selecting GND or OUT connection for B, A, D, C outputs respectively - no pull-up/down required. |
| 5 A, 6 B, 7 C, 8 D | SPDT Analog Switch Outputs | Low-leakage (nA), rail-to-rail capable outputs - suitable for biasing display electrodes or sensor signal routing. |
| 11 FB | Feedback Regulation Input | Floating = fixed 10V output; connected to resistor divider = programmable VOUT - sets regulation point at 1.23V reference. |
| 12 ISET | Peak Current Programming | Resistor to GND sets SW current limit (180mA typ. at 300kΩ) - adjusts switching frequency and inductor stress. |
| 13 GND | Ground Reference | Primary return path for power and signal; exposed pad must be connected to solid GND plane. |
| 14 IN | Main Input Supply | Powers internal circuitry and disconnect switch - requires local 4.7–10µF ceramic bypass capacitor. |
| 15 SW | Internal MOSFET Drain Node | High-frequency switching node - must connect directly to inductor with minimal trace length to reduce EMI. |
| 16 OUT | Boost Converter Output | 10V regulated output - supplies SPDT switches and external loads; requires low-ESR ceramic output capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power MOSFET + Schottky Diode | Eliminates 2 external components - reduces board area by ≥30% vs. discrete boost solutions. |
| Four Independent SPDT Switches | Enables dynamic reconfiguration of bias paths (e.g., polarity reversal in 3D glass drivers) without external analog switches. |
| Variable-Frequency Constant-Peak-Current Control | Maintains stable regulation across 1.8–5.5V input while minimizing output capacitor size and EMI. |
| Input Disconnection Architecture | PMOS+N-MOS parallel switch isolates battery from all loads - critical for zero-current standby in medical wearables. |
| Two-Stage Soft-Start with Inrush Limiting | Prevents input voltage sag during startup - avoids brownout in shared battery rails powering MCU and display simultaneously. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter with integrated analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61099YFFR | Single-output boost only; no integrated SPDT switches - requires external analog switches for multiplexing. | Lacks quad SPDT functionality; suitable only for pure voltage boosting without signal routing. | Select when SPDT switching is handled elsewhere and higher peak efficiency (>90%) at medium loads is prioritized. |
| MAX17222ETA+ | Includes enable-controlled load disconnect but no analog switches; lower max output (5.5V) and no ISET programming. | Cannot replace MP5410EQ-LF-Z in 10V bias or electrode polarity reversal use cases. | Choose for simpler 3.3V/5V boost needs where board space allows separate switch ICs and thermal budget is tighter. |
Compared with TPS61099YFFR and MAX17222ETA+, MP5410EQ-LF-Z uniquely integrates both high-efficiency 10V boost and four SPDT switches in one QFN16 package - eliminating interconnect parasitics, reducing component count, and enabling synchronized bias control unattainable with discrete solutions.

FAQ
What is the minimum input voltage required for MP5410EQ-LF-Z to start switching?
The MP5410EQ-LF-Z guarantees startup at 1.8V input with no load, verified across temperature and process corners. Below this threshold, the under-voltage lockout (UVLO) holds the device in shutdown regardless of EN state. Startup behavior is independent of output capacitor size or feedback configuration.
Can the MP5410EQ-LF-Z generate output voltages other than 10V?
Yes - floating the FB pin yields a fixed ~10V output, but connecting an external resistive divider (e.g., R1=178kΩ, R2=24.9kΩ) allows precise adjustment from VIN to 10V. The internal 1.23V reference and FB input bias current (1µA) enable stable regulation down to 2mA load with standard 1% resistors.
How does the MP5410EQ-LF-Z achieve load disconnection during shutdown?
It uses a dual-MOSFET disconnect switch between IN and L pins: a PMOS turns on first at startup, then a lower-RDS(ON) NMOS takes over once VOUT reaches threshold. During shutdown (EN=LOW), both transistors turn OFF, breaking the DC path from battery to all outputs - measured leakage is <100nA at 5.5V IN.
What is the maximum current each SPDT switch can handle continuously?
Each SPDT channel (A/B/C/D) is rated for 2mA continuous DC current at 10V output, with on-resistance ≤50Ω and matching ≤10Ω between channels. Transient current spikes up to 10mA are permissible for <100ns, validated in typical 3D glass drive waveforms with 100kHz switching.
Is the exposed thermal pad on the QFN16 package electrically connected internally?
Yes - the exposed pad is internally tied to GND and must be soldered to a dedicated PCB ground plane. Thermal resistance θJC is 12°C/W when properly connected, enabling 2.08W power dissipation at +25°C ambient. Leaving it unconnected degrades thermal performance by >40% and risks thermal shutdown.
Does MP5410EQ-LF-Z require external compensation components for stability?
No - it uses internal compensation optimized for ceramic output capacitors (≤10µF) and inductors (10µH typical). The current-mode architecture with fixed compensation eliminates need for external RC networks, simplifying design and improving immunity to component tolerance drift across temperature.
How does the ISET pin affect switching frequency and efficiency?
ISET sets peak inductor current: lower resistance increases current limit, lowering switching frequency and increasing inductor RMS current; higher resistance reduces frequency but raises conduction loss. At 300kΩ, typical frequency is 1.2MHz with 10µH inductor - balancing efficiency (>85% at 10mA) and EMI.
