Product details
Overview
MP3410DJ-LF-P from Monolithic Power Systems is a synchronous rectified step-up DC-DC converter with fixed 550kHz switching frequency, 1.3A typical switch current limit, internal soft-start and output-to-input disconnect capability. It operates from 1.8V to 6V input, delivers up to 6V output, and integrates both N-channel high-side and P-channel synchronous rectifier MOSFETs in a TSOT23-5 package-used in portable LCD bias supplies and camera flash drivers.
For engineers reviewing the MP3410DJ-LF-P datasheet, MP3410DJ-LF-P pinout, MP3410DJ-LF-P application, or MP3410DJ-LF-P equivalent, key selection criteria include its 1.19V feedback reference voltage, zero-current shutdown mode, thermal shutdown at 160°C, and compatibility with ceramic output capacitors as low as 4.7µF for compact 3.3V/400mA boost designs.
Technical Context
The MP3410DJ-LF-P employs fixed-frequency current-mode control with an internal 1.2V reference and error amplifier to regulate output via external resistive divider. Its architecture integrates dual MOSFETs (N-channel switch + P-channel synchronous rectifier) enabling >90% efficiency and eliminating external diode losses.
Startup behavior is governed by UVLO (1.65V typ), soft-start timer limiting error amplifier output, and EN pin logic-level control with VIN-dependent high-threshold (1.05V–2.15V). Output disconnect occurs when EN is low, isolating OUT from SW via P-MOSFET body diode reversal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 550kHz fixed - enables compact LC filter design with 4.7µH inductor and ≤10µF ceramic output capacitor. |
| Feedback Voltage | 1.19V ±0.04V - sets output voltage precision via external resistor divider (e.g., R1=220kΩ, R2=100kΩ for 3.8V). |
| Max Switch Current | 1.3A typical - supports ≥400mA output at 3.3V from 2.4V input with >90% efficiency. |
| Input Voltage Range | 1.8V to 6V - accommodates single-cell Li-ion (2.5–4.2V), NiMH (1.8–3.2V), or 3.3V rail boosting. |
| Thermal Shutdown | 160°C with 30°C hysteresis - protects die during overload or poor PCB thermal layout without latch-off. |
| Shutdown Supply Current | 0.5μA max - ensures battery-powered systems retain >10-year shelf life in storage mode. |
Pinout & Package
MP3410DJ-LF-P is housed in a 5-pin TSOT23-5 package (0.95mm pitch, 2.9mm × 1.6mm footprint), optimized for space-constrained portable applications. Thermal resistance θJA = 220°C/W on standard 4-layer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback Input | High-impedance node (50nA bias) sensing divided output voltage; connects to mid-point of R1/R2 divider for regulation. |
| 2 GND | Power Ground | Primary return path for switch current and IC bias; must tie directly to power plane under device for EMI control. |
| 3 OUT | Output Supply Rail | Connects to P-MOSFET source; provides regulated output and supplies internal bias circuitry when enabled. |
| 4 SW | Switch Node | Drain connection of both internal MOSFETs; requires low-inductance path to inductor and minimal loop area with CIN. |
| 5 EN | Enable Control | Logic-compatible input (0.4V low / ≥1.05V high); pulls down internally at 1MΩ; supports VIN-scaled threshold for robust sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| Internal Synchronous Rectification | Integrated P-channel MOSFET replaces Schottky diode, reducing conduction loss and enabling >90% efficiency at 400mA load. |
| Output-to-Input Disconnect | EN = low forces P-MOSFET body diode reverse-biased, fully isolating VOUT from VIN to prevent battery drain in standby. |
| Inrush Current Limiting | Soft-start timer caps error amplifier output slew rate, limiting peak input current to <1.5× steady-state during startup. |
| Zero-Current Shutdown Mode | Quiescent current drops to 0.5μA while maintaining EN pin responsiveness-critical for long-life coin-cell applications. |
| Internal Compensation | Single-pole compensation network embedded in error amplifier eliminates need for external capacitor, reducing BOM count by one part. |
Applications
| Digital Still Cameras | Handheld PDAs |
|---|---|

Use Value: Supports hot-plug detection via EN pin; output disconnect prevents backfeed into host 3.3V rail during cable removal. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar step-up converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61022DRVR | Higher 2A switch current, 1.2MHz switching, but requires external compensation and lacks output disconnect. | No built-in output isolation-requires external load switch for battery-sensitive applications. | Select when higher output current (>600mA) and faster transient response are prioritized over board area and shutdown leakage. |
| MAX8625ETA+ | Lower 1.1A switch limit, 1MHz frequency, integrated LDO post-regulator, no soft-start control. | Includes 3.3V LDO for noise-sensitive analog rails; less suitable for pure boost-only use cases. | Prefer when powering mixed-signal SoCs requiring clean auxiliary 3.3V from boosted main rail. |
Compared with TPS61022DRVR and MAX8625ETA+, MP3410DJ-LF-P offers optimal balance of ultra-low shutdown current (0.5μA), integrated output disconnect, and minimal external component count-making it ideal for space- and battery-life-constrained portable devices where 400–600mA boost capability suffices.

FAQ
What is the minimum input voltage required to start regulation?
The MP3410DJ-LF-P features undervoltage lockout (UVLO) with a typical startup threshold of 1.65V. Regulation begins once VIN exceeds this level and EN is asserted high; below 1.65V, the device remains disabled regardless of EN state.
Can the MP3410DJ-LF-P drive a 5V/500mA load from a 2.4V input?
Yes-under typical conditions (TA = 25°C, 4.7µH inductor, 10µF output capacitor), the MP3410DJ-LF-P delivers 500mA at 5V from 2.4V input with ~87% efficiency and <25mVpp ripple, provided thermal design maintains junction temperature below 125°C.
Is an external Schottky diode required for 5V output operation?
An external Schottky diode (e.g., 1N5817) is recommended across SW and OUT only when VOUT ≥ 4V to clamp SW node voltage during light-load discontinuous conduction mode and prevent gate oxide stress on the internal P-MOSFET.
How does the EN pin behave with varying input voltage?
The EN pin's high-threshold increases with VIN: 1.05V min at VIN = 1.8V, 1.65V at VIN = 3.3V, and 2.15V at VIN = 5V. This prevents false turn-on during brown-out and ensures reliable enable sequencing across battery discharge profiles.
What is the maximum allowable output capacitance?
No hard upper limit exists, but values beyond 22µF offer diminishing returns. Larger capacitors improve transient response and reduce ripple, yet increase soft-start time and inrush current-designs exceeding 22µF should verify startup stability with actual load profile.
Does the MP3410DJ-LF-P support adjustable switching frequency?
No-the MP3410DJ-LF-P uses a factory-trimmed 550kHz oscillator with ±25% tolerance (410–690kHz). Frequency cannot be adjusted externally; for variable-frequency operation, consider the MP3421 or MP3422 families.
How is thermal performance affected by PCB layout?
θJA degrades significantly without proper copper pour: 220°C/W assumes 1in² 2oz Cu on top layer connected to GND pin. Adding thermal vias to inner ground planes reduces θJA to ~150°C/W, enabling 600mA continuous operation at +60°C ambient.
