Product details
Overview
MP2410GJ-P from Monolithic Power Systems is a 24V, 2A, synchronous step-down LED driver IC with integrated high-side MOSFET (100mΩ) and low-side synchronous rectifier (80mΩ), operating at fixed 1MHz switching frequency and supporting deep analog dimming via EN/DIM pin. It delivers stable current to white LED strings in handheld flashlights and infrared illumination systems.
For engineers reviewing the MP2410GJ-P datasheet, MP2410GJ-P pinout, MP2410GJ-P application, or MP2410GJ-P equivalent, key selection criteria include its 4.2–24V input range, 100mV feedback reference, NTC-based thermal foldback, inherent open-LED protection, and TSOT23-6 package compatibility with space-constrained portable designs.
Technical Context
The MP2410GJ-P implements peak-current-mode control with a 1MHz internal oscillator and 94% maximum duty cycle, enabling fast transient response and simplified loop compensation. Its error amplifier compares FB voltage against a precision 100mV reference to regulate LED current via COMP voltage modulation of high-side switch conduction time.
It integrates dual overcurrent protection: cycle-by-cycle limiting on both high-side (3.5–6.6A threshold) and low-side paths, plus dedicated short-circuit detection (IOCP = 3.6–7A) triggering 2.4ms hiccup-mode restart. Thermal shutdown activates at 150°C with 60°C hysteresis, while NTC pin enables ambient temperature–dependent current scaling using external thermistor networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.2V to 24V - supports wide industrial and battery-powered inputs including 12V/24V rails and multi-cell Li-ion stacks. |
| Max Output Current | 2A continuous - sufficient for driving high-brightness LED arrays in flashlight and IR illuminator applications. |
| Switching Frequency | Fixed 1MHz - enables use of compact 4.7µH inductors and reduces EMI filtering requirements. |
| Feedback Reference | 100mV ±7mV - low-voltage reference minimizes sense resistor power loss and improves dimming resolution. |
| Internal MOSFET RDS(on) | High-side: 100mΩ typ @ 5V; Low-side: 80mΩ typ @ 5V - eliminates need for external power switches and reduces BOM count. |
| Analog Dimming Range | VEN/DIM = 0.7V to 1.44V - maps linearly to full-scale LED current, enabling smooth brightness control without PWM artifacts. |
| Thermal Protection | NTC pin with 0.82V low-threshold and 1.25V high-threshold - allows programmable thermal foldback using standard 10kΩ NTC thermistors. |
Pinout & Package
MP2410GJ-P is housed in a TSOT23-6 package with exposed pad for thermal enhancement. Pin 1 is marked by a dot; pin numbering follows standard TSOT23 orientation (counterclockwise from dot).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Power and signal reference ground | Primary return path for LED current, SW node, and internal bias circuits; requires low-impedance PCB connection to minimize noise coupling. |
| 2 SW | Switch node | Drives external inductor; connects internally to source of high-side MOSFET and drain of low-side rectifier; critical for EMI layout. |
| 3 VIN | Main power input | Accepts 4.2–24V unregulated supply; must be decoupled with ≥10µF ceramic capacitor placed adjacent to pin. |
| 4 FB | Current-sense feedback | Monitors voltage across external sense resistor; internal 100mV reference sets LED current per ILED = 0.1V / RSENSE. |
| 5 EN/DIM | Enable and analog dimming input | DC voltage-controlled on/off and brightness; 0.59V turn-on threshold; 0.7–1.44V linear dimming range; 22ms shutdown delay. |
| 6 BST | Bootstrap supply | Connects external 0.1µF ceramic capacitor between BST and SW to generate floating gate drive for high-side MOSFET. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated 80mΩ low-side switch replaces external Schottky diode, improving efficiency up to 97% and eliminating reverse recovery losses. |
| Inherent open-LED protection | No external circuitry needed - device clamps at max duty cycle when FB floats, preventing overvoltage stress on LEDs and components. |
| NTC-based thermal foldback | Dedicated NTC pin with internal current source enables precise ambient temperature–dependent current reduction before thermal shutdown occurs. |
| Auto-restart hiccup mode | On SCP or overcurrent fault, disables switching for 2.4ms then soft-starts - prevents latch-up while maintaining system recoverability. |
| Peak-current-mode control | Provides inherent line/load regulation and simplifies compensation with single Type-II network due to built-in slope compensation. |
Applications
| Flashlight Driver | Infrared Illuminator |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ2410GJ-AEC1 | Automotive-grade variant with AEC-Q100 qualification, extended -40°C to +125°C operating range, and enhanced ESD robustness (±8kV HBM). | Required for automotive cabin lighting or ADAS IR illuminators where qualification compliance is mandatory. | Select when functional safety (ISO 26262) or automotive environmental compliance drives design requirements. |
| LT3466-1EDD#TRPBF | Lower 1.5A max output, 1.2MHz switching, no integrated low-side FET (requires external Schottky), no NTC input, but offers adjustable frequency and spread-spectrum option. | Better suited for low-power, ultra-low-noise applications where EMI suppression outweighs efficiency and integration benefits. | Choose only if discrete rectifier control or frequency tuning is prioritized over board area and thermal performance. |
Compared with MP2410GJ-P, MPQ2410GJ-AEC1 adds automotive qualification at higher cost and identical electrical specs, while LT3466-1EDD sacrifices integration and thermal management for flexibility in noise-sensitive designs - making MP2410GJ-P optimal for cost-, size-, and thermal-constrained consumer and industrial LED systems.

FAQ
What is the minimum input voltage required to start up MP2410GJ-P?
The MP2410GJ-P has a guaranteed turn-on threshold of 3.5V (typical 3.7V) on VIN with hysteresis of 0.12V. Startup occurs only when both VIN exceeds this threshold and EN/DIM voltage rises above 0.545V. Below 3.5V, UVLO holds the device in shutdown regardless of EN/DIM state.
Can MP2410GJ-P drive more than 2A of LED current?
No - the device is rated for up to 2A continuous output current under specified thermal conditions (TA ≤ 85°C, θJA = 100°C/W). Attempting higher currents causes thermal shutdown or current-limit activation. For >2A applications, consider parallel configurations or higher-current alternatives like MP2451.
How does the NTC pin function without an external thermistor?
If left unconnected, the NTC pin floats and the internal current source pulls it toward ~1.25V, disabling thermal foldback and allowing full output current. To enable temperature-based current reduction, a standard 10kΩ NTC thermistor must be connected between NTC and GND.
Is MP2410GJ-P compatible with ceramic output capacitors?
Yes - the MP2410GJ-P is optimized for ceramic output capacitors (X5R/X7R dielectric, ≥10µF, low-ESR). Its Type-II compensation and peak-current-mode architecture ensure stability with ceramic-only output networks, eliminating need for electrolytic or tantalum capacitors.
What happens during an LED short-circuit event?
Upon LED+–LED− short, the MP2410GJ-P detects overcurrent via IOCP (3.6–7A threshold), disables both MOSFETs for 2.4ms, then soft-starts again. If the fault persists, it repeats hiccup mode indefinitely - preventing damage while maintaining system observability through repeated fault pulses.
Does MP2410GJ-P support PWM dimming in addition to analog dimming?
No - MP2410GJ-P implements analog dimming only via DC voltage on EN/DIM. PWM dimming is not supported; applying PWM to EN/DIM causes erratic behavior due to internal 22ms shutdown delay and lack of synchronization circuitry.
What is the recommended layout practice for the BST capacitor?
A 0.1µF X7R ceramic capacitor must be placed directly between BST and SW pins with minimal trace length and no vias. This capacitor supplies gate drive energy for the high-side MOSFET; poor placement causes insufficient bootstrap voltage and premature switch failure.
