Product details
Overview
MP2410GJ-Z from Monolithic Power Systems is a 24V-input, 2A-output, 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-Z datasheet, MP2410GJ-Z pinout, MP2410GJ-Z application, or MP2410GJ-Z equivalent, key selection criteria include its 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-Z implements peak current mode control with internal error amplifier comparing FB voltage against a precision 100mV reference, generating COMP voltage to regulate high-side switch conduction time. Its fixed 1MHz oscillator enables compact external LC filtering while maintaining fast transient response for dynamic LED brightness changes.
It integrates dual protection logic: cycle-by-cycle current limiting (5.5A typical OCP threshold) and fault-triggered hiccup-mode restart (2.4ms timer), plus independent NTC monitoring (0.82V low-threshold, 1.25V high-threshold) and thermal shutdown at 150°C with 60°C hysteresis - all without external supervision circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.2V to 24V - supports 12V/24V industrial rails and battery-powered systems down to single Li-ion cell with boost pre-regulator. |
| Max Output Current | 2A continuous - drives up to 6-series white LEDs at 350mA or 2-series IR LEDs at full scale without external current amplification. |
| Switching Frequency | Fixed 1MHz - enables use of ≤4.7µH inductors and 10µF ceramic input/output capacitors for minimal board area. |
| Feedback Reference | 100mV ±7mV - allows precise current setting with 50mΩ sense resistor (±1% tolerance yields ±2% LED current accuracy). |
| Internal MOSFET RDS(on) | High-side: 100mΩ @ 5V; Low-side: 80mΩ @ 5V - achieves ≥97% efficiency at 12VIN/5.9VOUT/1.5A without heatsinking. |
| Analog Dimming Range | VEN/DIM = 0.7V to 1.44V - linearly scales output current from minimum to full scale, enabling smooth brightness control without PWM artifacts. |
| Thermal Protection | NTC interface with 0.41V shutdown threshold and 110mV hysteresis - provides programmable LED temperature derating using standard 10kΩ NTC thermistors. |
Pinout & Package
MP2410GJ-Z is housed in a thermally enhanced TSOT23-6 package (2.9mm × 1.6mm × 0.85mm), optimized for high-power density LED driver layouts with exposed pad for GND thermal conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Power and signal reference ground | Primary return path for LED current, SW node, and internal bias - must be connected to large copper pour for thermal and noise control. |
| 2 - SW | Switch node | Drives external inductor; carries high di/dt ripple current - requires short, wide trace routing away from FB and NTC nodes. |
| 3 - VIN | Main power input | Accepts 4.2–24V unregulated supply; requires local 10µF X5R/X7R ceramic capacitor placed within 2mm of pin. |
| 4 - BST | Bootstrap supply | Connects to SW via 0.1µF ceramic capacitor to generate floating gate drive for high-side MOSFET - critical for 100% duty cycle capability. |
| 5 - EN/DIM | Enable and analog dimming input | DC voltage-controlled on/off and brightness; 0.59V turn-on threshold and 0.31V turn-off threshold enable simple microcontroller GPIO interfacing. |
| 6 - FB | Current-sense feedback | Monitors voltage across external sense resistor; 100mV reference sets LED current as ILED = 0.1V / RSENSE. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated 80mΩ low-side FET eliminates external Schottky loss, enabling >97% efficiency at 1.5A without thermal derating. |
| Inherent open-LED protection | No external components needed - device enters 94% max duty cycle mode when FB floats, limiting output voltage to safe level below VIN. |
| NTC-based thermal foldback | Dedicated NTC pin with internal 58μA pull-up enables direct connection of standard thermistors for LED junction temperature regulation. |
| Auto-restart hiccup mode | 2.4ms fault timer forces soft-start recovery after SCP, open-LED, or overtemperature events - prevents latch-up during intermittent faults. |
| 100mV precision reference | Guaranteed 93–107mV over -40°C to +125°C ensures ±2% LED current accuracy across automotive and industrial temperature ranges. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED current regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ2410GJ-A | Automotive-grade AEC-Q100 qualified version with extended temp range (-40°C to +150°C) and enhanced ESD (4kV HBM). | Required for automotive cabin lighting or ADAS illuminators where qualification compliance is mandatory. | Select MPQ2410GJ-A only when AEC-Q100 certification and higher thermal margin are required; otherwise MP2410GJ-Z offers cost advantage. |
| LT3466-1EDD | 40V max input, 1.2A max output, 1.2MHz switching, no integrated low-side FET - requires external Schottky. | Suitable for higher-input industrial LED drivers where 24V+ operation or lower current suffices. | Choose LT3466-1EDD only if input exceeds 24V or design requires separate control of low-side conduction; MP2410GJ-Z provides better integration and efficiency at ≤24V/2A. |
Compared with MPQ2410GJ-A, MP2410GJ-Z trades automotive qualification for lower unit cost and identical electrical performance in commercial environments; versus LT3466-1EDD, it delivers higher output current and eliminates external rectifier losses - reducing BOM count and thermal stress in portable LED systems.

FAQ
What is the minimum input voltage required to start the MP2410GJ-Z?
The MP2410GJ-Z features under-voltage lockout (UVLO) with a turn-on threshold of 3.5V to 4.0V (typical 3.7V) and 0.12V hysteresis. Below 3.5V, the IC remains disabled; once VIN rises above the threshold, internal regulators initialize and the device begins soft-start sequence within milliseconds.
Can the MP2410GJ-Z drive LEDs in series or parallel configurations?
The MP2410GJ-Z is designed for constant-current regulation in series-connected LED strings only. Its feedback loop senses current via a single sense resistor between LED cathode and GND. Parallel LED strings require individual current-setting resistors and are not supported due to mismatch-induced current imbalance.
How does the NTC pin function for thermal protection?
The NTC pin sources a precise 58μA current into an external NTC thermistor. As temperature rises, NTC resistance drops, lowering the voltage at the pin. When voltage falls below 0.41V (shutdown threshold), the IC disables switching and reduces LED current to zero - providing programmable thermal foldback without external comparators.
What is the purpose of the BST pin and what capacitor value is recommended?
The BST pin supplies the floating gate drive for the internal high-side MOSFET. A 0.1µF X5R/X7R ceramic capacitor must be placed directly between BST and SW pins. This capacitor charges during low-side conduction and provides the ~5.1V gate-source voltage needed to fully enhance the high-side FET during each switching cycle.
Does the MP2410GJ-Z support PWM dimming in addition to analog dimming?
No - the MP2410GJ-Z supports analog dimming only via DC voltage on the EN/DIM pin (0.7V–1.44V range). It does not include dedicated PWM input circuitry or frequency synchronization capability. For PWM dimming, external circuitry or a different MPS part such as MP4000 must be used.
What failure protections are built into the MP2410GJ-Z?
The MP2410GJ-Z integrates five independent protections: cycle-by-cycle overcurrent limiting (5.5A threshold), open-LED detection (max 94% duty cycle clamping), output short-circuit protection (SCP), NTC-based thermal foldback, and junction thermal shutdown at 150°C with automatic 60°C hysteresis recovery.
Is the TSOT23-6 package RoHS-compliant and lead-free?
Yes - the MP2410GJ-Z is fully RoHS-compliant, lead-free, and halogen-free per MPS green policy. The TSOT23-6 package uses matte tin plating and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life at ≤30°C/85% RH.
