Monolithic Power Systems Inc. EV2410A-J-00A

Overview

EV2410A-J-00A from Monolithic Power Systems is a high-efficiency evaluation board for the MP2410AGJ synchronous step-down LED driver IC, designed to drive two 5.9V white LEDs in series at 1.5A from an 8–24V input. It integrates peak current mode control, analog/PWM dimming, and full fault protection including open-LED, short-circuit, and thermal shutdown.

For engineers reviewing the EV2410A-J-00A datasheet, EV2410A-J-00A pinout, EV2410A-J-00A application, or EV2410A-J-00A equivalent, this board enables rapid validation of MP2410AGJ-based LED driver designs under real-world load, efficiency, and dimming performance conditions.

Technical Context

The EV2410A-J-00A implements a fixed 1MHz synchronous buck topology with internal 100mΩ high-side MOSFET and 80mΩ low-side synchronous rectifier. It supports both analog dimming (0.6–1.5V EN/DIM input) and PWM dimming (duty-cycle controlled via EN/DIM pin).

Tested with 4.7µH inductor and two-series WLEDs (5.9V, 1.5A), it delivers up to 95% efficiency at VIN = 12V and maintains tight line/load regulation across its 8–24V input range and full output current range.

FAQ

What input voltage range does the EV2410A-J-00A support?

The board operates from 8V to 24V DC input, matching the MP2410AGJ IC's rated input range. This allows direct connection to common industrial supplies, 12V automotive batteries, or regulated lab sources without additional conditioning stages.

How is LED current set on this evaluation board?

LED current is set by the sense resistor R1 (100mΩ), which establishes 1.5A full-scale current per the MP2410AGJ's 100mV feedback reference. The board is pre-configured for 1.5A; changing R1 value adjusts the current proportionally.

Can the EV2410A-J-00A drive more than two LEDs in series?

No-the board is optimized for two-series WLEDs (5.9V total V_F). Driving higher-V_F strings would exceed the MP2410AGJ's maximum output voltage capability and risk regulation loss or thermal stress without component changes.

Does the board support both analog and PWM dimming simultaneously?

No-only one dimming method may be used at a time. Analog dimming requires a DC voltage (0.6–1.5V) on EN/DIM; PWM dimming requires a square wave with high >1.5V and low <0.6V. Concurrent signals are not supported and may cause unstable operation.

What thermal performance can be expected during continuous 1.5A operation?

At TA = 25°C and VIN = 12V, the board achieves up to 95% efficiency, limiting power dissipation. Measured junction temperature rise remains within safe limits (<60°C above ambient) due to copper pour layout and TSOT23-6 IC thermal pad soldering-no heatsink required for nominal operation.

Is the EV2410A-J-00A RoHS-compliant and lead-free?

Yes-both the MP2410AGJ IC and all bill-of-materials components on the EV2410A-J-00A board are RoHS-compliant, lead-free, and halogen-free, meeting global environmental compliance standards as confirmed by MPS documentation.
