Monolithic Power Systems Inc. EVL2460-J-00A

Overview

EVL2460-J-00A from Monolithic Power Systems is a fully assembled evaluation board for the MP2460GJ synchronous step-down converter IC, demonstrating 12V/0.6A regulated output from 12.5–45V input, operating at 1.7MHz with >90% efficiency and 0.1% output voltage ripple. It integrates the TSOT23-6 MP2460GJ, MPS MPL-SE6040-220 inductor, and optimized ceramic/electrolytic output capacitance for industrial and battery-powered power conversion validation.

For engineers reviewing the EVL2460-J-00A datasheet, EVL2460-J-00A pinout, EVL2460-J-00A application, or EVL2460-J-00A equivalent, this board enables rapid functional verification of high-voltage DC-DC regulation, enable-controlled startup/shutdown sequencing, short-circuit hiccup recovery, and low-quiescent-current (1μA) operation under light-load and shutdown conditions.

Technical Context

The EVL2460-J-00A implements a current-mode controlled buck topology using the MP2460GJ IC, which integrates 420mΩ high-side and 220mΩ low-side MOSFETs. Its fixed 1.7MHz switching frequency enables compact magnetics and low-output-ripple performance with ceramic capacitors.

Board-level design supports wide-input operation (4.5–45V), adjustable output (0.8V to 98% VIN), low-dropout mode below 12.5V, and precision cycle-by-cycle current limiting without external sense resistors - all validated per test data at VIN = 24V, VOUT = 12V, TA = 25°C.

FAQ

What input voltage range is supported on the EVL2460-J-00A?

The board operates with 12.5V to 45V DC input, matching the MP2460GJ's 4.5V–45V rating. Minimum functional input is 12.5V due to onboard feedback resistor network setting VOUT = 12V; lower outputs require reconfiguration per datasheet Section 8.2.2.

Can the output voltage be adjusted, and how?

Yes - VOUT is set by R1 (10.7kΩ) and R2 (150kΩ) in a resistive divider from FB to GND. To change output, replace R2 per Equation 1 in the MP2460 datasheet: VOUT = 0.8V × (1 + R2/R1). The board supports outputs from 0.8V up to 98% of VIN.

Does the board include enable functionality, and what are the logic thresholds?

Yes - the EN pin accepts TTL/CMOS-compatible signals. Driving EN above 2.0V enables regulation; pulling EN below 1.0V disables the converter and reduces quiescent current to 1μA. A 0Ω jumper (R6) connects EN to VIN by default for automatic startup.

What protection features are demonstrated on this board?

All MP2460GJ protections are active: cycle-by-cycle current limiting, hiccup-mode short-circuit response, thermal shutdown (triggered at ~150°C junction), and overvoltage clamp. Test waveforms in the user guide confirm recovery from 0A → short → 0.6A load transitions within 2ms.

Is an external inductor required, or is one included?

A fully populated MPS MPL-SE6040-220 22μH shielded inductor is soldered to the board. Its 97mΩ DCR and 2.35A saturation current ensure stable 0.6A operation across temperature and input range without derating.

How is output stability verified on this evaluation board?

Stability is confirmed via 0.1% peak-to-peak output voltage ripple at 0.125A and 0.4A loads, measured differentially across C6 (22μF X7R) and C10 (470μF electrolytic). Phase margin exceeds 60° per internal compensation design, eliminating need for external compensation components.
