Monolithic Power Systems Inc. EV8714-LE-00A

Overview

EV8714-LE-00A from Monolithic Power Systems is an evaluation board designed to demonstrate the MP8714 synchronous step-down converter, a 10A, 1V output DC/DC regulator operating from 4.5V–17V input. It integrates high-side (26mΩ) and low-side (11mΩ) MOSFETs, supports 200kHz–2MHz external clock synchronization, and features open-drain power good (PG), programmable soft-start, and full protection including OVP and thermal shutdown.

For engineers reviewing the EV8714-LE-00A datasheet, EV8714-LE-00A pinout, EV8714-LE-00A application, or EV8714-LE-00A equivalent, this board enables rapid validation of MP8714 performance in high-current, space-constrained point-of-load designs-especially for flat-panel displays, set-top boxes, and distributed power systems requiring stable 1V/10A delivery.

Technical Context

The EV8714-LE-00A implements the MP8714 in a fully assembled, tested layout with 1.5µH shielded inductor (Wurth 744311150), four 22µF X5R 0805 output capacitors, and optimized input/output filtering using Murata GRM series ceramics. It uses current-mode control for fast transient response and loop stability under dynamic load steps up to 10A.

Board-level features include EN/SYNC pin access for enable control and external clock synchronization, PG signal monitoring, and resistor-programmable soft-start via R1 (80.6kΩ). All critical power paths follow tight thermal and current-loop design rules per MPS reference layout guidelines.

FAQ

What input voltage range is supported on the EV8714-LE-00A?

The board accepts 4.5V to 17V DC input, matching the MP8714's operational range. It has been validated at 12V nominal with 10A load, and supports both constant-voltage and transient input conditions per MPS test reports. Input filtering uses two 22µF X5R 1206 capacitors plus 0.1µF and 0.47µF ceramics for broadband noise suppression.

How is output voltage set on this evaluation board?

VOUT is fixed at 1V by internal feedback resistor divider inside the MP8714GLE IC; no external resistor network is required. The board does not support adjustable output-this is a dedicated 1V/10A demonstration platform aligned with CPU core rail requirements.

Can the EV8714-LE-00A be synchronized to an external clock?

Yes. The SYNC pin (Pin 10 of U1) accepts 200kHz–2MHz CMOS-level clock signals. When driven, the MP8714 locks its switching frequency to the external source, reducing EMI through deterministic spectral placement-verified in MPS Rev.1.0 test waveforms.

What thermal performance can be expected under full 10A load?

At TA = 25°C, VIN = 12V, VOUT = 1V, the board achieves <90°C peak temperature on the MP8714 QFN-14 package under continuous 10A load, per MPS thermal imaging data. Copper pour and thermal vias beneath the IC ensure efficient heat transfer to inner layers and bottom-side ground plane.

Does the board provide access to enable and power-good signals?

Yes. EN (Pin 13) and PG (Pin 7) are brought out to 0.1"-spaced headers. EN requires >1.5V to activate and <1.03V to disable; PG is open-drain and pulls low when VOUT deviates >±6% from 1V-both verified with oscilloscope capture in the official test report.

Are all components on the board RoHS-compliant and lead-free?

Yes. All listed BOM components-including MP8714GLE, Wurth inductor 744311150, and Murata GRM capacitors-are RoHS-compliant, halogen-free, and meet MPS green status requirements as confirmed in the Bill of Materials and MPS Quality Assurance documentation.
