Monolithic Power Systems Inc. EV5512-V-00A

Overview

EV5512-V-00A from Monolithic Power Systems is an evaluation board designed to demonstrate the MP5512 peak power assist and energy backup IC for AI-enabled speakers and SSDs. It supports 12V input, 35V programmable storage voltage, 6.1V input power-fail threshold, 7.8V bus backup regulation, and 3A max release current - enabling brown-out prevention in smart speakers and controlled data backup during power loss in SSDs.

For engineers reviewing the EV5512-V-00A datasheet, EV5512-V-00A pinout, EV5512-V-00A application, or EV5512-V-00A equivalent, this board provides validated reference design, test waveforms, BOM with Murata/Yageo/Coilcraft components, thermal layout guidance, and quick-start enable/disable sequencing - all critical for rapid integration of MP5512-based energy storage systems.

Technical Context

The EV5512-V-00A implements a complete energy storage and management reference design centered on the MP5512 QFN28 IC. It integrates boost-mode capacitor charging (up to 35V), input hot-swap with 14mΩ MOSFET, reverse-current blocking, and buck-mode energy release with internal 140mΩ/110mΩ switches - all coordinated via analog control loops without external microcontroller dependency.

Board-level features include adjustable PFI threshold (via R1/R2), programmable VSTRG (R5/R6), regulated VRLS (R3/R4), slew-controlled VB startup, and real-time current monitoring. Test conditions are fully documented: VIN=12V, TA=25°C, L1=10μH, POUT=20W, with waveform capture across EN, ENCH, PFI, VB, VS, and IB signals.

FAQ

What is the primary function of the EV5512-V-00A evaluation board?

The EV5512-V-00A is a fully assembled and tested reference platform for the MP5512 IC. Its purpose is to validate peak power assist in AI speakers (preventing brown-out during voice processing bursts) and controlled energy release for SSD data backup during unexpected power loss - using real-world component values and layout practices.

Does the board support adjustable storage voltage and power-fail thresholds?

Yes. VSTRG is set via resistor divider R5/R6 (0.8V reference), enabling programming up to 40V. VPFI is configured with R1/R2, allowing precise adjustment of the input power-fail detection point - both verified in the schematic and test report with 6.1V default calibration.

Can the EV5512-V-00A be used to evaluate thermal performance?

Yes. The board uses the MP5512's QFN28 package with exposed thermal pad, includes thermal vias under U1, and documents temperature-sensitive operation in Rev.1.2. Layout files (top/bottom layers) and component placement support thermal imaging and IR measurement during sustained 3A release tests.

What external components must be added to use the board for SSD backup testing?

No additional components are required for basic SSD backup validation. The board includes C4B (150μF/50V electrolytic) as the main storage capacitor, D1 (DFLS240L Schottky diode) for reverse-blocking, and L1 (10μH inductor). Only load connection to VB/GND and input to VIN/GND is needed to replicate SSD backup behavior.

Is the MP5512 IC on the board pre-programmed or configurable via pins?

The MP5512 is pin-configurable only - no firmware or one-time-programmable memory. All key parameters (VSTRG, VPFI, VRLS, slew rate, current limit) are set by external resistors (R1–R8) and capacitors per the datasheet. No programming tool or interface is required for configuration.

Are Gerber files and schematic available for this evaluation board?

Yes. The Rev.1.2 document includes top silk, top layer, and bottom layer PCB layout figures (Pages 5–6), full schematic (Page 2), and BOM with manufacturer part numbers. These are provided by MPS for design reuse, layout verification, and derivative board development.
