Monolithic Power Systems Inc. EVQ2013-J-Q-G-00A

Overview

EVQ2013-J-Q-G-00A from Monolithic Power Systems is a fully assembled and tested evaluation board for the MPQ2013 low-quiescent-current linear regulator, designed to validate 5V/150mA regulation from 6–40V input in high-voltage battery systems. It supports three package variants (TSOT23-5, QFN6-2×2mm, QFN8-3×3mm) and features ±2% output accuracy, 620mV dropout at full load, and 3.2µA quiescent current.

For engineers reviewing the EVQ2013-J-Q-G-00A datasheet, EVQ2013-J-Q-G-00A pinout, EVQ2013-J-Q-G-00A application, or EVQ2013-J-Q-G-00A equivalent, this board enables rapid validation of MPQ2013 performance across input voltage range, thermal shutdown behavior, load regulation, and FB-divider configuration under real-world conditions.

Technical Context

The EVQ2013-J-Q-G-00A implements a fixed 5V output configuration using external resistor dividers (2.4MΩ/768kΩ) to set the feedback reference, compatible with the MPQ2013's 1.215V internal reference. Each of the three onboard IC footprints-U1 (TSOT23-5), U2 (QFN8), and U3 (QFN6)-is independently selectable via jumper pairs (JP1–JP6) to evaluate package-specific thermal and layout effects.

Board-level design includes input/output ceramic capacitors (1µF/50V and 4.7µF/25V), low-ESR X7R/X5R dielectrics, and precision 1% film resistors to ensure stable regulation and accurate load-step response testing across -40°C to +125°C junction temperature range.

FAQ

What IC packages does the EVQ2013-J-Q-G-00A support?

The board supports three MPQ2013 variants: MPQ2013GJ in TSOT23-5, MPQ2013GQ in QFN8 (3×3mm), and MPQ2013GG in QFN6 (2×2mm). Selection is made via jumper pairs JP1–JP6, allowing direct comparison of thermal performance, PCB footprint, and solderability across packages without redesign.

How is the 5V output set and verified on this board?

The 5V output is set using a precision 2.4MΩ/768kΩ resistor divider network tied to the FB pin, yielding V_OUT = 1.215V × (1 + 2.4M/768k) = 5.00V. Output accuracy is verified as ±2% across input range and temperature, confirmed by MPS test reports and on-board test points TP1 (VOUT) and TP2 (FB).

Does the board include thermal protection validation features?

Yes - the board uses the MPQ2013's internal thermal shutdown circuitry, which activates at ~150°C junction temperature. Test results in the reference document confirm automatic recovery after cooldown, and the board's copper pour and component placement allow direct IR thermography of each IC footprint during sustained 150mA load testing.

Can the EVQ2013-J-Q-G-00A be used to evaluate adjustable-output configurations?

No - this board is configured exclusively for fixed 5V output. The feedback resistors are populated permanently; no provision exists for removing or replacing them to implement adjustable output. For adjustable evaluation, refer to MPS's MPQ2013 evaluation schematics or custom board design using the MPQ2013's FB pin interface.

What are the recommended input capacitor requirements per MPS guidelines?

MPS specifies ≥1µF X7R ceramic input capacitance with ≤50V rating, placed within 5mm of the VIN/GND pins. This board meets that requirement with 1206-format 1µF/50V capacitors (C1/C5/C9) and low-ESR layout routing, ensuring stability under fast transient loads and minimizing input ripple propagation.

Is RoHS compliance documented for all components on the board?

Yes - all MPS ICs (MPQ2013GJ/GQ/GG) are lead-free and RoHS-compliant per MPS Quality Assurance documentation. Passive components (Murata/Yageo) listed in the BOM also carry RoHS declarations, and the board itself is assembled using lead-free solder per IPC J-STD-001 Class 2 standards.
