Monolithic Power Systems Inc. EVM3830-QV-00A

Overview

EVM3830-QV-00A from Monolithic Power Systems is an evaluation board for the MPM3830GQV synchronous step-down DC/DC module-a 3A, 1.2 MHz, integrated-inductor buck converter with 2.7–6 V input and fixed 1.2 V output in a 3.0×5.0×1.6 mm QFN package-designed to demonstrate high-efficiency power delivery in space-constrained portable and storage applications.

For engineers reviewing the EVM3830-QV-00A datasheet, EVM3830-QV-00A pinout, EVM3830-QV-00A application, or EVM3830-QV-00A equivalent, this board enables rapid validation of MPM3830GQV's constant-on-time control, ultra-low 40 µA quiescent current, hiccup-mode short-circuit protection, and 100% duty-cycle dropout capability under real load conditions.

Technical Context

The EVM3830-QV-00A implements the MPM3830GQV IC in a fully assembled, tested layout optimized for minimal external components: only two 22 µF ceramic input/output capacitors and three 100 kΩ resistors (R1–R3) are populated, supporting both fixed 1.2 V and adjustable 0.6–6 V output configurations via FB divider.

It operates at 1.2 MHz switching frequency with COT (Constant-On-Time) control architecture, delivering fast transient response and light-load efficiency improvement through frequency scaling-verified at VIN = 5 V, VOUT = 1.2 V, TA = 25 °C per test reports on the board.

FAQ

What is the default output voltage of the EVM3830-QV-00A?

The board is configured by default for 1.2 V output using R2 = 100 kΩ and R1 = 100 kΩ in the feedback divider network. This matches the fixed-output variant of the MPM3830GQV and is verified per the quick start guide and schematic on Rev. 1.0 documentation.

Can the EVM3830-QV-00A be used to evaluate adjustable-output operation?

Yes-the board supports adjustable output from 0.6 V to 6 V by modifying R1 and R2 values per the formula VOUT = 0.6 × (1 + R1/R2). The BOM includes placeholders and silk-screened labels for R1, R2, and R3 to enable easy reconfiguration without soldering changes.

Does the EVM3830-QV-00A include the MPM3830GQV IC?

Yes-U1 on the board is the MPM3830GQV in a 3.0×5.0×1.6 mm QFN package, as confirmed by the Bill of Materials and schematic. It integrates power MOSFETs, driver, PWM controller, and shielded inductor in a single surface-mount module.

What input voltage range is supported during evaluation?

The board supports 2.7 V to 6 V DC input, consistent with the MPM3830GQV's rated operating range. Testing data in the documentation uses VIN = 5 V, but full-range validation-including dropout at 100% duty cycle-is enabled across the specified range.

Is thermal performance characterized on this evaluation board?

Yes-thermal shutdown protection is implemented in the MPM3830GQV and verified on the EVM3830-QV-00A. Layout follows MPS-recommended copper pour and thermal pad guidelines, and test reports confirm stable operation up to 3 A continuous load at TA = 25 °C with no forced airflow.

Are input and output capacitors included on the board?

Yes-the board populates three 22 µF, 10 V, X5R ceramic capacitors (C1, C2, C2A) per the BOM: two serve as input/output bulk capacitance, and one provides additional output filtering. All use TDK C2012X5R1A226K in 0805 package.
