Monolithic Power Systems Inc. EV28200-G-00A

Overview

EV28200-G-00A from Monolithic Power Systems is an evaluation board for the MP28200GG ultra-low-I_Q step-down switching regulator, designed to demonstrate 200mA output at selectable voltages (0.8V–3.3V) with 500nA quiescent current, 1.5MHz switching frequency, and QFN12 (2×2mm) IC integration in a 6.3cm × 6.3cm PCB format.

For engineers reviewing the EV28200-G-00A datasheet, EV28200-G-00A pinout, EV28200-G-00A application, or EV28200-G-00A equivalent, this board enables rapid validation of low-power battery-powered system power delivery, voltage selection via CTRL pin logic, transient response under microampere load conditions, and thermal performance of the MP28200GG IC in real-world layout.

Technical Context

The EV28200-G-00A implements the MP28200GG's constant-on-time (COT) control architecture, enabling fast load-transient response without external compensation. It supports 7 discrete output voltages selected by 3-bit CTRL pin states (CTRL1–CTRL3), with automatic hiccup-mode short-circuit protection and thermal shutdown.

Tested with VIN = 3.6V, L1 = 2.2µH, CIN/COUT = 10µF each, the board validates tight regulation (±1% typical), 100% duty-cycle operation in dropout, and sub-µA standby current-critical for wearables and IoT edge nodes requiring multi-week battery life.

FAQ

What input voltage range is supported on the EV28200-G-00A board?

The board accepts 2.0 V to 5.5 V DC input, matching the MP28200GG's operational range. When VIN falls below 3.3 V, the documentation recommends increasing input capacitance to maintain stability-verified using two 10 µF X5R 0603 ceramics (GRM188R60J106ME47D) per the BOM.

How are output voltages selected on this evaluation board?

Voltage selection uses three dedicated CTRL pins (CTRL1–CTRL3) configured as binary inputs: grounding or pulling high to VIN sets one of seven discrete outputs (0.8 V–3.3 V) or disables the regulator. No external programming interface or firmware is required-selection is purely hardware-based and immediate.

Does the EV28200-G-00A include thermal protection validation?

Yes-the board integrates the MP28200GG's internal thermal shutdown circuitry. Test results confirm automatic recovery after temperature reduction, and the PCB layout (including exposed thermal pad on U1) is optimized for heat dissipation in ambient temperatures up to +25°C during full-load operation.

Can the EV28200-G-00A be used to evaluate light-load efficiency?

Absolutely-the board demonstrates the MP28200GG's 500 nA I_Q in practice, enabling direct measurement of efficiency down to 1 µA load current. This makes it ideal for validating battery runtime in always-on, intermittently active applications like BLE beacons or environmental sensors.

Is the MP28200GG IC soldered to the board, and is rework supported?

Yes-the MP28200GG is permanently mounted in its QFN12-2×2mm package with exposed thermal pad. The board follows MPS-recommended solder profile and pad layout, and the BOM specifies RoHS-compliant, halogen-free components-supporting controlled rework using standard hot-air stations and stencil-reflow processes.

What external components are included on the EV28200-G-00A board?

The board includes all critical passives: two 10 µF/6.3 V X5R ceramic capacitors (C1, C2), one 2.2 µH shielded power inductor (L1, DFE201612P-2R2M), one 100 kΩ precision film resistor (R1), and three 0603 tact switches for CTRL pin control-all sourced from Murata, Würth, and ROYALOHM per the official BOM.
