Monolithic Power Systems Inc. EV2013A-J-Q-G-00A

Overview

EV2013A-J-Q-G-00A from Monolithic Power Systems is a fully assembled and tested evaluation board for the MP2013A/MPQ2013A family of 40V-input, 150mA low-quiescent-current linear regulators. It supports dual QFN packages (QFN6-2×2mm and QFN8-3×3mm), delivers regulated +5V output across 6–40V input, and enables validation of dropout (620mV @150mA), ±2% output accuracy, and thermal shutdown in automotive and industrial power-supply designs.

For engineers reviewing the EV2013A-J-Q-G-00A datasheet, EV2013A-J-Q-G-00A pinout, EV2013A-J-Q-G-00A application, or EV2013A-J-Q-G-00A equivalent, this board provides verified test conditions for EN control, FB divider configuration, UVLO adjustment, load transient response, and thermal behavior under real-world 6–40V battery-fed systems.

Technical Context

The EV2013A-J-Q-G-00A implements two independent regulator configurations on one PCB: one with MPQ2013AGQ (QFN8) and another with MPQ2013AGG (QFN6), each with dedicated FB dividers (R7/R8 and R11/R12), EN biasing (R5/R6 and R9/R10), and input/output decoupling networks. Both paths share identical 1μF/50V input and 4.7μF/16V output ceramic capacitors per channel.

It supports configurable output voltage via external resistor dividers referenced to the 1.215V internal feedback reference, and allows UVLO threshold tuning using high-impedance EN-divider networks-enabling system-level brown-out protection at user-defined VIN falling thresholds (e.g., 4.5V with R3=2MΩ, R4=778kΩ).

FAQ

What ICs are populated on the EV2013A-J-Q-G-00A board?

The board contains two pre-soldered regulators: MPQ2013AGQ (QFN8-3×3mm) and MPQ2013AGG (QFN6-2×2mm), both AEC-Q100 qualified variants of the MP2013A series. Each has its own dedicated FB divider, EN network, and bypass capacitors - enabling side-by-side comparison of package thermal performance and layout sensitivity.

How do I configure the output voltage to 3.3V?

To set V_OUT = 3.3V, replace R8 (or R12) with a 1.40 MΩ 1% resistor while retaining R7/R11 = 2.4 MΩ, per the formula R8 = R7 / (V_OUT/1.215 V − 1). The board includes footprint pads and jumpers to support this change without soldering modifications to the IC itself.

Does the board support enable/disable control?

Yes - both regulators feature active-high EN pins accessible via test points and jumper-selectable pull-up resistors. To use external EN control, remove R5 (for MPQ2013AGQ) or R9 (for MPQ2013AGG), then apply >1.48 V to enable or <1.26 V to disable - matching the IC's specified EN threshold hysteresis.

Can I use this board to evaluate UVLO behavior?

Yes - the board includes optional UVLO divider networks (R5/R6 for MPQ2013AGQ; R9/R10 for MPQ2013AGG) that let you program the input undervoltage lockout falling threshold. For example, setting R5 = 2 MΩ and R6 = 778 kΩ configures UVLO to trigger at 4.5 V, protecting downstream circuitry during battery sag.

What capacitor types and values are used for input and output filtering?

The board uses 1 μF/50V X7R ceramic capacitors (1206) at VIN and 4.7 μF/16V X7R ceramics (0805) at VOUT for each regulator channel. These values meet MPQ2013A stability requirements per the datasheet and were validated with load-step transient testing showing <50 mV overshoot/undershoot at 150 mA steps.
