Monolithic Power Systems Inc. EV2013A-33-J-Q-G-00A

Overview

EV2013A-33-J-Q-G-00A from Monolithic Power Systems is a fully assembled and tested evaluation board for the MPQ2013AGQ-33 (QFN8-3×3mm) and MPQ2013AGG-33 (QFN6-2×2mm) 3.3V, 150mA low-quiescent-current linear regulators. It supports 4.3V–40V input, delivers ±2% output accuracy with QFN8 or ±4% with QFN6, and features 700mV dropout at full load-enabling operation in high-voltage battery-powered industrial and automotive systems.

For engineers reviewing the EV2013A-33-J-Q-G-00A datasheet, EV2013A-33-J-Q-G-00A pinout, EV2013A-33-J-Q-G-00A application, or EV2013A-33-J-Q-G-00A equivalent, this board enables rapid validation of MPQ2013A-33 regulator performance under real-world line/load transients, thermal shutdown behavior, short-circuit recovery, and adjustable UVLO/VOUT configurations.

Technical Context

The EV2013A-33-J-Q-G-00A implements dual-package support via jumper-selectable configuration: JP2+JP5 enables MPQ2013AGQ-33 (QFN8), while JP3+JP6 enables MPQ2013AGG-33 (QFN6). Each IC variant integrates internal feedback resistors for fixed 3.3V output and supports external resistor dividers for adjustable VOUT or VIN UVLO threshold tuning.

Test results confirm stable 3.3V regulation across 0–150mA load (±0.005V variation at VIN=4.3V), <700mV dropout at 150mA, and robust transient response-e.g., 20ms recovery from short-circuit to 150mA load-with EN control enabling 1.48V turn-on/1.26V turn-off thresholds.

FAQ

What ICs does the EV2013A-33-J-Q-G-00A evaluate?

The board evaluates two Monolithic Power Systems regulators: MPQ2013AGQ-33 (QFN8-3×3mm package) and MPQ2013AGG-33 (QFN6-2×2mm package). Jumper selection (JP2+JP5 or JP3+JP6) determines which IC is active on the board during testing.

How do I configure the board for adjustable output voltage?

Remove the internal feedback resistors and use external R7/R8 (for MPQ2013AGQ-33) as shown in the schematic. The formula VOUT = 1.215 × (1 + R7/R8) applies. R8 must be ≤1 MΩ at TA ≤105°C or ≤210 kΩ at TA ≤125°C to ensure minimum load current for stability.

Does the board support enable/disable control?

Yes-EN functionality is accessible via test pins. To activate EN control, remove resistor R5 (for QFN8) or R9 (for QFN6), then apply >1.48 V to turn on or <1.26 V to turn off the regulator. This allows precise system-level power sequencing.

What input capacitance is recommended for high-VIN operation?

When using input voltages ≥24 V or cable lengths >0.5 m between source and board, a damping capacitor must be installed at the VIN/GND terminals. This mitigates ringing and ensures stable startup and transient response per MPS test guidelines.

Can the board validate short-circuit protection behavior?

Yes-the board demonstrates full short-circuit characterization: entry, steady-state current limiting (~180 mA), and recovery within 20 ms when load transitions from short to 150 mA. Waveforms for all phases are documented in the Rev. 1.0 test report.

Is UVLO threshold configurable?

Yes-via external resistor divider R5/R6 (for MPQ2013AGQ-33). Using the formula R6 = R5 / (VIN_UVLO_F / 1.26 − 1), users can set falling UVLO thresholds (e.g., 4.5 V with R5 = 2 MΩ, R6 = 778 kΩ) to prevent operation below safe battery voltage.
