Monolithic Power Systems Inc. EV2013B-33-J-Q-G-00A

Overview

EV2013B-33-J-Q-G-00A from Monolithic Power Systems is a fully assembled and tested evaluation board for the MPQ2013BGQ-33 low-dropout linear regulator, designed to validate operation of 3.3V/150mA power delivery from 4.3V–40V input sources in high-voltage battery systems. It supports thermal shutdown, ±3% output accuracy, 700mV dropout at full load, and operates across –40°C to +125°C junction temperature.

For engineers reviewing the EV2013B-33-J-Q-G-00A datasheet, EV2013B-33-J-Q-G-00A pinout, EV2013B-33-J-Q-G-00A application, or EV2013B-33-J-Q-G-00A equivalent, this board enables rapid validation of MPQ2013BGQ-33 performance under real-world line/load transients, UVLO configuration, EN control, and short-circuit recovery - critical for automotive and industrial LDO qualification.

Technical Context

The EV2013B-33-J-Q-G-00A implements the MPQ2013BGQ-33 QFN8 (3×3 mm) regulator with fixed 3.3V output, internal 1.26V feedback reference, and resistor-divider-based UVLO configuration via R5/R6. It uses 1μF input and 4.7μF output ceramic capacitors per test conditions.

Board-level features include jumper-selectable IC variants (JP2/JP5), EN control interface (1.26V turn-off / 1.48V turn-on thresholds), exposed-pad thermal management, and test points for VIN, VOUT, GND, and EN - enabling direct oscilloscope probing of startup, load transient, and PSRR behavior up to 1 MHz.

FAQ

What ICs does the EV2013B-33-J-Q-G-00A evaluate?

The board evaluates three Monolithic Power Systems parts: MPQ2013BGQ-33 (AEC-Q100 qualified), MP2013BGQ-33 (commercial grade), and MPQ2013BGQ-33-AEC1 (automotive-grade variant). All share identical electrical specs and QFN8-3×3 package, differing only in qualification level and screening.

How do I configure UVLO on this board?

UVLO is configured using resistor divider R5/R6 between VIN and GND. With EN threshold fixed at 1.26V (falling) and 1.48V (rising), setting R5 = 2MΩ and R6 = 778kΩ achieves a 4.5V falling UVLO threshold. The Quick Start Guide provides the exact formula for custom thresholds.

Can I use this board to test EN functionality?

Yes. Remove solder jumper R5 to isolate the internal EN pull-up, then apply voltage to the EN test point: ≥1.48V turns the regulator on; ≤1.26V forces shutdown. This allows precise timing validation of enable sequencing in multi-rail systems.

What capacitor types and values are populated?

The board uses three 1μF/50V X7R ceramic capacitors (C1/C6/C11, 1206) at the input and three 4.7μF/16V X7R ceramics (C4/C9/C14, 0805) at the output - all Murata GRM/GCM series, matching the recommended layout and stability criteria in the MPQ2013BGQ-33 datasheet.

Does the board support short-circuit testing?

Yes. Test results on pages 5–7 confirm short-circuit entry, steady-state, and recovery behavior - including current limiting, thermal foldback, and automatic restart after fault removal - all measured with 12V input and direct output shorting.

Is thermal performance characterized?

Yes. The QFN8 package's exposed thermal pad is soldered to a dedicated copper pour on the bottom layer (Figure 2), and test data shows stable operation at 125°C junction under 150mA load with no derating - confirming suitability for sealed enclosures without forced airflow.
