Monolithic Power Systems Inc. EV2236-J-00A

Overview

EV2236-J-00A from Monolithic Power Systems is an evaluation board designed to demonstrate the MP2236 - a 18V-input, 6A-output, synchronous step-down DC/DC converter with integrated 25mΩ/12mΩ MOSFETs, 600kHz switching frequency, and constant-on-time control in an 8-pin TSOT-23 package. It supports 3V–18V input, delivers tight regulation, fast transient response, and includes SCP, OCP, and thermal shutdown.

For engineers reviewing the EV2236-J-00A datasheet, EV2236-J-00A pinout, EV2236-J-00A application, or EV2236-J-00A equivalent, this board enables rapid validation of MP2236's load regulation, startup behavior, thermal performance, and protection sequencing under real-world PCB layout and component sourcing conditions.

Technical Context

The EV2236-J-00A implements the MP2236 IC in a fully assembled, tested configuration with optimized power stage layout, input/output capacitance, and feedback network. It operates across 3V–18V input and delivers up to 6A continuous output at adjustable VOUT (set by external resistor divider), leveraging the IC's internal 600mV reference and COT control for sub-10µs load-step response.

Board-level design includes thermal vias under the TSOT-23 footprint, ceramic input/output capacitors, and a single-layer feedback trace routed away from noisy switching nodes - all aligned with MPS's recommended layout guidelines for stability and EMI performance.

FAQ

What input voltage range is supported by the EV2236-J-00A board?

The board supports 3V to 18V DC input, matching the MP2236's rated operating range. Input is applied via screw terminal or solder pads, and the board includes reverse-polarity protection diode and 10µF/25V X7R ceramic input capacitor bank. Operation below 3V may disable UVLO; above 18V risks permanent damage to the IC.

Can the output voltage be adjusted, and how?

Yes - VOUT is set by an external resistor divider (R1/R2) connected to the FB pin per MP2236's 600mV reference. Default configuration yields 3.3V; changing R1/R2 values allows adjustment from ~0.6V to VIN × 0.8. The board provides test points and solder jumpers for easy reconfiguration without component replacement.

Does the board include thermal management features?

Yes - it uses a 2-layer PCB with 2oz copper, thermal vias under the MP2236's exposed pad, and direct copper pours connecting to ground plane. Measured junction temperature rise is ≤25°C at 6A/12V_IN/3.3V_OUT in still air, confirming effective heat dissipation without forced airflow.

Is the EV2236-J-00A RoHS-compliant and lead-free?

Yes - both the MP2236 IC and the EV2236-J-00A board are RoHS-compliant, halogen-free, and lead-free per MPS's quality policy. Certificate of Compliance and IPC-1752a material declarations are available upon request through Aetrix Electronics' technical support portal.

What documentation is provided with the board?

Aetrix ships EV2236-J-00A with the official MPS EVB User Guide (UM-2236), schematic PDF, PCB layout files (Gerber), BOM, and test report summarizing efficiency curves, load/line regulation, and thermal images. No firmware or software tools are included - the board is hardware-only.
