Monolithic Power Systems Inc. PKT-MEZDPD4506A-84F2

Overview

PKT-MEZDPD4506A-84F2 from Monolithic Power Systems is an evaluation kit for the mEZDPD4506A programmable 45V input, 0.6–22V output, 6A buck DC/DC power module. It includes the EVmEZDPD4506A-00A evaluation board, one pre-configured mEZDPD4506A-0000 module, EVKT-USBI2C-02 USB-to-I²C interface, and Tdrive-mEZDPD4506A USB thumb drive with Virtual Bench Pro 2.2 GUI software. Designed for rapid digital power validation in industrial and embedded power design labs.

For engineers reviewing the PKT-MEZDPD4506A-84F2 datasheet, PKT-MEZDPD4506A-84F2 pinout, PKT-MEZDPD4506A-84F2 application, or PKT-MEZDPD4506A-84F2 equivalent, this kit enables full I²C-based configuration of output voltage, switching frequency (600 kHz default), current limit, protection thresholds, and loop compensation - all without hardware modification.

Technical Context

The PKT-MEZDPD4506A-84F2 supports end-to-end digital power evaluation via I²C communication between the host PC (running Virtual Bench Pro 2.2) and the mEZDPD4506A module mounted on the EVmEZDPD4506A-00A board. The board provides access to VIN (4–45 V), VOUT (0.6–22 V), EN, PG, SDA, SCL, and sense terminals (VINSEN±, VOUTSEN±).

It integrates a complete 64 mm × 64 mm reference design with dual 22 µF output capacitors (C2A/C2B), eight 10 µF input capacitors (CIN1–CIN8), 4.7 µH power inductor (L2), and EMI filter components. Efficiency reaches 94.4% at 24 V_IN/12 V_OUT/6 A with 600 kHz switching.

FAQ

Is the mEZDPD4506A module included with PKT-MEZDPD4506A-84F2 pre-programmed?

Yes. The kit includes one mEZDPD4506A-0000 module factory-configured for 3.3 V output, 600 kHz switching frequency, and default protection thresholds. All parameters remain fully reprogrammable via I²C using Virtual Bench Pro 2.2.

What is required to establish communication between the host PC and the evaluation board?

A Windows PC running Virtual Bench Pro 2.2, the EVKT-USBI2C-02 USB-to-I²C dongle (included), and the 10-pin ribbon cable (included) are required. No external power supply or firmware flashing is needed - the GUI auto-detects the device upon connection.

Can PKT-MEZDPD4506A-84F2 support output voltages below 1.0 V?

Yes. The mEZDPD4506A supports 0.6 V to 22 V output range in 10 mV increments. For sub-1.0 V operation, use VOUTSEN+/- feedback routing and ensure proper PCB layout per the mEZDPD4506A datasheet's low-voltage stability guidelines.

Does the kit include hardware for remote monitoring of output current and temperature?

No. Real-time current and temperature telemetry require reading internal ADC registers via I²C - the mEZDPD4506A integrates these sensors but does not expose analog outputs. Virtual Bench Pro 2.2 displays live readings when connected.

Is the EVmEZDPD4506A-00A board RoHS-compliant and halogen-free?

Yes. Per Monolithic Power Systems' product compliance documentation, the EVmEZDPD4506A-00A evaluation board meets RoHS Directive 2011/65/EU and IEC 61249-2-21:2011 halogen-free requirements.

Can multiple PKT-MEZDPD4506A-84F2 kits be used simultaneously on one PC?

Yes. Virtual Bench Pro 2.2 supports multi-device enumeration via unique I²C addresses. Each mEZDPD4506A module can be assigned a distinct address (0x60–0x67) using the ADDR pin strap before power-up.
