Product details
Overview
EV4430-L-00A from Monolithic Power Systems is an end-of-life evaluation board for the MP/MPQ4430GL synchronous step-down converter IC, supporting 3.3V–36V input and delivering 3.3V/3.5A output with programmable 350kHz–2.5MHz switching frequency, AAM light-load mode, and integrated 90mΩ/40mΩ MOSFETs. It is used to validate power delivery in automotive and industrial DC-DC designs.
For engineers reviewing the EV4430-L-00A datasheet, EV4430-L-00A pinout, EV4430-L-00A application, or EV4430-L-00A equivalent, this board enables rapid functional validation of the MPQ4430GL's voltage regulation, soft-start, sync capability, power-good signaling, and thermal behavior under real load conditions.
Technical Context
The EV4430-L-00A implements the MPQ4430GL's current-mode control architecture with external frequency programming via RFREQ, selectable forced CCM or AAM operation via SYNC pin logic, and programmable soft-start using a 4.7nF capacitor on SS pin (700μs default). It supports input damping for ≥24V sources and includes an EMI filter stage.
It features a fixed 3.3V output set by a 41.2kΩ/13kΩ resistor divider, power-good monitoring with ±10% window, and valley-current over-current protection with hiccup recovery. The board uses a 10μH XAL6060-103ME inductor and wettable-flank QFN-16 packaged IC for automotive-grade thermal and solder-joint reliability.

FAQ
Is EV4430-L-00A still in production?
No. The EV4430-L-00A is officially end-of-life per MPS documentation, and users are directed to migrate to the updated EVQ4430-L-00A evaluation board. Aetrix Electronics maintains limited legacy stock for design continuity and repair support only.
What IC does EV4430-L-00A evaluate?
The board evaluates the MP/MPQ4430GL - a 36V, 3.5A synchronous step-down converter in QFN-16 (3mm×4mm) with wettable flanks, AEC-Q100 Grade-1 qualification, and integrated 90mΩ high-side and 40mΩ low-side MOSFETs.
Can I adjust the output voltage on this board?
Yes. The output is set by an external resistor divider (RFB1/RFB2). The default 41.2kΩ/13kΩ network yields 3.3V, but values can be changed per the formula VOUT = 0.8V × (1 + RFB1/RFB2) to achieve other common outputs like 1.8V, 2.5V, 5V, or 12V.
How do I configure forced CCM vs. AAM mode?
Drive the SYNC pin high before startup to enable forced continuous conduction mode (CCM); leave it floating or pull low to activate Advanced Asynchronous Modulation (AAM) for higher light-load efficiency. No external clock is required for AAM operation.
Does the board include input EMI filtering?
Yes. It integrates a two-stage input EMC filter: CIN1–CIN6 (10μF ceramic bank) plus L1 and R5 for damping, specifically recommended when using long cables (>0.5m) or input voltages ≥24V to suppress ringing and conducted emissions.
What is the purpose of the "Golden Pin" test points?
The board includes five 2.0mm-pitch golden-pin test points for VIN/VEMI/GND/VOUT/GND and five 1.0mm-pitch golden-pin test points for EN/GND/SYNC/GND/PG - enabling non-invasive probing of critical signals without soldering or wire attachment.
