For engineers reviewing the MAX20058EVKIT# datasheet, MAX20058EVKIT# pinout, MAX20058EVKIT# application, or MAX20058EVKIT# equivalent, this page delivers verified hardware configuration details, supported IC operating modes, board-level thermal and layout validation, and direct reference to the MAX20058ATCA/VY+ controller IC's functional boundaries and automotive compliance evidence.

Technical Context

The MAX20058EVKIT# implements a fully assembled, tested reference design for the MAX20058 IC in its 12-pin side-wettable TDFN-EP (3mm × 3mm) package. It validates the IC's peak-current-mode architecture, internal compensation, and dual LDO (VCC/EXTVCC) power routing under real-world load transients and thermal stress.

Board-level features include preconfigured 5V/1A output (fSW = 400kHz, PFM mode, 1.6A current limit), integrated soft-start capacitor (12nF), feedback divider (R4 = 95.3kΩ, R5 = 18.2kΩ), and EXTVCC protection network (4.7Ω + 0.1µF). The kit enables rapid verification of EN/UVLO threshold setting, RESET timing (2.1ms delay), and thermal shutdown recovery (160°C trip, 20°C hysteresis).

FAQ

What is the primary function of the MAX20058EVKIT#?

The MAX20058EVKIT# is an evaluation kit for the MAX20058 automotive synchronous step-down DC-DC converter IC. It provides a fully assembled, tested PCB that demonstrates the IC's 60V input capability, 1A output, programmable frequency (200kHz–2.2MHz), PFM/PWM mode selection, and AEC-Q100-compliant thermal and sequencing behavior - enabling immediate lab validation without custom layout.

Does the MAX20058EVKIT# support adjustable output voltage?

Yes - the MAX20058EVKIT# is configured for 5V output but supports full output adjustment from 0.8V to 90%VIN via external feedback resistors. The board includes test points and footprint space for R4/R5 rework, and the MAX20058 IC itself uses a precision 0.8V FB reference (±1.5% over –40°C to +125°C), allowing accurate recalibration for target voltages like 3.3V or 12V using standard resistor-divider equations.

Can the MAX20058EVKIT# be used to validate thermal performance in automotive environments?

Yes - the MAX20058EVKIT# implements the IC's exposed-pad TDFN-EP package with thermal vias connected to large copper planes, directly validating junction-to-ambient thermal resistance (θJA = 41°C/W) and thermal shutdown behavior (160°C trip, 20°C hysteresis). It enables measurement of temperature rise under sustained 1A load across –40°C to +125°C ambient conditions per AEC-Q100 requirements.

What power sequencing features are demonstrated by the MAX20058EVKIT#?

The MAX20058EVKIT# demonstrates three key sequencing functions: (1) EN/UVLO threshold setting via a 105kΩ resistor to configure turn-on at ~12V, (2) open-drain RESET output with 2.1ms delay after regulation is achieved and 92% undervoltage detection, and (3) EXTVCC switchover logic (4.74V rising threshold) to improve efficiency at high VIN. All are wired and tested on the board per MAX20058 datasheet specifications.

Is the MAX20058EVKIT# compatible with external clock synchronization?

Yes - the MAX20058EVKIT# exposes the RT/SYNC pin with appropriate AC coupling and termination provisions, enabling external clock synchronization up to 2200kHz as specified in the MAX20058 datasheet. The onboard 105kΩ RT resistor sets nominal 400kHz operation, but removing it allows direct injection of a clean square-wave clock signal meeting the 1.15× to 1.4× fSW window and ≥40ns minimum off-time requirements.
