Analog Devices Inc./Maxim Integrated MAX16932EVKIT#

Overview

MAX16932EVKIT# from Analog Devices is an evaluation kit for the MAX16932 dual high-voltage synchronous step-down controller IC. It supports 3.5V–36V input, delivers independently regulated 5V and 3.3V outputs (or adjustable 1V–10V), operates up to 2.2MHz switching frequency, and achieves 20µA quiescent current in skip mode - enabling crank-ready automotive power designs with low-noise, phase-interleaved operation.

For engineers reviewing the MAX16932EVKIT# datasheet, MAX16932EVKIT# pinout, MAX16932EVKIT# application, or MAX16932EVKIT# equivalent, this kit provides validated reference design, thermal performance data, EMI-optimized layout, and full functional test coverage for the MAX16932 dual buck controller in automotive-grade AEC-Q100 environments.

Technical Context

The MAX16932EVKIT# implements the MAX16932 dual synchronous buck controller in a fully assembled, tested 28-pin TQFN-EP reference design. It validates 180° out-of-phase interleaving to reduce input ripple, spread-spectrum EMI reduction, and FSYNC-synchronized operation across 1.2–2.4MHz external clock range.

It demonstrates critical automotive features: -40°C to +125°C operation, BIAS LDO switchover via EXTVCC, PGOOD monitoring with 85–95% rising/falling thresholds, cycle-by-cycle current limiting, and thermal shutdown at +170°C - all verified under load dump, slow-VIN ramp, and short-circuit conditions.

FAQ

What is the primary purpose of the MAX16932EVKIT#?

The MAX16932EVKIT# is an evaluation kit for the MAX16932 dual synchronous buck controller IC. It provides a fully assembled, tested PCB with schematics, layout files, and test reports to validate performance - including 3.5V–36V input operation, 5V/3.3V dual outputs, 20µA quiescent current, and EMI-reduction features - before integrating the MAX16932 into automotive production designs.

Does the MAX16932EVKIT# support both MAX16932 and MAX16933 variants?

No - the MAX16932EVKIT# is specifically configured for the MAX16932 (2.2MHz switching frequency variant). The MAX16933 operates at 200kHz–1MHz and requires different compensation, inductor sizing, and layout considerations; it is not supported by this kit's default configuration or documentation.

Can the MAX16932EVKIT# be used to evaluate adjustable output voltages?

Yes - the MAX16932EVKIT# supports both fixed-output (5V/3.3V) and adjustable modes. Jumpers and feedback resistors allow reconfiguration for 1V–10V outputs on either channel, with validation of line/load regulation, soft-start timing (6ms typical), and PGOOD threshold accuracy per the MAX16932 datasheet specifications.

How does the MAX16932EVKIT# demonstrate EMI reduction capabilities?

The MAX16932EVKIT# validates three EMI mitigation techniques: 180° out-of-phase interleaving (reducing input ripple), ±6% spread-spectrum dithering (lowering peak spectral energy), and programmable 1–2.2MHz switching (avoiding AM band). Measured spectral energy density plots (TOC25–TOC27) confirm compliance in real-world automotive noise environments.

Is thermal performance data included with the MAX16932EVKIT#?

Yes - the MAX16932EVKIT# documentation includes validated thermal metrics: junction-to-ambient θJA = 35°C/W, junction-to-case θJC = 3°C/W, and thermal shutdown activation at +170°C with 20°C hysteresis. These values were measured on the actual kit board using JEDEC JESD51-7 methodology and are provided in the user guide.
