Analog Devices Inc./Maxim Integrated MAX17559EVKIT#

Overview

MAX17559EVKIT# from Maxim Integrated is an evaluation kit for the MAX17559 dual-output synchronous step-down controller, designed to validate 4.5V–60V input, 0.8V–24V dual-rail power designs with 100kHz–2.2MHz programmable switching frequency and 180° out-of-phase operation. It supports R_SENSE or DCR current sensing, independent soft-start/stop, and PWM/DCM mode selection - enabling rapid prototyping of industrial DC power systems.

For engineers reviewing the MAX17559EVKIT# datasheet, MAX17559EVKIT# setup guide, MAX17559EVKIT# test procedures, or MAX17559EVKIT# component compatibility, this kit provides fully assembled, tested hardware with documented schematics, BOM, layout files, and lab-measured performance data - accelerating validation of dual-output buck controller implementations in motion control, PLCs, and CNC systems.

Technical Context

The MAX17559EVKIT# implements the MAX17559 IC in a functional reference design using external nMOSFETs, bootstrap circuitry, and dual-loop compensation networks. It replicates the IC's peak-current-mode control architecture, 180° phase-shifted dual-channel timing, and independent EN_/PGOOD_/SS_ signal routing - allowing full characterization of startup into prebiased outputs, load transient response (e.g., 0→15A in 400µs), and overcurrent protection behavior under short-circuit conditions.

It validates critical system-level behaviors including VCCINT LDO sourcing from IN or VCCEXT (4.85V–24V), DH_/DL_ gate drive timing with <15ns falling edge, and ILIMSEL-configurable foldback vs. latchoff current limiting - all operating across the full –40°C to +125°C junction temperature range per the IC's specification.

FAQ

What is the primary function of the MAX17559EVKIT#?

The MAX17559EVKIT# is a fully assembled evaluation kit for the MAX17559 dual-output synchronous step-down controller. It enables engineers to validate 4.5V–60V input, dual-rail (0.8V–24V) power supply designs with features including 180° out-of-phase operation, programmable 100kHz–2.2MHz switching frequency, and independent PWM/DCM mode selection - directly supporting industrial power system development.

Does the MAX17559EVKIT# include the MAX17559 IC?

Yes, the MAX17559EVKIT# includes one pre-mounted MAX17559 IC in a 32-pin TQFP package. The board integrates all necessary support components - including gate drivers, bootstrap circuitry, feedback dividers, soft-start capacitors, and PGOOD pull-ups - allowing immediate bench testing without additional component sourcing.

Can the MAX17559EVKIT# demonstrate startup into a prebiased output?

Yes, the MAX17559EVKIT# fully supports monotonic startup into prebiased outputs - a key capability confirmed in the MAX17559 datasheet (Figure toc09). This behavior is enabled by the IC's SS_ pin architecture and verified on the kit via oscilloscope measurements of VOUT1/VOUT2 rise under zero-load, precharged conditions.

What current sensing methods does the MAX17559EVKIT# support?

The MAX17559EVKIT# supports both external current-sense resistors (R_SENSE) and inductor DCR sensing, as implemented in the MAX17559 IC. The board provides dedicated CS₊/CS₋ connections for each channel and includes jumpers to select sensing method - matching the IC's ±100mV input range and 13.3V/V gain specification.

Is thermal performance validated on the MAX17559EVKIT#?

Yes, the MAX17559EVKIT# layout follows Maxim's thermal guidelines, including exposed pad soldering to PGND and multilayer copper pours. Lab testing confirms operation up to +125°C ambient with thermal shutdown activation at +160°C junction temperature - consistent with the MAX17559 IC's specified θ_JA = 48°C/W and thermal shutdown threshold.
