Analog Devices Inc./Maxim Integrated MAX17524EVKITE#

Overview

MAX17524EVKITE# from Maxim Integrated is an evaluation kit designed to validate the MAX17524 dual-output synchronous step-down DC-DC converter, delivering fixed 3.3V and 5V outputs at up to 3A per channel from a 6.5V–60V input. It operates at 450kHz, features adjustable UVLO, soft-start, external clock synchronization, and open-drain RESET signals, and serves as a reference design for high-voltage industrial power supplies.

For engineers reviewing the MAX17524EVKITE# datasheet, MAX17524EVKITE# pinout, MAX17524EVKITE# application, or MAX17524EVKITE# equivalent, this kit provides verified thermal layout, CISPR22 Class B EMI compliance, dual-channel mode selection (PWM/PFM/DCM), and proven PCB implementation for high-efficiency, high-input-voltage buck conversion.

Technical Context

The MAX17524EVKITE# implements the MAX17524 IC in a fully assembled, tested configuration with fixed 3.3V/5V outputs, 450kHz switching frequency, and independent EN/UVLO, MODE/SYNC, SS, and RESET pins for each channel. Input supply for Channel 2 can be derived from Channel 1 (via RIN1) or isolated via VIN2.

It integrates overcurrent and overtemperature protection, supports external clock synchronization on both channels, and includes configurable jumpers (JU1–JU5, JU3) for mode selection, UVLO threshold setting, and EXTVCC2 connection-enabling evaluation of efficiency trade-offs across PWM, PFM, and DCM modes under real load conditions.

FAQ

What is the primary function of the MAX17524EVKITE#?

The MAX17524EVKITE# is a fully assembled evaluation kit for the MAX17524 dual-output synchronous step-down DC-DC converter. It delivers fixed 3.3V and 5V outputs at up to 3A per channel from a 6.5V–60V input, enabling rapid validation of efficiency, regulation, transient response, and EMI performance without custom PCB design. The MAX17524EVKITE# includes all necessary components, jumpers, and layout optimizations for immediate bench testing.

Does the MAX17524EVKITE# support external clock synchronization?

Yes, the MAX17524EVKITE# provides dedicated MODE/SYNC1 and MODE/SYNC2 test points and jumpers (JU1 and JU2) to synchronize each channel to an external clock signal. When external clocks are applied and jumpers JU1/JU2 are left open, both MAX17524 channels operate in PWM mode only. This capability allows precise timing alignment in multi-converter systems and noise spectrum shaping for EMI reduction - a key feature confirmed in the MAX17524EVKITE# schematic and quick-start guide.

How is the input undervoltage lockout (UVLO) configured on the MAX17524EVKITE#?

The MAX17524EVKITE# uses jumpers JU4 (for Channel 1) and JU5 (for Channel 2) to configure EN/UVLO behavior. With pins 1–2 shorted (default), each channel enables at ~6.5V. To set a custom UVLO threshold, remove the shunt and connect a resistor divider (RTOP = 3.32MΩ max, RBOT calculated per datasheet equation) between VIN and SGND, feeding the center node to the respective EN/UVLO pin. This configuration is explicitly documented in Tables 1 and 2 of the MAX17524EVKITE# user guide.

Can the MAX17524EVKITE# evaluate both PWM and PFM operation modes?

Yes, the MAX17524EVKITE# supports full-mode evaluation: jumper JU1 selects PWM (pins 1–2), PFM (no shunt), or DCM (pins 2–3) for Channel 1; JU2 provides identical control for Channel 2. Performance plots in the MAX17524EVKITE# report show distinct efficiency vs. load curves for PWM, PFM, and DCM across both 3.3V and 5V outputs - confirming validated operation in all three modes under real-world conditions.

Is the MAX17524EVKITE# compliant with EMI standards?

Yes, the MAX17524EVKITE# meets CISPR22 Class B conducted and radiated emissions limits, as verified in its performance report (Figure toc37). Its PCB layout incorporates optimized power routing, ground plane integrity, and designated EMI filter footprints (L3, C6, C8); when populated, these reduce input noise injection and suppress radiated emissions - making the MAX17524EVKITE# a benchmark for EMI-aware buck converter design.
