Analog Devices Inc./Maxim Integrated MAXM17624EVKITE#

Overview

MAXM17624EVKITE# from Analog Devices is an evaluation kit designed to validate the MAXM17624 1A, 4MHz, 3.3V-output uSLIC™ power module under real operating conditions. It supports PWM/PFM mode selection via jumper configuration, delivers up to 95.2% efficiency at 5V input/3.3V output/400mA load, and complies with CISPR32 Class B conducted and radiated emissions standards for industrial power design verification.

For engineers reviewing the MAXM17624EVKITE# datasheet, MAXM17624EVKITE# pinout, MAXM17624EVKITE# application, or MAXM17624EVKITE# equivalent, this kit enables rapid characterization of transient response, startup behavior into pre-bias, EMI performance, thermal derating, and PGOOD timing - all critical for compact, high-frequency DC-DC converter integration in space-constrained embedded systems.

Technical Context

The MAXM17624EVKITE# hosts a fully assembled and tested MAXM17624AMB+ module configured for fixed 3.3V output across 3.6V–5.5V input, with internal 1ms soft-start and PGOOD output pulled up to VIN. Its PCB layout implements low-inductance power paths, integrated EMI filtering (L201, C202, C203), and optional hot-plug damping (C204) to meet stringent EMC requirements without external redesign.

Two independent evaluation circuits - one for MAXM17623 and one for MAXM17624 - are electrically isolated on the same board. The MAXM17624 section uses R202/R203 (118kΩ/37.4kΩ) for FB voltage division, C208 (10μF/16V X7R) as output capacitor, and C205 (2.2μF/10V) as input capacitor, all optimized per the module's 4MHz switching frequency and current-sense architecture.

FAQ

What is the primary function of the MAXM17624EVKITE#?

The MAXM17624EVKITE# is a fully assembled evaluation kit that demonstrates and validates the performance of the MAXM17624 1A, 4MHz, 3.3V-output uSLIC™ power module. It provides measured data for efficiency, load transient response, startup/shutdown timing, PGOOD assertion, EMI compliance, and thermal derating - enabling engineers to verify system-level integration without custom PCB development. The MAXM17624EVKITE# includes jumpers for PWM/PFM mode selection and EN control, making it suitable for both steady-state and dynamic power analysis.

Does the MAXM17624EVKITE# support adjustable output voltage?

No, the MAXM17624EVKITE# is configured for a fixed 3.3V output using the onboard resistor divider (R202 = 118kΩ, R203 = 37.4kΩ). While the underlying MAXM17624AMB+ module supports adjustable outputs from 1.5V to 3.3V, the MAXM17624EVKITE# hardware implements only the 3.3V preset. To evaluate other voltages, users must modify the feedback resistors per the MAXM17624 data sheet - but the MAXM17624EVKITE# itself ships and operates exclusively at 3.3V.

How does the MAXM17624EVKITE# achieve CISPR32 Class B compliance?

The MAXM17624EVKITE# achieves CISPR32 Class B compliance through a combination of integrated EMI filter components (L201 = 0.68µH shielded inductor, C202 = 0.47µF, C203 = 2.2µF X7R ceramics), optimized high-frequency PCB layout with minimized loop areas, and strategic placement of input damping capacitors (C204 = 47µF tantalum). Radiated and conducted emission plots in the official data sheet confirm compliance across 30MHz–1GHz (radiated) and 150kHz–30MHz (conducted), eliminating need for external filtering during pre-compliance testing. The MAXM17624EVKITE# was measured per standard procedures with these components installed.

Can the MAXM17624EVKITE# be used to evaluate both MAXM17623 and MAXM17624 modules?

No - the MAXM17624EVKITE# is specifically configured for the MAXM17624 module only. Although the documentation references dual-module evaluation kits, the exact part number MAXM17624EVKITE# corresponds to the variant containing only the MAXM17624AMB+ (U201) circuit, with dedicated components including C208 (10µF/16V output cap), R202/R203 feedback network, and JU201/JU202 mode/enable jumpers. The MAXM17623 circuit is present on a separate board variant (MAXM17623EVKITE#); they are orderable as distinct SKUs and not interchangeable on the same PCB.

What load conditions were used to validate the 95.2% efficiency rating on the MAXM17624EVKITE#?

The 95.2% efficiency rating for the MAXM17624EVKITE# was measured under specific conditions: VIN = 5V, VOUT = 3.3V, IOUT = 400mA, at TA = +25°C, operating in PWM mode. This value appears in the official data sheet's Features section and is confirmed by the "MAXM17624 EFFICIENCY vs. LOAD CURRENT" plot (toc03), where peak efficiency occurs near mid-load. Efficiency drops to ~92% at 1A full load and ~85% at 10mA light load in PFM mode. All measurements were performed on the MAXM17624EVKITE# with its stock component set and default jumper settings.
