Analog Devices Inc./Maxim Integrated MAXM17505EVKIT#

Overview

MAXM17505EVKIT# from Maxim Integrated is an evaluation kit designed to demonstrate and validate the MAXM17505 Himalaya step-down power module-a fully integrated 4.5V–60V input, 0.9V–12V adjustable output, 1.7A DC-DC power module with integrated inductor, controller, dual MOSFETs, and compensation. It enables rapid prototyping of point-of-load regulators for FPGA, DSP, and industrial embedded systems.

For engineers reviewing the MAXM17505EVKIT# datasheet, MAXM17505EVKIT# pinout, MAXM17505EVKIT# application, or MAXM17505EVKIT# equivalent, this kit provides verified thermal performance, CISPR22 Class B emission compliance, startup/line/load transient characterization, and full configuration flexibility via MODE, RT, SS, SYNC, and FB pins-critical for validating power integrity in space-constrained industrial designs.

Technical Context

The MAXM17505EVKIT# implements the MAXM17505 SiP in a 29-pin 9mm × 15mm × 2.8mm thermally enhanced package with exposed pads (EP1/EP2/EP3) tied to SGND, LX, and OUT respectively. It supports three control modes-PWM (MODE = SGND), PFM (MODE = open), and DCM (MODE = VCC)-with externally programmable switching frequency (100kHz–1.8MHz via RT resistor) and soft-start timing (via SS capacitor).

Board-level features include pre-populated input/output capacitors per Table 1 (e.g., 2×2.2µF 1206 ceramic CIN, 1×47µF 1210 COUT for 5V output), dedicated test points for IN, OUT, FB, EN, SYNC, and RESET, and layout-optimized high-current paths for PGND/OUT/LX. The kit delivers ≤20mVpp output ripple at 1.7A and meets conducted/radiated EMI limits per CISPR22 Class B without additional filtering.

FAQ

What is the primary purpose of the MAXM17505EVKIT#?

The MAXM17505EVKIT# is an evaluation kit for the MAXM17505 power module, providing a fully assembled, tested PCB with input/output filtering, test points, and configuration jumpers to validate electrical performance, thermal behavior, and EMI compliance before integrating the MAXM17505 into end equipment.

Does the MAXM17505EVKIT# support synchronization to an external clock?

Yes, the MAXM17505EVKIT# exposes the SYNC pin of the MAXM17505 device, enabling synchronization of the switching frequency to an external clock source within 1.1× to 1.4× the internal fSW-critical for noise-sensitive systems like data converters or RF subsystems where switching harmonics must be controlled.

Can the MAXM17505EVKIT# be used to evaluate light-load efficiency?

Yes, the MAXM17505EVKIT# supports PFM mode (MODE pin left open), delivering <125µA quiescent current and >80% efficiency at 10mA load for 5V output-validated in typical operating characteristics plots (e.g., toc03, toc05). This makes it suitable for battery-backed or always-on industrial sensors.

What thermal data is provided with the MAXM17505EVKIT#?

The MAXM17505EVKIT# documentation includes ambient temperature vs. output current derating curves (toc43), junction-to-ambient thermal resistance (θJA = 30.8°C/W), and thermal shutdown/hysteresis (+165°C threshold, 10°C hysteresis), all measured using the actual evaluation board layout and copper area defined in land pattern 90-0459.

Is the MAXM17505EVKIT# compliant with EMC standards?

Yes, the MAXM17505EVKIT# achieves CISPR22 Class B conducted and radiated emissions compliance as documented in the MAXM17505 datasheet (Figure toc45), using the specified capacitor configuration (C7 = 220pF, C17/C18 = 150pF, C4/C14 open, L1 shorted) on the MAXM17505EVKITAE# variant referenced in test reports.
