Analog Devices Inc./Maxim Integrated MAXM15068EVKIT#

Overview

MAXM15068EVKIT# from Maxim Integrated is an evaluation kit designed to validate the MAXM15068 high-voltage synchronous step-down DC-DC power module operating at 12V output, 200mA max load, 91.13% peak efficiency (VIN=24V), and 550kHz switching frequency in industrial power supply applications.

For engineers reviewing the MAXM15068EVKIT# datasheet, MAXM15068EVKIT# pinout, MAXM15068EVKIT# application, or MAXM15068EVKIT# equivalent, this page delivers verified performance data, jumper-configurable UVLO and PFM/PWM mode selection, RESET signal monitoring, CISPR22 Class B EMI compliance, and full assembly/test status - all critical for rapid prototyping of 15.5–60V input systems.

Technical Context

The MAXM15068EVKIT# implements a fully assembled, surface-mount reference design centered on the MAXM15068 micro-SLIC power module (10-pin, integrated MOSFETs, controller, and compensation). It supports resistor-programmable EN/UVLO threshold (e.g., 15.5V startup via R1=2.2MΩ/R2=191kΩ) and dual-mode operation selected via jumper J2 (PFM for light-load efficiency or PWM for fixed-frequency stability).

Board-level features include proven PCB layout with dedicated ground/power layers, optional EMI filter components (LEMI_1=82µH, CEMI_1=0.47µF, CEMI_2=1µF), hot-plug damping capacitor C2 (4.7µF/100V), and regulated VCC (5V) with 1µF bypass (C5). Output voltage ripple is measured at 10mVpp under full load (24V→12V, 200mA, PWM mode).

FAQ

What is the primary function of the MAXM15068EVKIT#?

The MAXM15068EVKIT# is a fully assembled evaluation kit that demonstrates and validates the performance of the MAXM15068 high-voltage synchronous step-down DC-DC power module. It delivers a fixed 12V output up to 200mA from a 15.5V–60V input, featuring programmable UVLO, PFM/PWM mode selection, RESET signaling, and CISPR22 Class B EMI compliance - enabling rapid power architecture prototyping without custom layout.

Does the MAXM15068EVKIT# support adjustable output voltage?

The MAXM15068EVKIT# is factory-configured for 12V output using R3=931kΩ and R4=75kΩ. However, the underlying MAXM15068 module supports adjustable output from 5V to 12V via external feedback resistors. To change output voltage, replace R3 and R4 per Table 1 in the MAXM15068 datasheet - the EVKIT# board includes pads and routing to support this modification without redesign.

How is undervoltage lockout (UVLO) configured on the MAXM15068EVKIT#?

UVLO on the MAXM15068EVKIT# is resistor-programmable via R1 (2.2MΩ) and R2 (191kΩ), setting a default startup threshold of 15.5V. Jumper J1 controls enable logic: open (default) enables operation above UVLO threshold; shorted pins 2–3 disables the module. The EN/UVLO pin connects to the center node of the R1–R2 divider, allowing precise threshold tuning by adjusting R2 value.

Can the MAXM15068EVKIT# operate in both PFM and PWM modes?

Yes - mode selection is controlled by jumper J2. With J2 uninstalled, the MAXM15068EVKIT# operates in PFM mode at light loads for improved efficiency; installing J2 across pins 1–2 forces constant-frequency PWM operation across all load conditions. Performance plots in the datasheet confirm >90% efficiency down to 1mA in PFM mode and tight regulation stability in PWM mode.

What EMI mitigation features are included on the MAXM15068EVKIT#?

The MAXM15068EVKIT# integrates multiple EMI-reduction elements: optional EMI filter (LEMI_1=82µH, CEMI_1=0.47µF, CEMI_2=1µF), optimized 4-layer PCB stackup with solid ground/power planes, strategic placement of high-frequency capacitors (C1/C4/C7), and damped input path using C2 (4.7µF/100V electrolytic). Radiated emission measurements show compliance with CISPR22 Class B limits under full-load conditions.
