Analog Devices Inc./Maxim Integrated MAXM15462EVKIT#

Overview

MAXM15462EVKIT# from Maxim Integrated is an evaluation kit for the MAXM15462 adjustable-output Himalaya uSLIC™ step-down power module, supporting 0.9V–5V output at up to 300mA from a 4.5V–42V input. It features peak-current-mode control, 4.1ms soft-start, open-drain RESET, and PFM/PWM mode selection - designed for rapid validation of compact, high-efficiency DC-DC solutions in industrial sensor and battery-powered systems.

For engineers reviewing the MAXM15462EVKIT# datasheet, MAXM15462EVKIT# pinout, MAXM15462EVKIT# application, or MAXM15462EVKIT# equivalent, this kit enables immediate functional verification of the MAXM15462 module's adjustable regulation, prebias startup, hiccup overcurrent protection, and CISPR22 Class B EMI compliance without custom PCB design.

Technical Context

The MAXM15462EVKIT# implements the full reference circuit for the MAXM15462 module, including external feedback resistors (R3/R4), input/output capacitors (1µF CIN, 10µF COUT), and proper layout for thermal and EMI performance. It supports both enable-controlled and VIN-initiated startup, with visible waveforms for LX switching node, RESET assertion timing, and load transient response.

Designed for direct evaluation of the integrated uSLIC™ architecture, the kit validates key operational modes: PWM-only (MODE = GND), automatic PFM-to-PWM transition, and true shutdown via EN/UVLO threshold programming. All critical thermal, electrical, and safety margins - including -40°C to +125°C ambient operation and 166°C thermal shutdown - are accessible and measurable on-board.

FAQ

What is the primary function of the MAXM15462EVKIT#?

The MAXM15462EVKIT# is a fully assembled evaluation board that demonstrates and validates the operation of the MAXM15462 adjustable-output uSLIC™ power module. It provides all necessary passive components, test points, and layout optimized for thermal performance and EMI compliance - enabling immediate bench testing of output regulation, transient response, startup behavior, and protection features without custom hardware design.

Can the MAXM15462EVKIT# be used to evaluate MAXM15463 or MAXM15464 modules?

No - the MAXM15462EVKIT# is specifically configured for the MAXM15462 adjustable-output module. Its feedback resistor network (R3/R4) and default jumpers are set for 0.9V–5V output tuning. The MAXM15463 (fixed 3.3V) and MAXM15464 (fixed 5V) require different evaluation kits (e.g., MAXM15463EVKIT#, MAXM15464EVKIT#) with appropriate FB connections and component values to ensure accurate regulation and stability.

Does the MAXM15462EVKIT# support prebias startup?

Yes - the MAXM15462EVKIT# fully supports prebias startup functionality as implemented by the underlying MAXM15462 module. When enabled via the EN/UVLO pin, the kit allows the output capacitor to be precharged before VIN ramp-up, preventing reverse current flow and ensuring safe power sequencing in systems with back-driven rails.

How is the output voltage adjusted on the MAXM15462EVKIT#?

The output voltage on the MAXM15462EVKIT# is adjusted using the external resistor divider connected to the FB pin, per the MAXM15462's feedback architecture. The kit includes solder jumpers and pads to install user-selected R3 and R4 values (e.g., 133kΩ/75kΩ for 2.5V), with equations and layout guidance provided in the MAXM15462 datasheet to achieve precise 0.9V–5V output settings.

What thermal performance can be expected from the MAXM15462EVKIT# under full load?

At 300mA output and 24V input, the MAXM15462EVKIT# achieves junction temperatures ≤115°C in still air with its standard 4-layer PCB layout, well below the MAXM15462's 150°C absolute maximum. Derating curves in the datasheet confirm ≥250mA continuous output at +125°C ambient, validated using the kit's thermal test points and IR imaging.
