Analog Devices Inc./Maxim Integrated MAX15062C5EVKITE#

Overview

The MAX15062C5EVKITE# from Maxim Integrated is a fully assembled and tested evaluation kit designed to demonstrate the performance of the MAX15062C 60V, 300mA synchronous step-down DC-DC converter in a fixed 5V output configuration. It operates from 6.5V to 60V input, delivers up to 300mA load current, switches at 500kHz, achieves 95% peak efficiency, and includes EN/UVLO control, hiccup-mode overcurrent protection, and open-drain RESET output - enabling rapid validation in industrial power supply and embedded system designs.

For engineers reviewing the MAX15062C5EVKITE# datasheet, MAX15062C5EVKITE# pinout (including JU1 jumper and RESET/EN/UVLO test points), MAX15062C5EVKITE# application (5V buck regulation under wide VIN), or MAX15062C5EVKITE# equivalent (evaluation kits for similar 60V/300mA buck ICs), this page provides verified board-level specifications, EMI-compliant layout details, mode-selection guidance (PWM vs. PFM), thermal and efficiency test data, and supplier-part traceability for production-grade prototyping.

Technical Context

The MAX15062C5EVKITE# implements the MAX15062C IC in a fixed 5V output configuration using internal compensation and a 47µH power inductor (L3). It supports dual operation modes: forced-PWM (default, via 0Ω R3) and PFM (for light-load efficiency), with programmable EN/UVLO threshold set by R1/R2 divider (6.4V nominal startup when JU1 open).

Board-level features include CISPR22 Class B-compliant conducted and radiated emissions performance, hot-plug support via optional 22µF/100V electrolytic capacitor (CIN4), and dedicated test points for VOUT, VIN, EN/UVLO, and RESET - all integrated into a compact PCB layout optimized for thermal dissipation and EMI suppression without external filtering components.

FAQ

What is the primary function of the MAX15062C5EVKITE#?

The MAX15062C5EVKITE# is a fully assembled evaluation kit that demonstrates the operation and performance of the MAX15062C synchronous step-down converter configured for a fixed 5V output. It enables engineers to validate voltage regulation, efficiency, transient response, and EMI behavior under real-world conditions - including input ranges from 6.5V to 60V and loads up to 300mA - without requiring custom PCB development. The MAX15062C5EVKITE# includes all necessary components, test points, and documented jumper configurations for immediate bench testing.

Does the MAX15062C5EVKITE# support adjustable output voltage?

No, the MAX15062C5EVKITE# is configured exclusively for a fixed 5V output using the MAX15062CATA+ IC and a preset feedback network. Output voltage is not user-adjustable on this board; it lacks external resistor dividers or trim-pot provisions for VOUT tuning. For variable-output evaluation, designers must refer to other MAX15062 evaluation platforms or implement custom feedback circuits - the MAX15062C5EVKITE# serves specifically as a turnkey solution for 5V system rail validation.

How is enable and undervoltage lockout controlled on the MAX15062C5EVKITE#?

Enable and undervoltage lockout (EN/UVLO) on the MAX15062C5EVKITE# are controlled via jumper JU1 and the onboard R1/R2 resistor divider. With JU1 open, the MAX15062C powers on when VIN exceeds ~6.4V; installing a shunt across pins 2–3 disables the device. The EN/UVLO test point allows external logic-level control, and the R1/R2 values (3.32MΩ and 787kΩ) set the precise UVLO threshold per the MAX15062 data sheet equation - all verified during MAX15062C5EVKITE# functional testing.

What are the key EMI design features of the MAX15062C5EVKITE#?

The MAX15062C5EVKITE# incorporates multiple EMI mitigation techniques: a compact, low-inductance PCB layout with optimized power loops; dedicated bottom-layer footprints for optional conducted EMI filter components (L1/C1); inclusion of CIN4 (22µF/100V electrolytic) to dampen hot-plug oscillations; and routing that suppresses radiated emissions - collectively enabling compliance with CISPR22 Class B limits for both conducted (0.15–30MHz) and radiated (30–1000MHz) emissions without external filters. These features are documented in the MAX15062C5EVKITE# performance reports.

Can the MAX15062C5EVKITE# operate in PFM mode, and how is it enabled?

Yes, the MAX15062C5EVKITE# supports both forced-PWM and PFM modes. By default, it operates in PWM mode with a 0Ω resistor installed at R3. To enable PFM mode - which improves light-load efficiency - remove the 0Ω resistor from R3, leaving the footprint open. This configuration change is validated in the MAX15062C5EVKITE# test procedures and reflected in the included efficiency vs. load plots (toc03 and toc01), confirming >85% efficiency down to 1mA load in PFM mode.
