Analog Devices Inc./Maxim Integrated MAX15106AEVKIT#

Overview

MAX15106AEVKIT# from Analog Devices is an evaluation kit designed to validate the MAX15106A 6A synchronous step-down regulator in WLP20 package, operating from 2.7V–5.5V input and delivering a preset 1.5V output at up to 6A load current with 1MHz fixed switching frequency and all-ceramic capacitor design.

For engineers reviewing the MAX15106AEVKIT# datasheet, MAX15106AEVKIT# pinout, MAX15106AEVKIT# application, or MAX15106AEVKIT# equivalent, this board enables rapid functional validation of high-efficiency DC-DC conversion in space-constrained portable and distributed power systems requiring fast transient response and layout-proven stability.

Technical Context

The MAX15106AEVKIT# implements a fully assembled, tested hardware reference for the MAX15106A IC - a current-mode, fixed-frequency (1MHz) buck converter with integrated high- and low-side MOSFETs, 0.6V feedback reference, and programmable soft-start via external capacitor C16 (0.033µF default, ~2ms).

It supports output voltage adjustment from 0.6V to 0.94×VIN in forced PWM mode using resistor divider R1/R2, requires no aluminum electrolytic input capacitors in compact layouts, and includes EN/PGOOD interface signals routed to test points and jumper JU1 for enable control.

FAQ

What is the primary function of the MAX15106AEVKIT#?

The MAX15106AEVKIT# is a fully assembled evaluation platform for the MAX15106A 6A synchronous step-down regulator. It enables engineers to verify electrical performance-including output regulation, efficiency, thermal behavior, and transient response-under real-world load conditions without custom PCB development. The MAX15106AEVKIT# includes all necessary passive components, test points, and jumper-controlled enable logic to accelerate design-in of the MAX15106A IC.

Does the MAX15106AEVKIT# support adjustable output voltage?

Yes, the MAX15106AEVKIT# supports output voltage adjustment from 0.6V to 0.94×VIN in forced PWM mode by modifying the feedback resistor divider (R1 and R2). The default configuration delivers 1.5V using R1 = 8.06kΩ and R2 = 5.36kΩ. When changing R1/R2, compensation components C14, R3, and C15 must also be updated per the MAX15106 IC datasheet to maintain loop stability - the MAX15106AEVKIT# provides footprints and layout space for these adjustments.

How is the enable function implemented on the MAX15106AEVKIT#?

The MAX15106AEVKIT# implements regulator enable via shunt jumper JU1: when installed, EN is connected to IN and the MAX15106A operates normally; when removed, EN is pulled to PGND through R4 (100kΩ), disabling the output. This configuration allows simple, reliable on/off control without external logic. The EN signal is accessible at test point SU1, enabling integration into system-level power sequencing circuits during validation of the MAX15106AEVKIT#.

What input and output capacitors are used on the MAX15106AEVKIT#?

The MAX15106AEVKIT# uses an all-ceramic capacitor design: three 10µF X5R 0603 capacitors (C1, C2, C19) at the input; four 47µF X5R 1206 capacitors (C5, C7–C9) at the output; plus 0.1µF (C10, C23), 1.0µF (C20), and 2200pF (C6) ceramic decoupling caps. No electrolytic capacitors are required - the design leverages the 1MHz switching frequency and optimized layout to achieve stability and low ripple without bulk aluminum types, simplifying BOM and improving reliability for the MAX15106AEVKIT#.

Can the MAX15106AEVKIT# be used to evaluate other variants like MAX15106B or MAX15106C?

No - the MAX15106AEVKIT# is specifically configured for the MAX15106A variant, which operates at 1.0MHz. While the kit's schematic and layout are shared across the family, the MAX15106BEVKIT# and MAX15106CEVKIT# are distinct orderable part numbers with different factory-set switching frequencies (0.9MHz and 1.1MHz respectively). Using the MAX15106AEVKIT# to evaluate MAX15106B or MAX15106C would require verifying timing loop stability and potentially adjusting compensation, as frequency-dependent parameters such as inductor DCR sensing and loop gain are not interchangeable across variants.
