Analog Devices Inc./Maxim Integrated MAX15106CEVKIT#

Overview

MAX15106CEVKIT# from Analog Devices is an evaluation kit designed to validate the MAX15106C 6A synchronous step-down regulator with integrated switches in WLP20 package, preset for 1.5V output at up to 6A load from 2.7V–5.5V input, featuring 1.1MHz fixed switching frequency and all-ceramic capacitor design for fast transient response in portable power applications.

For engineers reviewing the MAX15106CEVKIT# datasheet, MAX15106CEVKIT# pinout, MAX15106CEVKIT# application, or MAX15106CEVKIT# equivalent, this page delivers verified hardware configuration, jumper-controlled enable/power-good behavior, soft-start timing via C16, output voltage adjustability (0.6V to 0.94×VIN), and proven PCB layout for rapid prototyping of high-current DC-DC conversion stages.

Technical Context

The MAX15106CEVKIT# implements a current-mode control architecture using the MAX15106C IC in WLP20 package, operating at a fixed 1.1MHz switching frequency to minimize output ripple and support compact ceramic output capacitance. It integrates high- and low-side MOSFETs and supports forced PWM mode across its full output range.

Hardware-level features include a shunt-configurable EN input (JU1), PGND-referenced PGOOD output, adjustable soft-start via external C16 (default 0.033µF → ~2ms), and resistor-divider-based VOUT tuning (R1/R2) with mandatory compensation reconfiguration (C14/R3/C15) per design requirements.

FAQ

What is the primary function of the MAX15106CEVKIT#?

The MAX15106CEVKIT# is a fully assembled and tested evaluation platform for the MAX15106C 6A synchronous step-down regulator. It provides immediate validation of electrical performance-including 1.5V/6A output, 1.1MHz operation, and all-ceramic filtering-using a proven PCB layout optimized for thermal and EMI performance. The MAX15106CEVKIT# requires no soldering or configuration to operate out of the box.

How does the MAX15106CEVKIT# differ from the MAX15106AEVKIT# and MAX15106BEVKIT#?

The MAX15106CEVKIT# is specifically configured for the MAX15106C variant, which operates at a fixed 1.1MHz switching frequency. In contrast, MAX15106AEVKIT# runs at 0.9MHz and MAX15106BEVKIT# at 1.0MHz. All three kits share identical board layout, component selection, and functionality except for the preinstalled MAX15106x IC and corresponding frequency-setting internal circuitry-no user-modifiable differences exist between them.

Can the output voltage of the MAX15106CEVKIT# be adjusted, and how?

Yes, the MAX15106CEVKIT# output voltage can be adjusted from 0.6V to 0.94×VIN by replacing resistors R1 and R2 in the feedback divider network. With default R1 = 8.06kΩ and R2 = 5.36kΩ, the output is set to 1.5V. To change VOUT, select R2 (1kΩ–20kΩ), then calculate R1 using R1 = R2 × ((VOUT / 0.6V) − 1). Compensation components (C14, R3, C15) must also be updated per the MAX15106 IC datasheet to maintain loop stability.

What role does jumper JU1 serve on the MAX15106CEVKIT#?

Jumper JU1 controls the enable state of the MAX15106C regulator on the MAX15106CEVKIT#. When installed, it connects the EN pin to the input rail (IN), enabling the device. When removed, R4 pulls EN to PGND, disabling the output. This hardware-level enable/disable toggle allows safe power sequencing without external logic and is documented in Table 1 of the MAX15106 Evaluation Kit user guide.

Does the MAX15106CEVKIT# support soft-start adjustment, and if so, how is it implemented?

Yes, the MAX15106CEVKIT# supports programmable soft-start via capacitor C16 connected between the SS pin and GND. With the default 0.033µF capacitor, soft-start time is approximately 2ms. To adjust, use C16 = (10µA × tSS) / 0.6V, where tSS is the desired soft-start duration in seconds. An external tracking reference can also be applied to SS for synchronized startup in multi-rail systems, as specified in the MAX15106 IC datasheet.
