Analog Devices Inc./Maxim Integrated MAX15158ZEVKIT#

Overview

MAX15158ZEVKIT# from Maxim Integrated is an evaluation kit for the MAX15158Z high-voltage multiphase boost controller, enabling rapid prototyping of single/dual/quad-phase boost and inverting-buck-boost converters. It supports 8V–76V (boost) or –8V––76V (inverting) input, 3.3V–60V output, 120kHz–1MHz switching, and precise phase current sharing across up to four external MOSFETs - validated in telecom power supplies and industrial HVDC systems.

For engineers reviewing the MAX15158ZEVKIT# datasheet, MAX15158ZEVKIT# setup guide, MAX15158ZEVKIT# test procedure, or MAX15158ZEVKIT# compatibility with MAX15158Z controller ICs, this kit delivers fully assembled, tested hardware with documented layout, thermal performance data, and reference schematics for fast validation of high-efficiency, high-reliability DC-DC conversion in demanding 48V/54V bus applications.

Technical Context

The MAX15158ZEVKIT# implements the MAX15158Z controller in a dual-phase configuration using two external gate drivers and four discrete MOSFETs, with differential current sensing per phase via CSP/CSN inputs and active phase balancing via CSIOP/CSION synchronization. It incorporates the internal 4.74V BIAS LDO, REFIN-based dynamic output voltage programming (1V–2.2V), and RAMP-adjustable slope compensation.

It validates key protection features including adjustable EN/UVLO (0.9V rising), cycle-by-cycle peak current limit (20–100mV threshold), FB overvoltage fault (8.5–12% of target), and thermal shutdown at 165°C - all operating across –40°C to +125°C junction temperature with full 5mm × 5mm TQFN footprint replication.

FAQ

What is the primary function of the MAX15158ZEVKIT#?

The MAX15158ZEVKIT# is a fully assembled evaluation kit for the MAX15158Z high-voltage multiphase boost controller. It enables functional validation, efficiency measurement, and thermal characterization of dual-phase boost and inverting-buck-boost converter designs - including verification of phase current sharing, dynamic REFIN response, and fault protection behavior under real-world load transients.

Does the MAX15158ZEVKIT# support quad-phase operation?

Yes - the MAX15158ZEVKIT# is configured for dual-phase operation out-of-box but is designed to validate quad-phase stacking. Two MAX15158ZEVKIT# units (or one kit plus a second MAX15158Z controller board) can be synchronized via the SYNC pin and CSIO differential current-sense interface, as specified in the MAX15158Z datasheet for master/slave interleaving and current balance.

Can the MAX15158ZEVKIT# be used for inverting-buck-boost topologies?

Yes - the MAX15158ZEVKIT# supports inverting-buck-boost operation using the MAX15158Z's internal high-voltage feedback level shifter. The kit implements OUTP/OUTN differential sensing and validates proper startup sequencing, UVLO on OUTN (7.2V typ), and accurate regulation when VIN– is connected to system negative rail - confirmed in application circuits on page 14 of the MAX15158Z datasheet.

What protection features are validated on the MAX15158ZEVKIT#?

The MAX15158ZEVKIT# validates all key protections of the MAX15158Z IC: adjustable EN/UVLO (0.9V rising threshold), cycle-by-cycle peak current limit (20–100mV CSP–CSN threshold), fast positive/negative overcurrent detection, FB overvoltage fault (10% of target), thermal shutdown at 165°C, and PGOOD signaling - with oscilloscope waveforms and fault recovery timing documented in the user guide.

Is the MAX15158ZEVKIT# compatible with standard 48V telecom power architectures?

Yes - the MAX15158ZEVKIT# is explicitly validated for 48V input (8.5V–14V DRV supply derived from bias winding), delivering up to 60V output with >92% efficiency at 12V/35V outputs per typical curves. Its layout, thermal design, and component selection align with GR-1089-CORE and IEC 61000-4 immunity requirements for telecom infrastructure use cases.
