Analog Devices Inc./Maxim Integrated MAX15158EVKIT#

Overview

MAX15158EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to validate the MAX15158, MAX15158A, and MAX15158Z high-voltage multiphase boost controllers in inverting-buck-boost configurations. It supports -8V to -60V input voltage, delivers 3.3V to 60V output voltage (default 35V), operates across -40°C to +125°C, and integrates two MAX15013 MOSFET drivers plus an onboard MAX17552 buck converter for 10V DRV supply.

For engineers reviewing the MAX15158EVKIT# datasheet, MAX15158EVKIT# pinout, MAX15158EVKIT# application, or MAX15158EVKIT# equivalent, this kit enables rapid functional validation of high-voltage inverting-buck-boost topologies, switching frequency configuration (480kHz–4MHz), output voltage adjustment via resistor divider, UVLO threshold tuning, and multi-kit synchronization for four-phase operation.

Technical Context

The MAX15158EVKIT# implements a proven six-layer PCB design hosting the MAX15158ATJ+ controller (T3255-6 package), two MAX15013 half-bridge drivers, and discrete power stage components including BSC110N15NS5 MOSFETs and SER2915H-103KL inductors. It supports both single-phase and dual-phase operation with configurable master/slave synchronization via jumpers J1–J11.

Hardware features include banana jacks for VIN+/VIN− and VOUT+/VOUT−, test points for EN/UVLO, FREQ/CLK, REFIN, COMP, SS, PGOOD, and BODE±, plus on-board 10Ω resistor for bode plot measurement. DRV supply can be sourced either from the onboard MAX17552 or externally (8V–12V).

FAQ

What is the default output voltage of the MAX15158EVKIT# and how is it adjusted?

The MAX15158EVKIT# is factory-set to deliver 35V output. This voltage is configured by the resistor divider between VOUT+ and OUTP pins. To adjust output voltage, replace the feedback resistors per the MAX15158 data sheet's VOUT calculation formula. Ensure compensation network values are updated accordingly to maintain loop stability across the new operating point. The MAX15158EVKIT# supports full 3.3V–60V range with appropriate component changes.

Does the MAX15158EVKIT# support dual-phase operation out of the box?

Yes, the MAX15158EVKIT# supports dual-phase operation natively using its onboard MAX15158ATJ+ controller and two MAX15013 drivers driving four BSC110N15NS5 MOSFETs. Phase interleaving is enabled by default; no hardware modification is required. For four-phase operation, two MAX15158EVKIT# units can be synchronized via jumpers J1–J11 as master/slave, per the EV kit user guide.

How is the UVLO threshold set on the MAX15158EVKIT# and what is its default value?

The UVLO threshold on the MAX15158EVKIT# is set by the R19/R20 resistor divider on the EN/UVLO pin and defaults to 21V. The threshold is calculated as VIN × (R20 / (R19 + R20)). To modify it, replace R19 or R20 with values satisfying the MAX15158's EN/UVLO specification. Note that the UVLO threshold must remain above the MAX17552 DRV supply's own UVLO to prevent premature shutdown.

Can the MAX15158EVKIT# be used with an external clock source, and what is the supported frequency range?

Yes, the MAX15158EVKIT# accepts an external clock signal applied to the FREQ/CLK test point (CLOCK). The supported range is 480kHz to 4MHz, matching the MAX15158 controller's specification. When using an external clock, remove the R16 pull-down resistor (41.2kΩ) connecting FREQ/CLK to VIN−. The external clock overrides internal oscillator operation and enables precise frequency synchronization across multiple converters.

What power supply requirements are needed to operate the MAX15158EVKIT# safely?

A single 60V DC power supply (PS1) is required, capable of delivering sufficient current for the selected output load. Input must be connected to VIN+ and VIN− banana jacks with correct polarity: positive terminal to VIN+, negative to VIN−. Caution: Power must not be applied until all connections-including shunts on J3/J4 and J6 pins 2–3-are verified. The board draws DRV supply from MAX17552 (10V) or external 8V–12V, but main input remains the sole high-voltage source.
