Analog Devices Inc./Maxim Integrated MAX16923EVKIT#

Overview

MAX16923EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to validate the MAX16923 automotive 4-output display-power solution, featuring a 4.5V–36V input range, 2.1A high-voltage buck converter (5V/3.3V), 100mA low-I_Q HV LDO (3.3V), 1.6A LV buck (1.1V–3.3V), and 180mA LV LDO (1.1V–3.3V), used in TFT display power systems for ADAS and infotainment head units.

For engineers reviewing the MAX16923EVKIT# datasheet, MAX16923EVKIT# pinout, MAX16923EVKIT# application, or MAX16923EVKIT# equivalent, this kit enables rapid validation of startup sequencing, power-good signaling, watchdog timer behavior, spread-spectrum EMI reduction, and CISPR25 Class 5 compliance in automotive display power architectures.

Technical Context

The MAX16923EVKIT# implements the full reference design for the MAX16923GTPA IC, including all critical passive components, jumper-configurable switching frequencies (400kHz/440kHz/2MHz/2.2MHz), selectable digital-domain voltage sources (LDO1 or EXT_DVDD), and START/WAKE/FIN control logic via solder-jumpers J8–J10.

Hardware features include proven PCB layout with dedicated test points (TP_HV_BUCK, TP_LDO1, TP_LV_BUCK, etc.), automotive-grade ceramic and aluminum-electrolytic capacitors, shielded inductors (L1–L4), discrete MOSFETs (Q1–Q6) for external PMOS gate drive, and green LEDs (DS1–DS4, DS6) indicating rail status - all compliant with AEC-Q200 stress requirements per Maxim's design guidance.

FAQ

What does the MAX16923EVKIT# evaluate?

The MAX16923EVKIT# evaluates the MAX16923GTPA and MAX16926GTPA automotive power-management ICs. It provides a complete, functional reference design with all necessary passives, jumpers for configuration, test points, and LED indicators - enabling immediate validation of power sequencing, rail stability, power-good assertion timing, and watchdog reset behavior without custom PCB development.

Does the MAX16923EVKIT# support both MAX16923 and MAX16926 devices?

Yes, the MAX16923EVKIT# is explicitly designed to evaluate both the MAX16923 and MAX16926 ICs. The board accommodates either device in the U1 socket (TQFN-20 EP footprint), and documentation confirms identical hardware compatibility, jumper configurations, and test point access for both variants' shared feature set and pinout.

How is switching frequency configured on the MAX16923EVKIT#?

Switching frequency on the MAX16923EVKIT# is selected using jumpers J11–J16: J11 sets HV buck to 400kHz and LV buck to 2MHz; J12 sets HV buck to 440kHz and LV buck to 2.2MHz; J13–J16 provide additional combinations including watchdog enable/disable. Only one jumper may be installed at a time per Table 3 in the user guide.

What power-good signals are accessible on the MAX16923EVKIT#?

The MAX16923EVKIT# exposes three open-drain power-good signals: PG1 (HV buck), PGB (LV buck), and PGOOD (combined system good). These are pulled up to the digital-domain voltage (selectable via J3 between LDO1 or EXT_DVDD) and routed to test pads (PG1, PGB, PGOOD), enabling oscilloscope monitoring of startup timing and fault response.

Is the MAX16923EVKIT# compliant with automotive EMI standards?

Yes, the MAX16923EVKIT# is designed and verified to meet CISPR25 Class 5 radiated emissions limits when operated with spread-spectrum enabled and proper grounding. Its layout follows Maxim's automotive EMI guidelines, including shielded inductors, optimized ground planes, and controlled trace routing - making it suitable for pre-compliance EMI validation in display power designs.
