Analog Devices Inc./Maxim Integrated MAX17693AEVKIT#

Overview

MAX17693AEVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit for the MAX17693A no-opto isolated flyback converter IC, configured to deliver 5V/0.25A output from an 18V–36V input, operating at 150kHz with ±5% regulation and 88% peak efficiency.

For engineers reviewing the MAX17693AEVKIT# datasheet, MAX17693AEVKIT# pinout, MAX17693AEVKIT# application, or MAX17693AEVKIT# equivalent, this kit enables rapid validation of primary-side regulated isolated DC-DC conversion in industrial power supplies, medical auxiliary rails, and space-constrained IoT gateways requiring optocoupler-free design.

Technical Context

The MAX17693AEVKIT# implements the MAX17693A IC-a 76V nMOSFET-integrated flyback controller using proprietary primary-side sampling to eliminate optocouplers while maintaining tight ±5% output regulation across line (18V–36V), load (0–250mA), and temperature (−40°C to +125°C).

It supports resistor-programmable EN/UVLO and OVI protection, external clock synchronization via SYNC/DITHER pin, VCC overdrive for efficiency optimization, and internal loop compensation-reducing external component count and simplifying layout verification for production-ready designs.

FAQ

What is the primary function of the MAX17693AEVKIT#?

The MAX17693AEVKIT# is a ready-to-use evaluation platform for the MAX17693A no-opto flyback controller IC. It demonstrates isolated 5V/0.25A DC output generation from 18V–36V input using primary-side regulation-eliminating the need for optocouplers, TL431 references, or secondary-side feedback circuitry. The MAX17693AEVKIT# includes all critical passives, transformer, and jumpers pre-configured for default operation.

Does the MAX17693AEVKIT# require external components to operate?

No-the MAX17693AEVKIT# is fully assembled and tested, requiring only a 18V–36V DC power supply and optional resistive load for functional verification. Jumper settings (JU1–JU3) are pre-configured for default 5V operation; no additional components are needed to achieve ±5% output regulation, soft-start, or UVLO functionality. The MAX17693AEVKIT# includes proven PCB layout and thermal design per Maxim's reference implementation.

Can the MAX17693AEVKIT# be used to evaluate different output voltages?

Yes-the MAX17693AEVKIT# supports configurable output voltage via external resistor dividers on the FB pin, as defined in the MAX17693A datasheet. While factory-configured for 5V, users can modify R2/R3 values (accessible via JU2) and adjust transformer turns ratio to target other isolated outputs (e.g., 3.3V, 12V). The MAX17693AEVKIT# schematic and BOM provide full design flexibility for custom voltage derivations.

What protection features are implemented on the MAX17693AEVKIT#?

The MAX17693AEVKIT# implements resistor-programmable input under-voltage lockout (UVLO) and overvoltage protection (OVI) via jumpers JU2 and JU3, respectively. It also includes soft-start (20ms), thermal shutdown (via MAX17693A internal sensing), and primary-side overcurrent limiting. These protections are enabled by default and verified across −40°C to +125°C, ensuring robust operation of the MAX17693AEVKIT# in real-world industrial environments.

Is the MAX17693AEVKIT# RoHS compliant and production-ready?

Yes-the MAX17693AEVKIT# is RoHS-compliant (denoted by # suffix) and built using commercial-grade, multi-source passive components listed in its BOM (e.g., Murata, Vishay, Coilcraft). Its PCB layout, thermal design, and component selection follow Maxim's production guidelines. While intended for evaluation, the MAX17693AEVKIT# serves as a validated reference for direct migration into volume manufacturing of isolated auxiliary power supplies.
