Analog Devices Inc./Maxim Integrated MAX17692BEVKIT#

Overview

The MAX17692BEVKIT# from Maxim Integrated is an evaluation kit designed to validate the performance of the MAX17692B no-opto isolated flyback converter IC in 5V/0.65A isolated power supply applications. It implements a fully assembled, tested circuit with a 12-pin TDFN-packaged MAX17692BATC+ IC, 145kHz switching frequency, primary-side regulation, and ±5% output voltage accuracy across 18V–36V input and –40°C to +125°C.

For engineers reviewing the MAX17692BEVKIT# datasheet, MAX17692BEVKIT# pinout, MAX17692BEVKIT# application, or MAX17692BEVKIT# equivalent, this page provides verified operating conditions, efficiency curves, load transient response, PCB layout guidance, jumper configuration details (JU1/JU2), and component-level BOM sourcing - all critical for rapid prototyping of isolated industrial and medical DC-DC supplies.

Technical Context

The MAX17692BEVKIT# implements the MAX17692B's novel primary-side sampling architecture to regulate an isolated +5V output without an optocoupler or secondary-side feedback network. It uses a custom EP7 transformer (10348-T080 or 750319211) with 3:1:1.5 turns ratio and integrates a 76V nMOSFET to minimize external components.

Operation relies on resistor-programmable EN/UVLO (via R2/R3), external loop compensation (COMP pin), soft-start (CSS = 68nF), and optional SYNC/DITHER functionality (JU1 configurable). Output regulation is maintained within ±5% over line (18–36V), load (1mA–650mA), and temperature (–40°C to +125°C).

FAQ

What is the primary function of the MAX17692BEVKIT#?

The MAX17692BEVKIT# is a fully assembled evaluation kit that demonstrates and validates the operation of the MAX17692B no-opto isolated flyback converter IC. It delivers a regulated +5V/0.65A isolated output from an 18V–36V input using primary-side sensing-eliminating the need for an optocoupler. The MAX17692BEVKIT# includes all necessary passive components, transformer, and jumpers (JU1/JU2) for configuration and testing.

Does the MAX17692BEVKIT# require an external optocoupler for feedback?

No, the MAX17692BEVKIT# does not require an external optocoupler. It leverages the MAX17692B's proprietary primary-side sampling technique to sense and regulate the isolated +5V output directly from the primary winding. This eliminates optocoupler aging, bandwidth limitations, and secondary-side feedback component count - a core feature validated by the MAX17692BEVKIT# design.

What input voltage range and output load capability does the MAX17692BEVKIT# support?

The MAX17692BEVKIT# operates across a 18V to 36V DC input range and delivers up to 0.65A continuous output current at +5V. Output voltage remains within ±5% tolerance under full line, load (1mA–650mA), and temperature (–40°C to +125°C) variations - as confirmed in the EV kit performance report and schematic documentation.

How is enable/UVLO configured on the MAX17692BEVKIT#?

Enable and UVLO are configured via jumper JU2 on the MAX17692BEVKIT#. With shunt installed across pins 1–2, the EN/UVLO pin connects to VIN for immediate enable. With no shunt, the pin connects to the center node of R2 (280kΩ) and R3 (0Ω), allowing resistor-divider programming of the UVLO threshold - a flexible setup verified in the MAX17692BEVKIT# Quick Start guide and Table 2.

Can the MAX17692BEVKIT# be synchronized to an external clock?

Yes, the MAX17692BEVKIT# supports external clock synchronization and frequency dithering via the SYNC/DITHER pin (U1 Pin 10). Jumper JU1 controls this function: shunt across pins 1–2 disables it (connects to GND); removing the shunt allows connection to an external clock source - enabling EMI reduction and system-level timing coordination as documented in Table 1 and the MAX17692BEVKIT# schematic.
