Analog Devices Inc./Maxim Integrated MAX17692AEVKIT#

Overview

The MAX17692AEVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to validate the performance of the MAX17692A no-opto isolated flyback converter IC. It delivers a regulated +5V/0.65A isolated output from an 18V–36V input, operates at 145kHz, achieves up to 87% peak efficiency, and eliminates optocouplers via primary-side sensing.

For engineers reviewing the MAX17692AEVKIT# datasheet, MAX17692AEVKIT# setup procedure, MAX17692AEVKIT# input voltage range, or MAX17692AEVKIT# load regulation performance, this EV kit provides a production-ready reference design with documented transient response, efficiency curves, output ripple data, and jumper-configurable protection thresholds.

Technical Context

The MAX17692AEVKIT# implements the MAX17692A IC in a fixed 5V-output flyback topology using a custom EP7 transformer (10348-T080 or 750319211) and primary-side voltage sampling. It supports external clock synchronization and frequency dithering via the SYNC/DITHER pin, and enables resistor-programmable input UVLO and overvoltage protection through jumpers JU2 and JU3.

Regulation accuracy is ±5% across line (18V–36V), load (1mA–650mA), and temperature (−40°C to +125°C). Soft-start time is fixed at 15ms, and internal loop compensation minimizes external components-only 12 passive parts are active in the default configuration.

FAQ

What is the purpose of the MAX17692AEVKIT#?

The MAX17692AEVKIT# is a ready-to-use evaluation kit that demonstrates the MAX17692A no-opto flyback controller in a functional 5V/0.65A isolated power supply. It enables engineers to verify regulation accuracy, efficiency, transient response, and protection features without designing a custom PCB - all measurements and test procedures are documented in the official data sheet.

Does the MAX17692AEVKIT# require an optocoupler?

No, the MAX17692AEVKIT# does not use an optocoupler. It relies on the MAX17692A's proprietary primary-side sensing technique to regulate the isolated 5V output, eliminating the need for secondary-side feedback components and simplifying certification for reinforced isolation standards.

How is input undervoltage lockout (UVLO) configured on the MAX17692AEVKIT#?

UVLO is resistor-programmable via jumper JU2. With shunt installed across pins 1–2, the EN/UVLO pin connects directly to VIN, enabling the device immediately. With no shunt, UVLO threshold is set by the R2/R3 divider (280kΩ/11.8kΩ), yielding ~27.5V turn-on per the MAX17692A datasheet - verified in the MAX17692AEVKIT# schematic and Table 2.

Can the MAX17692AEVKIT# be synchronized to an external clock?

Yes, the MAX17692AEVKIT# supports external clock synchronization and frequency dithering via the SYNC/DITHER pin (U1 Pin 12). Installing no shunt on jumper JU1 leaves the pin open for connection to an external clock source - a capability confirmed in Table 1 and used in noise-sensitive applications per the data sheet.

What load and input conditions were used to characterize efficiency on the MAX17692AEVKIT#?

Efficiency was measured per the EV kit performance report (toc01) at three input voltages - 18V, 24V, and 36V - with load current swept from 0 to 650mA. Peak efficiency of 87% occurs at VIN = 24V, VOUT = 5V, IOUT = 0.65A, and is traceable to the published graph and test setup instructions in the MAX17692AEVKIT# data sheet.
