To meet the increasing demands for isolated Power over Ethernet (PoE) power solutions, Maxim’s power supply experts have developed innovative, isolated, PoE, powered device (PD) power solutions. These isolated PoE power solutions efficiently convert high voltage PoE power into 5V and 12V outputs, respectively. Each design was tested for load and line regulation, as well as efficiency and transient performance. These boards feature a module architecture, with through-hole pins for immediate board placement and accelerated prototyping.
The MAX15038 is a synchronous buck converter which delivers up to 4A load current at output voltages from 0.6V to 90% of VIN. The integrated circuit (IC) supports the input voltage from 2.9V to 5.5V. The total output error is less than ±1% overload, line, and temperature ranges
Advanced factory automation solutions (i.e., Industry 4.0) require an increasing number of smart sensors, which are typically controlled using IO-Link point-to-point serial communication between the sensor and controller (master). As a leading provider of IO-Link sensor transceiver and master transceiver ICs, Maxim Integrated® also provides complete reference design solutions to help our customers improve their time to market. These proven designs cover all of the hardware and software requirements needed for compliance with the IO-Link standard.
Maxim Integrated partnered with First Sensor to design a reference design featuring the First Sensor 4-channel APD array, Maxim quad TIA with multiplexer MAX40662, and Maxim single fast comparator MAX40026.

Flyback converters are the preferred topology in the SMPS (switched-mode power supply) for medium- and low-power range applications because they are simple and economic. They have less components and are efficient in isolating the output from input. They are used in battery-powered applications, universal AC/DC converters, and industrial and telecommunication equipment. Isolated converters traditionally regulate the output voltage and current by utilizing a secondary side regulation (SSR) composed of an optocoupler and secondary error amplifier.
The MAXREFDES1252 is a No-Opto Flyback converter that delivers up to 1.2A at 14.5V from a 18V to 54V supply voltage. It is designed for industrial equipment that needs isolated voltage from wide input supply voltage.
The MAXREFDES1269 demonstrates how to build a DC-DC buck converter using the MAX20098 step-down controller for 5V DC output applications from a 6V to 36V input. This reference design delivers up to 20A at 5V output. The design uses a six-layer board. Table above shows an overview of the design specification.
The MAXREFDES01261 is a reference design for the asset tracker application based on the Maxim® solution. This reference design is a power management platform for the asset tracker, which includes the MAX32660, MAX77840, MAX77640, and MAX77827. This design demonstrates a small-size, low-power, highly effective, highly accurate, and flexible power management system.
Flyback converters are the preferred topology in isolated converters for medium and low power range applications due to their simplicity and economic considerations. As flyback converters are isolated converters, the output voltage and the current are traditionally regulated by utilizing the secondary side regulation (SSR) composed of an optocoupler and a secondary-error amplifier.
