The ADP1032 is a high performance, isolated micropower management unit (PMU) that combines an isolated flyback and a dc-to-dc regulator providing two isolated power rails. Additionally, the ADP1032 contains four high speed serial peripheral interface (SPI) isolation channels and three general-purpose isolators for channel to channel applications where low power dissipation and small solution size is required. Operating over an input voltage range of 4.5 V to 60 V, the ADP1032 generates isolated output voltages of 6 V to 28 V (adjustable version) or 24 V (fixed version) for VOUT1, and factory programmable voltages of 5.15 V, 5.0 V, or 3.3 V for VOUT2

By default, the ADP1032 flyback regulator operates at a 250 kHz switching frequency, and the buck regulator operates at 125 kHz. 

The two regulators are phase shifted relative to each other to reduce electromagnetic interference (EMI). The ADP1032 can be driven by an external oscillator in the range of 350 kHz to 750 kHz to ease noise filtering in sensitive applications. 

The digital isolators integrated in the ADP1032 use Analog Devices, Inc., iCoupler® chip scale transformer technology, optimized for low power and low radiated emissions. The ADP1032 is available in a 9 mm × 7 mm, 41-lead LFCSP and is rated for a −40°C to +125°C operating junction temperature range.

AD-SWIOT1L-SL

Software-configurable Analog and Digital I/O with 10BASE-T1L Evaluation and Development Platform

Software-configurable Analog and Digital I/O with 10BASE-T1L Evaluation and Development Platform

Features and Benefits

  • Allows prototyping of intelligent, secure, and connected process control devices
  • Ultimate flexibility in I/O interface configurability through software
  • Embedded processing for implementing self-capable edge devices
  • Long-range single-pair 10BASE-T1L Ethernet interface
  • Power delivery via the 10BASE-T1L interface or from a field supply enabling both low and high power applications
  • Fully isolated design for safe operation
  • Industry standard form factor compatible with DIN rail mounts

Product Detail

The AD-SWIOT1L-SL provides a complete software and hardware platform for prototyping intelligent, secure, network capable field devices.

The design incorporates the AD74413R Quad-Channel, Software Configurable Input and Output and the MAX14906 Quad-Channel Industrial Digital Output/Digital Input ICs, allowing the multiplexing of several analog and digital functions on four channels which can be independently configurable through software to act as:

  • voltage output / input
  • current output / input
  • digital input / output
  • RTD measurement

A 10 Mbps single-pair Ethernet link, using the ADIN1110 10BASE-T1L MAC/PHY, enables remote data acquisition and device configuration. The 10BASE-T1L interface can also be used for powering the system via the Single-pair Power over Ethernet (SPoE) technology using the LTC9111 Powered Device (PD) controller. This way, power and data for the system is provided over the same cable to significantly simplify the cabling infrastructure and cost.

For applications requiring high current capabilities, the system can be powered from an external 24 V supply and up to 1.2 A can be output on any of the channels configured as digital outputs. The power supply solution also includes the ADP1032 high performance, isolated micropower management unit (PMU) to provide power and digital control for software configurable I/O devices in one of the most compact formats. The LT8304 Micropower No-Opto Isolated Flyback Converter completes the power tree to provide isolated power to the digital part of the design.

The on-board MAX32650 Ultralow Power ARM® Cortex®-M4 Microcontroller exposes all the necessary debug and programming features to enable a complete software development experience with the system. It is coupled with a 1 Gb (128 MB) external RAM and a 64 Mb (8 MB) external flash memory to meet the most demanding applications and provide the flexibility to implement any protocol stack. Security features are enabled by the MAXQ1065 security coprocessor.

The system is accompanied by an open-source software stack and associated collateral, enabling a complete experience from evaluation and prototyping all the way to production firmware and applications development. An external programmer such as the MAX32625PICO MAXDAP Programming Adapter, or any other similar programmer supporting the SWD interface, is required to enable firmware programming and debug. The system’s firmware is based on Analog Devices’ open-source no-OS framework which includes all the tools required for embedded code development and debugging as well as libraries enabling host-side connectivity for system configuration and data transfer over the UART or the 10BASE-T1L interfaces. A PC application with a user-friendly graphical interface is provided to enable easy system configuration and displaying the acquired data in different ways.

Product Detail

The ADP1032CP-x-EVALZ (where x represents the device model number of 1 through 5) can be used to demonstrate the functionality of the ADP1032 dc-to-dc converters and the isolated data channels.

Simple device measurements, such as line regulation, load regulation, and efficiency can be evaluated with the board. The performance of the isolated digital channels can also be evaluated. Device features, including oscillator synchronization, soft start, power good monitoring, sequencing and slew rate control may be demonstrated.

For more details about the dc-to-dc converters and the isolated data channels, refer to the ADP1032 data sheet.
