The STEVAL-ISA178V1 evaluation board is a highly versatile DC/DC & AC/DC (off-line) SMPS (switched-mode power supply) designed to provide multiple output voltages. The STEVAL-ISA178V1 is ideal for applications such as mobile phones, LED lighting, wireless charging, automotive power, IoT, and many others. Taking advantage of the flexibility provided by the integrated isolated DC/DC & DC/AC, this evaluation board supports a wide variety of input voltage levels, from 3.3V, 6V and 12V to 24V. It also provides two independent outputs with adjustable output voltages and up to 2A of output current.

The STEVAL-ISA178V1 consists of two main integrated components, a controller and an isolated DC/DC & DC/AC. The controller is responsible for regulating the output and is based on the MC33269 MCU. It provides the necessary control functions to regulate the output voltage and current, as well as additional features such as overvoltage, overcurrent, and temperature protection. This module is also designed to operate over a wide input voltage range.

The isolated DC/DC & DC/AC component is based on the STGIPN 3SP2 device. This feature integrated circuit (IC) is designed to provide a high performance isolated DC/DC & DC/AC conversion with high efficiency levels and high power density. The STGIPN 3SP2 IC integrates a synchronous buck PWM controller, an MOSFET driver, an isolated opto-coupled feedback circuit, and a high-voltage power switch. This allows for the creation of a highly efficient power supply system with a wide range of input voltage and output voltage.

The STEVAL-ISA178V1 evaluation board also provides a variety of features designed to make it easier to set up, configure, and use. This includes a comprehensive graphical user interface (GUI) for system configuration, a programming adapter for programming of the MC33269 MCU, and a real time measurement for tuning of the power supply output. The evaluation board also includes a support library for the development of firmware for the MC33269 MCU, as well as a dedicated evaluation program for data logging and analysis.

In summary, the STEVAL-ISA178V1 evaluation board is a highly versatile and powerful DC/DC & AC/DC (off-line) SMPS designed to provide multiple output voltages to a wide range of applications. Taking advantage of the flexibility provided by the integrated isolated DC/DC & DC/AC and various other features, the STEVAL-ISA178V1 is ideal for a wide range of applications and a great starting point for anyone looking for a reliable, efficient, and easy-to-use power supply system.
