The STEVAL-ISA027V1 is an evaluation board designed by STMicroelectronics for DC/DC and AC/DC (Off-Line) SMPS. It is part of a series of evaluation boards for different Power supply applications.
The STEVAL-ISA027V1 is a 13W, 19V DC/DC and AC/DC (Off-Line) SMPS that is configurable to provide multiple output voltages such as 12V, 5V, 3.3V, and 1.5V. It is based on the STMicroelectronics ISL8117x device, which can be used as either an AC/DC (Off-Line) or DC/DC converter. The board supports both of these architectures and can provide several different output voltages with very accurate regulation.
The application field of the STEVAL-ISA027V1 covers a wide variety of power supply applications due to its ability to provide multiple output voltages and high precision. These applications include high-end computing, telecommunication, consumer electronics, industrial control, and embedded applications.
The STEVAL-ISA027V1 uses a fixed frequency, current-mode architecture to provide stable and accurate output voltage regulation. It is based on the STMicroelectronics ISL8117x device, which is a full integrated 700V off line switcher IC. It features a wide input voltage range of 8V-25V and is capable of producing multiple adjustable output voltages (12V, 5V, 3.3V, 1.5V). It also features high efficiency, low stand-by power consumption, and low EMI.
The STEVAL-ISA027V1 includes an on-board current sensing circuit. This circuit and associated circuitry provide protection from current overloads and voltage overshoots. It also has an external power supply shutdown input and an enable control input. This control input can be used to control the switching frequency or to shut down the power supply.
The board also includes a graphical user interface, which provides an easy way to configure the power supply parameters such as load type, output voltage range, and output current capacity. It also includes a range of test points, which allow further testing and debugging of the power supply.
The STEVAL-ISA027V1 is well suited for use in applications that require multiple adjustable outputs with high accuracy and efficiency. It is an ideal solution for embedded systems, industrial control, and communication devices. Its integrative power stage and current sensing circuit reduce total component cost and reduce design complexity, making it one of the most cost-effective solutions available for DC/DC and AC/DC (Off-Line) SMPS applications.
