The STEVAL-ISA156V1 evaluation board is a power electronics solution for low power off-line applications like DIN rail and desktop adapters. It features an integrated boost and buck controller as well as a wide input voltage range with active PFC and delivers up to 25W. The board offers the ability for precise adjustable output voltage through external resistive dividers. It is specifically designed for applications including 12V, 24V industrial, automation and consumer applications.

The evaluation board is aimed at designers who need to build simple and compact power supplies. It provides a reliable and easy to use platform for the evaluation and testing of the STEVAL-ISA156V1 integrated circuit. The board includes all necessary circuitry for an efficient and safe evaluation session, like protection and EMC components, heat sink and fan for improved thermal performance.

The STEVAL-ISA156V1 evaluation board is based on the STEVAL-ISA156V1 IC of the TEFP family. This IC has two integrated controllers, one for buck and one for boost, with dual slope control that enable the buck/boost operations of the evaluation board. The integrated Active Power Factor Correction (PFC) allow the System to operate from a wide input voltage range (80-305VAC). The main feature of this evaluation board is the ability to adjust the output voltage to the exact value required. This can be achieved through external resistive dividers on the board.

The board can deliver up to 25W, and the standby power consumption is limited to 2W. The STEVAL-ISA156V1 evaluation board also offers several features for safety and reliability, such as Sleep and/or Totem Pole PFC on/off control, under voltage lockout and over voltage protection.

In terms of usage, the evaluation board supports several different measurements over the DC input and output, such as power, current, voltage, ripple and noise. Most importantly, it is also possible to modify the settings of the STEVAL-ISA156V1 IC. The board offers push buttons to control all of these operations such as ON, OFF, Sleep, Light Load Management and PFC/Standby functions. All of these various operational states can be monitored and monitored in real time on a display.

The STEVAL-ISA156V1 evaluation board is a powerful and reliable solution for low power off-line applications. It combines a wide input voltage range, integrated active PFC and adjustable output voltage, offering reliable and easy to use platform for the evaluation and testing of the STEVAL-ISA156V1 integrated circuit. Its ability to operate from a wide range of input voltages, offer protection features and precise adjustable output voltage make it suitable for a wide range of power circuitry designs.
