The STEVAL-ISA093V1 is a 230V AC/DC flyback LED driver, designed for SMPS (Switch Mode Power Supply) applications. It is an evaluation board manufactured by STMicroelectronics, which is available in standard DIP package options for low-power and cost-effective solutions. The board contains various components, including a DC/DC converter, an inductor, a valid current regulator and several LED drivers. The STEVAL-ISA093V1 is designed to offer optimal power delivery, high efficiency and improved reliability for products when used in a range of applications.

The STEVAL-ISA093V1 is designed to function as an electronic lighting system. This evaluation board allows for the configuration of different light sources, thanks to its four LED drivers. Each channel has its own selectable current threshold, enabling the board to be individually tuned and regulated. Dynamic AC/DC lighting control is possible through the adjustable LED driver inputs. This allows the light intensity to be managed, in order to create aesthetically pleasing lighting scenarios.

The STEVAL-ISA093V1 board works by drawing power from an AC mains source. The integrated switch mode power supply (SMPS) is responsible for converting the AC to a usable voltage and current, by way of a voltage rectifier bridge, power factor correction and an SMPS inductor. This then passes through the LED drivers and out to the light sources. The adjustable current setting on the LED drivers can be used to control the intensity of the light source.

The STEVAL-ISA093V1 has the ability to protect against energy surges, thanks to its integrated circuit (IC) overvoltage protection. This feature is designed to shut down the system in the event of an overvoltage, thus preventing damage to the light sources and system components. The board also features two temperature sensors. These are used to detect any changes in the system’s temperature, enabling the board to adjust the output level accordingly.

The STEVAL-ISA093V1 is a highly-reliable solution for SMPS applications. Its selection of components, such as the LED drivers, voltage rectifier bridge and overvoltage protection, make it an ideal choice for DC/DC and AC/DC applications. The adjustable LED driver inputs allow for dynamic lighting control, allowing for more creative lighting solutions. The board is designed to maximize efficiency and reduce energy consumption, making it an energy-saving and cost-effective solution.
