Evaluation boards, like the STEVAL-ILL069V2, are essential to creating reliable and efficient devices. The STEVAL-ILL069V2 is a low-power off-line LED driver with a SMPS (Switched Mode Power Supply) for DC/DC and AC/DC applications. It is an easy and cost-effective way to evaluate the performance of such a power supply for your device.

The STEVAL-ILL069V2 is composed of several components which are connected in series. It consists of a power-supply portion, a current regulator and the LED load. All of these components work together in order to provide an efficient and safe electrical current to the connected device.

Starting off with the power-supply portion, this is where the power from the electrical grid is connected. It can provide current up to 350mA and voltage up to 36V. It is composed of two parts, the rectifier and the transformer. The rectifier takes the AC voltage and converts it to DC in order to be used by the rest of the device. The transformer is used to step down the voltage to the appropriate level for the device.

After the current is converted from alternating to direct, it is sent to the regulator. This component is responsible for regulating the current to the required voltage through the LED load. The regulator will then turn the LED on and off in order to maintain the desired voltage. This is known as Pulse Width Modulation (PWM).

The LED load is composed of an LED string connected in series along with a shunt regulator. The shunt regulator is used to protect the LED from any surges in current and to keep the voltage within an acceptable range. The LED can also be adjusted through the LED controller, which can be used to set the desired brightness level.

All of these components come together to ensure that the current supplied to the device is always safe and efficient. The STEVAL-ILL069V2 is an excellent tool for assessing the performance of a power supply for DC/DC and AC/DC applications. With it, you can easily and cost-effectively evaluate the power efficiency and safety of your device.
