ISL8117ADEMO1Z is a high performance, dual-mode power supply evaluation board that is used for DC/DC and AC/DC (off-line) SMPS applications. The ISL8117ADEMO1Z evaluation board is designed to provide an easy-to-use platform to evaluate the ISL8117A, a high-performance, dual-mode switching controller that combines a wide 4.25V to 54V input voltage range, excellent load and line regulation and a powerful 32-bit ARM Cortex-M0 microcontroller (MCU).

The ISL8117ADEMO1Z is a great tool for evaluating high power DC/DC and AC/DC (off-line) SMPS applications. It has been designed with features that enable it to efficiently control a wide range of off-line charging systems such as battery chargers, industrial power supplies, motor controllers, automotive systems, laptop adapters, and more. It offers high efficiency and low power consumption in a cost effective evaluation board.

The ISL8117ADEMO1Z evaluation board is comprised of a number of components that are connected to the ISL8117A controller. On the board are three independent converter channels (e.g. buck, boost and flyback), of which the two buck channels each allow for one output voltage level. The voltage levels for the buck channels are adjustable with a simple potentiometer. Additionally, the board provides the capability to design with an enhanced input voltage range of up to 54 V due to an external resistor divider.

The off-line SMPS application field of the ISL8117ADEMO1Z evaluation board facilitates output voltage levels ranging from 1.5V to 25V with efficiency of up to 92%. The ISL8117ADEMO1Z also supports a wide range of peak current and switching speeds (up to 4.5A peak current capability and up to 500KHz). The board also features two onboard current shunts for closed loop control.

The ISL8117ADEMO1Z evaluation board works on the principle of a Power Factor Corrected Switched Mode Power Supply, which is essentially a type of power supply that uses a switching device to deliver power from a source to a load in a controlled manner. This process allows for fast conversion of electricity from AC to DC while also improving power factor and efficiency. This evaluation board allows engineers to experiment and observe the performance of the ISL8117A when used in higher power off-line/DC-DC applications.

The ISL8117ADEMO1Z evaluation board provides a flexible platform for engineers to easily evaluate and design high power off-line SMPS applications. Through its featuresthe ISL8117A provides key benefits like a wide 4.25V to 54V input voltage range, exceptional load and line regulation, along with a powerful 32-bit ARM Cortex-M0 microcontroller. The evaluation board contains all the necessary components to enable designers to prototype for efficient and cost-effective high power off-line/DC-DC SMPS applications.
