The ISL8022EVAL1Z is a complete evaluation board designed to evaluate the performance of ISL8022 Integrated Power Supply controllers in off-line, DC/DC and AC/DC Switch Mode Power Supply (SMPS) applications. It is an ideal tool for quickly evaluating the performance of ISL8022 controller in a wide range of SMPS applications, such as AC-DC power supplies for consumer electronics, computing, industrial systems, end-equipment; DC-DC converters and LED lighting applications.

The ISL8022EVAL1Z board is designed and equipped with two input voltage capability (AC/DC and DC/DC), two output voltage setting and output power load. The input voltage can be set up to AC (90Vac – 265Vac) or DC (12V – 160V). The AC/DC input is connected to a power transformer while the DC/DC input is connected to a 16V to 160V line. Two independent voltage levels (12V and 3.3V) can be selected for the output. The board is equipped with an integrated heatsink which helps dissipate power dissipation. Furthermore, the board is also equipped with an adjustable output voltage trimming capability of +/- 10%, an output power indicator, and a load board.

The ISL8022EVAL1Z board brings a lot of advantages to the users. It offers excellent efficiency, improved output current capabilities, adjustable output current from 5mA to 200mA, and adjustable output voltage range from 2.5V to 20V. The board is also compatible with different power topologies, such as valley-clamp, buck, flyback, isolated converter, half-bridge and bridge converters. Moreover, the board also provides added protection against reverse current, OVP, OCP and overload functions.

The ISL8022EVAL1Z board is based on the ISL8022 Integrated Power Controller, with a proprietary configurable firmware. The controller also integrates various power and protection functions, thus eliminating the need of additional protection circuitry. The ISL8022EVAL1Z board is an easy to use and economical evaluation solution for SMPS applications, with adjustable output voltage and power levels.

The ISL8022EVAL1Z includes a configurable onboard Synchronous Rectifier (SR) and voltage regulator. The SR improves the Conversion Efficiency (C.E) of the SMPS power conversion stage by up to 12%. The voltage regulator allows fine-tuning of the output voltage setting accuracy up to 1V resolving power and +/- 0.5% absolute accuracy. The board also includes an embedded on-board Voltage Transformer, which enables the user to adjust the output voltage with the desired level.

The way the board works is quite simple. Once the power source and load are connected, the board will automatically detect the current level and voltage level of the output. The board will accordingly adjust its operating parameters to ensure the current remains constant and voltage is kept within the specified range. Furthermore, the board can be easily adjusted to meet different SMPS application needs by setting the appropriate power and voltage levels.

In conclusion, the ISL8022EVAL1Z is an ideal evaluation solution for SMPS applications. It offers excellent efficiency with adjustable output voltage and current, adjustable output voltage trimming and power indicator. It enables users to quickly evaluate the controller performance and optimize the power and protection functions for a variety of SMPS applications.
