Integrated 4A Switch PWM Step-Up Regulator Evaluation Board

The ISL97656IRTZEVALZ is an evaluation kit for the ISL97656 step-up voltage regulator that operates with high frequency and high efficiency. This evaluation kit is designed to deliver up to 2A output current for portable equipment and TFT-LCD displays. A dip switch that allows users to select either 620kHz or 1.2MHz frequency is provided in the kit.

The ISL97656 is a high-frequency, high-efficiency step-up voltage regulator operated at constant frequency PWM mode. With an internal 4.0A, 120mΩ MOSFET, it can deliver up to 2A of output current at over 90% efficiency. The selectable 640kHz and 1.2MHz allow smaller inductors and faster transient response. An external compensation pin gives the user greater flexibility in setting frequency compensation allowing the use of low ESR ceramic output capacitors.
