The ISL78264EVAL1Z evaluation board is used to evaluate the two-channel synchronous buck converter operation of the ISL78264 dual buck controller in which the converters have a 180° phase shift to minimize input capacitor stress. The board demonstrates the high efficiency of synchronous buck operation and all the features of the ISL78264 IC including overcurrent protection, overvoltage, and under-voltage protection, and power-good indication for each channel.
