  class ProductCollection extends \Magento\Framework\View\Element\Template
  {    
      protected $_productCollectionFactory;    
      public function __construct(
          \Magento\Backend\Block\Template\Context $context,        
          \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory                             $productCollectionFactory,        
          array $data = []
      )
      {    
          $this->_productCollectionFactory = $productCollectionFactory;    
          parent::__construct($context, $data);
      }
  
      public function getProductCollection()
      {
          $collection = $this->_productCollectionFactory->create();
          $collection->addAttributeToSelect('*');
          $collection->setPageSize(3); // fetching only 3 products
          return $collection;

• Show product collection in PHTML file

foreach ($productCollection as $product) {
    print_r($product->getData());
