id=\"Efficiency\"><\/span><strong>Eficiencia<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>This is one of the most obvious differences between the two.<\/p>\n<p>Linear Power Supply When the gap between Input Voltage and Output Voltage is large, Efficiency will decrease significantly.<\/p>\n<p>Switching Power Supply can usually provide higher Efficiency, so it is more suitable for Long-Term Continuous Operation.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Heat_generation\"><\/span><strong>Generaci\u00f3n de calor<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Linear Technology will produce more Thermal Loss, so a larger Heat Sink is usually required.<\/p>\n<p>Switching Technology Usually Produces Less Heat Because Of Higher Efficiency.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Size_and_Weight\"><\/span><strong>Tama\u00f1o y peso<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Traditional Linear Power Supply usually requires larger Transformers and Heat Sinks.<\/p>\n<p>In contrast, Switching Power Supply can use a higher
