The controller pulses the switch on and off at a fixed frequency. During the &#8220;on&#8221; time, energy is stored in the inductor; during the &#8220;off&#8221; time, that energy is released to the output. By varying the ratio of on-time to total period \u2014 the duty cycle \u2014 the converter sets the output voltage.<\/p>\n<p>The key mechanical difference is <em>where<\/em> the switch and inductor sit relative to the load. In a buck stage the high-side switch is in series with the input and the inductor feeds the output, so the output is always below the input. In a boost stage the switch sits on the ground return and the inductor sits on the input side, so the output is always above the input. The output capacitor smooths the switched waveform into a steady DC rail, and the feedback loop continuously trims the duty cycle to hold the setpoint. WEHO&#8217;s enclosed DC-DC modules integrate this entire stage into a sealed, DIN-rail- or chassis-mount package rated for industrial environments, with a catalog spanning 1000+ models and full OEM\/ODM support.<\/p>\n<figure id=\"attachment_13797\" aria-describedby=\"caption-attachment-13797\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-13797\" title=\"WH C481260 1\" src=\"https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/04\/WH-C481260-1.png\" alt=\"WH C481260 1\" width=\"800\" height=\"800\" srcset=\"https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/04\/WH-C481260-1.png 800w, https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/04\/WH-C481260-1-300x300.png 300w, https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/04\/WH-C481260-1-500x500.png 500w, https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/04\/WH-C481260-1-768x768.png 768w, https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/04\/WH-C481260-1-12x12.png 12w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-13797\" class=\"wp-caption-text\">WH C481260 1<\/figcaption><\/figure>\n<h2><span class=\"ez-toc-section\" id=\"Buck_vs_Boost_Converter_Key_Differences\"><\/span>\u0e1a\u0e31\u0e4a\u0e01 VS Boost \u0e41\u0e1b\u0e25\u0e07: \u0e04\u0e27\u0e32\u0e21\u0e41\u0e15\u0e01\u0e15\u0e48\u0e32\u0e07\u0e17\u0e35\u0e48\u0e2a\u0e33\u0e04\u0e31\u0e0d<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Voltage_Direction\"><\/span>\u0e17\u0e34\u0e28\u0e17\u0e32\u0e07\u0e41\u0e23\u0e07\u0e14\u0e31\u0e19\u0e44\u0e1f\u0e1f\u0e49\u0e32<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A <strong>Buck \u0e41\u0e1b\u0e25\u0e07<\/strong> only steps down; a <strong>\u0e40\u0e1e\u0e34\u0e48\u0e21\u0e41\u0e1b\u0e25\u0e07<\/strong> only steps up.
