The 105-3.3 is a classic non-isolated POL converter (3.3V Point of Load DC\/DC converter) and it is mostly used on “motherboards” with DC supply voltages of 5V, 12V or 24V to generate the local 3.3VDC. An astonishing high efficiency characterizes the DC\/DC converter in the Dil24 package even from 24V to 3.3V. The 3.3V output voltage can also be generated reliably with an input-side 5V supply voltage. Customer-specific adjustments in the output voltage down to 0.8V are possible at any time.<\/p>\n","protected":false},"excerpt":{"rendered":"
The 105-3.3 by Demke Electronic is a non-isolated DC\/DC step-down converter for a nominal input voltage of 24 VDC. It operates across an input voltage range of 6 to 36 VDC and delivers 3.30 VDC at up to 1.50 A, equivalent to 5 W of output power. Efficiency reaches up to95% at nominal input voltage and full load.<\/p>\n","protected":false},"featured_media":7978,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[81],"product_tag":[],"product_application":[111,97,102],"product_standard":[140,122,120,118,134,142],"class_list":["post-7977","product","type-product","status-publish","has-post-thumbnail","product_cat-dc-dc-abwaertswandler","first","instock","shipping-taxable","product-type-simple"],"acf":{"vin_min":6,"vin_max":36,"vin_nom":24,"vin_peak":38,"efficiency_max":95,"vout":3.3,"iout":1.5,"pout":5,"output_configuration":"single","em_filter":"input","switching_frequency":200,"max_capacitive_load":"6600","shutdown_voltage_min":0,"shutdown_voltage_max":0,"enable_voltage_min":0,"enable_voltage_max":0,"switch_high_voltage_min":0,"switch_high_voltage_max":0,"mounting":"pcb","connection_type":"L\u00f6tstifte","plug_pin_diameter":0.6,"cable_lengths":"","produktstatus":"bto","temp_min":-40,"temp_max":85,"thermal_shutdown_temp":110,"ip_rating":"","mtbf":1800000,"technical_features":["no_load_short_circuit","emi_input","no_derating","input_low_ripple","ultrawide_input"],"remote_control":false,"isolation_type":"non_isolated","potting":false,"certifications":["reach","rohs"],"datasheet_de":"https:\/\/demke-electronic.com\/wp-content\/uploads\/105.002_DB.pdf","datasheet_en":"https:\/\/demke-electronic.com\/wp-content\/uploads\/105.002_DB_EN.pdf","drawing":"https:\/\/demke-electronic.com\/wp-content\/uploads\/105.002_TZ.pdf","safety_instructions":"https:\/\/demke-electronic.com\/wp-content\/uploads\/105.002_SI.pdf","step":"","download_base":"105.002","step_model":false,"pim_id":"237979000000156019","web_visible":true,"sync_status":"success","last_sync":"2026-09-01 07:51:48","successor_sku":"","alternative_skus":"","h1_de":"105-3.3 | DC\/DC step-down converter 24 VDC to 3.30 VDC, 5 W","h1_en":"105-3.3 | DC\/DC step-down converter 24 VDC to 3.30 VDC, 5 W"},"_links":{"self":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product\/7977","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/media\/7978"}],"wp:attachment":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/media?parent=7977"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_brand?post=7977"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_cat?post=7977"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_tag?post=7977"},{"taxonomy":"product_application","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_application?post=7977"},{"taxonomy":"product_standard","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_standard?post=7977"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
