DC\/DC converter for automotive technology with E13 approval. Galvanically isolated Li-Ion DC\/DC battery charging converter with extended input voltage range from 12V to 32V. The output voltage is 57VDC and is preset. Thanks to the ON control signal, this DC\/DC converter is also compatible with the D+ control signal.<\/p>\n","protected":false},"excerpt":{"rendered":"
The 729-57-ON by Demke Electronic is a galvanically isolated DC\/DC buck-boost converter for a nominal input voltage of 24 VDC. It operates across an input voltage range of 12 to 32 VDC and delivers 57 VDC at up to 8.40 A, equivalent to 450 W of output power. Efficiency reaches up to95% at nominal input voltage and full load.<\/p>\n","protected":false},"featured_media":8584,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[82],"product_tag":[],"product_application":[168,158,112,111,156,154,97,148,170,162],"product_standard":[146,140,138,144,126,130,136,132,122,120,118,124,128,134,142,172],"class_list":["post-8583","product","type-product","status-publish","has-post-thumbnail","product_cat-isolated-dc-dc-buck-boost-converters","first","instock","shipping-taxable","product-type-simple"],"acf":{"vin_min":12,"vin_max":32,"vin_nom":24,"vin_peak":35,"efficiency_max":95,"vout":57,"iout":8.4,"pout":450,"output_configuration":"single","em_filter":"input_output","switching_frequency":120,"max_capacitive_load":"infinite","shutdown_voltage_min":0,"shutdown_voltage_max":0,"enable_voltage_min":10.5,"enable_voltage_max":32,"switch_high_voltage_min":0,"switch_high_voltage_max":0,"mounting":"wall","connection_type":"Kabel","plug_pin_diameter":"","cable_lengths":"750 mm","produktstatus":"bto","temp_min":-40,"temp_max":85,"thermal_shutdown_temp":90,"ip_rating":"","mtbf":1000000,"technical_features":["cc_cv","parallel","no_load_short_circuit","emi_input_output","no_derating","input_low_ripple_noise","wide_input"],"remote_control":false,"isolation_type":"galv_isolated","potting":false,"certifications":["e13","reach","rohs","ce"],"datasheet_de":"https:\/\/demke-electronic.com\/wp-content\/uploads\/729.006_DB.pdf","datasheet_en":"https:\/\/demke-electronic.com\/wp-content\/uploads\/729.006_DB_EN.pdf","drawing":"https:\/\/demke-electronic.com\/wp-content\/uploads\/729.006_TZ.pdf","safety_instructions":"https:\/\/demke-electronic.com\/wp-content\/uploads\/729.006_SI.pdf","step":"","download_base":"729.006","step_model":"size_130x130x28","pim_id":"237979000000157707","web_visible":true,"sync_status":"success","last_sync":"2026-09-01 10:49:55","successor_sku":"","alternative_skus":"","h1_de":"729-57-ON | Galvanically isolated DC\/DC buck-boost converter 24 VDC to 57 VDC, 450 W","h1_en":"729-57-ON | Galvanically isolated DC\/DC buck-boost converter 24 VDC to 57 VDC, 450 W"},"_links":{"self":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product\/8583","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\/8584"}],"wp:attachment":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/media?parent=8583"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_brand?post=8583"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_cat?post=8583"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_tag?post=8583"},{"taxonomy":"product_application","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_application?post=8583"},{"taxonomy":"product_standard","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_standard?post=8583"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
