Operating from a 2.8V to 60V input range, it supports multiple topologies including boost (up to 60V output), SEPIC (output above or below input), and inverting (negative output voltage). The 1.5 MHz maximum switching frequency minimizes inductor and capacitor size. Spread spectrum frequency modulation reduces EMI peaks, simplifying compliance with automotive and industrial EMC standards. Burst Mode operation maintains high efficiency at light loads with only 9 \u00b5A quiescent current, critical for battery-powered and always-on applications.","working_principle":"The LT8365EMSE operates as a current-mode DC-DC converter controller with an integrated 60V NPN power switch. In boost mode, the switch connects the inductor to ground during on-time, storing energy, then releases it to the output through an external Schottky diode during off-time. The current-mode control loop senses switch current for cycle-by-cycle current limiting and provides inherent input voltage feedforward for improved line transient response. In SEPIC mode, a coupling capacitor transfers energy between the input and output sides of the inductor, allowing the output to be above, below, or equal to the input voltage. In inverting mode, the output is referenced to ground with negative polarity. The spread spectrum modulation varies the switching frequency by \u00b120% around the center frequency, spreading EMI energy across a wider bandwidth and reducing peak emissions. Burst Mode operation skips switching cycles at light load, reducing switching losses while maintaining output regulation.","pin_description":"<table border=\"1\"><tr><th>Pin<\/th><th>Name<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>SW<\/td><td>Switch Pin (inductor connection)<\/td><\/tr><tr><td>2<\/td><td>SW<\/td><td>Switch Pin (inductor connection)<\/td><\/tr><tr><td>3<\/td><td>EN\/UVLO<\/td><td>Enable \/ Undervoltage Lockout Input<\/td><\/tr><tr><td>4<\/td><td>VC<\/td><td>Error Amplifier Compensation Output<\/td><\/tr><tr><td>5<\/td><td>FB<\/td><td>Feedback Voltage Input (1.0V reference)<\/td><\/tr><tr><td>6<\/td><td>RT\/SYNC<\/td><td>Frequency Set Resistor \/ External Sync Input<\/td><\/tr><tr><td>7<\/td><td>SS<\/td><td>Soft-Start Capacitor Input<\/td><\/tr><tr><td>8<\/td><td>PGOOD<\/td><td>Power Good Open-Drain Output<\/td><\/tr><tr><td>9<\/td><td>BST<\/td><td>Bootstrap Capacitor Connection<\/td><\/tr><tr><td>10<\/td><td>INTVCC<\/td><td>Internal 2.6V Regulator Bypass<\/td><\/tr><tr><td>11<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>12-13<\/td><td>GND<\/td><td>Ground (thermal)<\/td><\/tr><tr><td>14<\/td><td>SHDN<\/td><td>Shutdown Input (active low)<\/td><\/tr><tr><td>15<\/td><td>VIN<\/td><td>Input Supply (2.8-60V)<\/td><\/tr><tr><td>16<\/td><td>VIN<\/td><td>Input Supply (2.8-60V)<\/td><\/tr><\/table>","application_scenarios":"<ul><li><b>Automotive 48V Bus<\/b>: 48V to 12V SEPIC converter maintaining output during cold-crank (down to 2.8V) and load-dump (up to 60V) transients<\/li><li><b>4-20mA Loop Power<\/b>: 24V loop-powered SEPIC generating isolated 5V\/3.3V rails with 9 \u00b5A quiescent current for transmitter electronics<\/li><li><b>Telecom -48V<\/b>: Inverting topology generating +12V or +5V from -48V telecom bus with spread spectrum for NEBS EMI compliance<\/li><li><b>Industrial Sensor<\/b>: Wide input 12-48V to 5V boost converter powering industrial sensors with Burst Mode efficiency at light load<\/li><li><b>LED Driver<\/b>: Constant current boost topology for high-brightness LED strings from automotive 12V battery with analog dimming via VC pin<\/li><\/ul>","alternative_models":"<table border=\"1\"><tr><th>Model<\/th><th>Brand<\/th><th>Vin (V)<\/th><th>Isw (A)<\/th><th>Package<\/th><\/tr><tr><td>LT8362EMSE<\/td><td>ADI<\/td><td>2.8-60<\/td><td>2<\/td><td>MSOP-16<\/td><\/tr><tr><td>LT8361EMSE<\/td><td>ADI<\/td><td>2.8-60<\/td><td>1.5<\/td><td>MSOP-16<\/td><\/tr><tr><td>LM5175RHFR<\/td><td>TI<\/td><td>3.5-55<\/td><td>5 (ext)<\/td><td>VQFN-28<\/td><\/tr><tr><td>TPS55340RTE<\/td><td>TI<\/td><td>2.7-38<\/td><td>5.25<\/td><td>QFN-16<\/td><\/tr><tr><td>LTC3789EUH<\/td><td>ADI<\/td><td>4-38<\/td><td>10 (ext)<\/td><td>QFN-32<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/8485","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=8485"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/8485\/revisions"}],"predecessor-version":[{"id":8486,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/8485\/revisions\/8486"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=8485"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=8485"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=8485"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=8485"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
