Unlike most boosts, the circuit disconnects the output to protect against shorts or other fault conditions when the input voltage exceeds the output. The input voltage range for normal operation is from 8V to 60V. OVLO becomes active for inputs above 63V and the maximum input voltage is 110V. The LED current is 400mA and the switching frequency is 250KHz. The efficiency is 92% when the input is 12V and the LED voltage is at 87V which is the maximum LED voltage. Spread spectrum switching is available to simplify ;conducted emissions compliance. There is a 6.8nF capacitor from the RAMP pin to ground to set the rate at which frequency modulation occurs, but resistor R20 shorting the RAMP pin capacitor must be removed to activate spread spectrum.\u003c\/p\u003e\n  \u003cul\u003e\n   \u003cli\u003e400mA LED current (ILED) at RS2 = 0.62ohm\u003c\/li\u003e\n   \u003cli\u003e4A input current limit at RS3 = 0.015ohm\u003c\/li\u003e\n   \u003cli\u003eDesigned to be easily reconfigured to buck mode, buck-boost mode and SEPIC topologies\u003c\/li\u003e\n   \u003cli\u003eDemo circuit uses ceramic input and output capacitors\u003c\/li\u003e\n  \u003c\/ul\u003e\n \u003c\/div\u003e\n\u003c\/div\u003e \u003ch4\u003eProduct details\u003c\/h4\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cdiv\u003e\n \u003cdiv\u003e\n  \u003cdiv\u003e\n   \u003cdiv\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eDevice Topology\u003c\/span\u003e\n     \u003cp\u003eBoost, Buck, Buck-Boost, SEPIC\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eOutput Current\u003c\/span\u003e\n     \u003cp\u003e10A\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eInput Voltage Min\u003c\/span\u003e\n     \u003cp\u003e4.5V\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eCore Chip\u003c\/span\u003e\n     \u003cp\u003eLT3795EFE\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eKit Contents\u003c\/span\u003e\n     \u003cp\u003eDemonstration Board LT3795EFE\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eSVHC\u003c\/span\u003e\n     \u003cp\u003eNo SVHC (21-Jan-2025)\u003c\/p\u003e\n    \u003c\/div\u003e\n   \u003c\/div\u003e\n   \u003cdiv\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eNo. of Outputs\u003c\/span\u003e\n     \u003cp\u003e1Outputs\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eOutput Voltage\u003c\/span\u003e\n     \u003cp\u003e110V\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eInput Voltage Max\u003c\/span\u003e\n     \u003cp\u003e110V\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eDimming Control Type\u003c\/span\u003e\n     \u003cp\u003eAnalogue, PWM\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eProduct Range\u003c\/span\u003e\n     \u003cp\u003e-\u003c\/p\u003e\n    \u003c\/div\u003e\n   \u003c\/div\u003e\n  \u003c\/div\u003e\n \u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch4\u003eOther details\u003c\/h4\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eANALOG DEVICES\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eDC1827A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003eEach\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTechnical Data Sheet EN\u003c\/td\u003e\n\u003ctd\u003e\u003ca href=\"http:\/\/www.farnell.com\/datasheets\/4473460.pdf\" target=\"_blank\" title=\"View or Download\" download\u003e\u003cimg src=\"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/files\/file_4379f50c-e237-48f9-beae-a4e625c5b304_icon.png?9736775303194905289\" alt=\"Download technical document - datasheet - Tanotis India\" width=\"25\"\u003e\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cbr\u003eAll product and company names are trademarks™ or registered® trademarks of their respective holders.
