It accepts an input voltage from 4.7V to 60V, and drives up to 25V of LEDs at 2A. DC1666A features both PWM and analogue dimming of the LED string. It has an OPENLED flag that indicates when the LED string has been removed and it has a SHORTLED flag that indicates that the output has been shorted to GND. In both cases, the IC remains in control and well protected. DC1666A features very high efficiency at 300KHz switching frequency and continuous conduction mode (CCM). The synchronous four-switch topology both steps up and steps down voltage while regulating up to 50W of constant LED output current at efficiencies up to 98%. The circuit can be altered for applications requiring over 100W of LEDs. An optional SYNC terminal is provided for synchronizing to an external clock and CLKOUT terminal provides a source to sync another converter to the internal clock of the LT®3791.\u003c\/p\u003e\n  \u003cul\u003e\n   \u003cli\u003e2.0A ILED current (CTRL = Float, 7V \u0026lt; PVIN \u0026lt; 57.6V)\u003c\/li\u003e\n   \u003cli\u003e9.5V \u0026lt; VLED \u0026lt; 25.5V VLED range (R7 = 1M, R9 = 44.2k)\u003c\/li\u003e\n   \u003cli\u003e28.3V open LED voltage (R7 = 1M, R9 = 44.2k)\u003c\/li\u003e\n   \u003cli\u003e11A peak switch current limit boost region (RS = 0.004ohm)\u003c\/li\u003e\n   \u003cli\u003e10A valley switch current limit buck region (RS = 0.004ohm)\u003c\/li\u003e\n   \u003cli\u003eSimple PWM dimming\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\u003eSynchronous Buck-Boost\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eOutput Current\u003c\/span\u003e\n     \u003cp\u003e2A\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eInput Voltage Min\u003c\/span\u003e\n     \u003cp\u003e4.7V\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eCore Chip\u003c\/span\u003e\n     \u003cp\u003eLT3791EFE\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eKit Contents\u003c\/span\u003e\n     \u003cp\u003e0\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\u003e25.5V\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eInput Voltage Max\u003c\/span\u003e\n     \u003cp\u003e60V\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\u003eDC1666A\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=\"https:\/\/www.analog.com\/media\/en\/technical-documentation\/user-guides\/dc1666af.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.
