description

LT®3755、LT3755-1andLT3755-2beDC/DCThe controller is designed to act as one for driving high currentsLEDThe constant current source is designed. They have been tuned from an inside7.15VThe power supply to drive a lowendexteriorNChannel powerMOSFET。 The fixed-frequency, current-mode architecture enables stable operation over a wide range of supply and output voltages. A voltage referenced to groundFBPins are used as multipleLEDProtects the input of the functional circuit and also allows the converter to act as a constant voltage source. A frequency adjustment pin allows the user to operate in 100kHzreach1MHzto set frequencies to optimize efficiency, performance, or external component size.

LT3755/LT3755-1/LT3755-2atLEDThe high side of the string senses the output current. High-side current sensing is used for drivingLEDThe most flexible solution, allowing boost, buck mode, or buck-Boost mode configuration.PWMInput provides up to3000:1targetLEDDimming ratio, whileCTRLThe inputs provide additional analog dimming capabilities.
