description

LT®3755、LT3755-1andLT3755-2beDC/DCThe controller is designed to act as a driving high currentLEDconstant current source. They are tuned from one inside7.15VPower 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 that refers to the 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 regulation pin allows the user to be in100kHzreach1MHzSet frequencies to optimize efficiency, performance, or external component size.
