description

LT®3756、LT3756-1andLT3756-2beDC/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. One reference to the voltage to groundFBPins are used as multipleLEDProtects the input of the functional circuit and also enables 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.
