LINEAR TECHNOLOGY LT3755EMSE-2#PBF 发光二极管驱动器, 1输出, 升压, 降压, 降压-升压, 4.5V-40V输入, 1MHz开关, 75V/1A输出, MSOP-16
The is a LED Controller designed to operate as a constant-current source for driving high current LEDs. It drives a low side external N-channel power MOSFET from an internal regulated 7.15V supply. The fixed frequency, current mode architecture results in stable operation over a wide range of supply and output voltages. A ground referenced voltage FB pin serves as the input for several LED protection features and also makes it possible for the converter to operate as a constant-voltage source. A frequency adjust pin allows the user to program the frequency from 100kHz to 1MHz to optimize efficiency, performance or external component size. The LT3755-2 sense output current at the high side of the LED string. High side current sensing is the most flexible scheme for driving LEDs, allowing boost, buck mode or buck-boost mode configuration. The PWM input provides LED dimming ratios of up to 3000:1 and the CTRL input provides additional analogue dimming capability.
