LT3755EMSE-2 Integrated Circuit Chip 4.5V To 40V LED Controllers MSOP-16 Packge
Product Description Of LT3755EMSE-2
LT3755EMSE-2 is DC/DC controllers designed to operate as a constant-current source for driving high current LEDs. The drive 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.
