Led Driver Ic 350ma


Certain demo boards are also available for sale via credit card on this website. It contains a 100m Ohm NFET switch and a 130m Ohm PFET synchronous rectifier. The LTC3490 limits the output voltage to 4.7V if the output load is disconnected. Solder plated terminal finish (SnPb) versions are non-standard and special terms and conditions and pricing applies if available. http://vinaprosoft.com/led-driver/led-driver-24v-350ma.php

It remains the customer’s responsibility to verify proper and reliable operation in the actual end application. Features Wide 4.5 V to 42 V input voltage range Internal power switch Overcurrent protection Overvoltage protection Reversible temperature shutdown mechanism Inherent open circuit LED protection Soft-start capability Low shut down An undervoltage lockout circuit shuts down the LTC3490 when the battery voltage drops below 0.85V/cell. A low-battery logic output signals when the battery has dropped below 1V/cell.
