                                                LYT7503D Overview
There is also a 8-SOIC (0.154, 3.90mm Width) package that is used to save space on the board. LED drivers use 1 outputs for their design.The led driver mounting is done by using Surface Mount.When it emerges as a AC DC Offline Switcher, it shows high-performance and reliability.The LED driver has the capability of operating at a temperature of -40°C~150°C TJ.To form its configuration, 8 pins are used.A voltage supply less than 90VAC could result in undetermined failures.Optimally, it provides a voltage value of 308VAC for the maximum supply voltage.The electronic component can fully perform its functions if the switching frequency is maintained at 20kHz.LED drivers belonging to the series LYTSwitch?-7 are important components in a wide range of applications.The voltage at the output terminal is 60V.
