RT8474AGSP Overview
In order to save board space, the 8-SOIC (0.154, 3.90mm Width) Exposed Pad package is used. This LED driver has 1 outputs.For mounting, it uses the Surface Mount method.With high efficiency and reliable performance, it emerges as a DC DC Regulator.The LED driver is capable of operating at a temperature of -40°C~85°C TA.Backlight has significant advantages.It operates at 500kHz frequency.A voltage supply less than 4.5V will cause undetermined failures.It's mounted by Surface Mount.It is acceptable for the supply voltage to be 50V.There is 50V voltage output from the device.This value is designed to support a maximum of 50V.This device requires a minimum voltage of 4.5V volts.In the event that the maximum supply current is allowed, it reaches 50V.It is important not to exceed 85°C in order to ensure stable operation.Stable operation requires an operating temperature greater than -40°C.Having the switching frequency at 500kHz enables this electronic component to perform at its best.
