RT8540WSC Overview

To save board space, it uses the 20-UFBGA, WLCSP package. It has 3 outputs for LED drivers.As far as mounting is concerned, Surface Mount is adopted.With high efficiency, it emerges as a DC DC Regulator.It is possible for the led driver ic to function normally at -40°C~85°C TA.The benefits of LED Lighting are considerable.2MHz is the frequency in which it operates.Undetermined failures may occur when the voltage supply is less than 2.5V.The voltage at the output terminal is 2.5V~5.7V.This device is optimized to deliver a maximum voltage level of 5.5V.
