LM2754SQ Overview
To save board space, it uses the 24-WFQFN Exposed Pad package. The LED driver's design uses 4 outputs.As far as mounting is concerned, Surface Mount is adopted.This emerges as a DC DC Regulator with high efficiency and reliability.It is capable of working normally at -40°C~85°C TA.Taking advantage of Camera Flash has considerable benefits.In this case, the termination value is 24.It has a base of 24 pins.A total of 4 segments are estimated.On the Surface Mount, a device is mounted.It is under the base part number LM2754 that you can find this LED driver.The supply voltage of 5.5V is an acceptable maximum value.The output voltage of this device is 4.7V~5.1V.24 pins are used on the device.Furthermore, it can be classified as Display Drivers based on its characteristics.It operates with the minimal input voltage of 2.8V.This system is designed to operate at a minimum voltage of 2.8V to achieve maximum efficiency.In terms of supply current, 5.5V is the maximum value.This device is able to provide high efficiency when the maximal supply current should be less than 8mA.It is possible to supply the load with 800mA current.The electronic component can fully perform its functions if the switching frequency is maintained at 1MHz.When no external factors are present, there is 3.4mA current consumption.There shouldn't be an increase in output voltage over 5.1V.
