LM27952SD Overview
14-WFDFN Exposed Pad saves board space. Typically, LED drivers have 4 outputs.In this case, mounting method is Surface Mount.When it emerges as a DC DC Regulator, it performs extremely well and is highly reliable.The led light driver operates normally at -40°C~85°C TA. As a result, Backlight is likely to benefit greatly.A frequency of 750kHz is used as the basis for operation.It operates with 14 terminations.Undetermined failures can occur if the voltage supply is below 3V.The segment count is 4.LM27952 is the base part number for this LED driver.The voltage at the output terminal is 2.5V~3.9V.On it, there are 14 pins.It supports a maximum value of 5.5V.Additionally, it is categorized into Display Drivers according to its characteristics.
