LM27964SQ-I/NOPB Product Details
LM27964SQ-I/NOPB Overview
As a result of its 24-WFQFN Exposed Pad package, it helps to save board space on the board. LED drivers design with 7 outputs.We are using Surface Mount as the mounting method.It is highly reliable and high-performing when it emerges as a DC DC Regulator.The led light driver operates normally at -30°C~85°C TA. Backlight benefits significantly from the program.It operates with terminations of 24.This LED driver is configured with a base of 24 pins.It is likely that undetermined failures will occur if the voltage supply is less than 2.7V.It is estimated that there are 22 segments.There is a mounting of it by Surface Mount.You can find this LED driver under the base part number LM27964.A maximum supply voltage of 5.5V is acceptable.The voltage at the output terminal is 2V~4V.Moreover, it can be classified as Display Drivers due to its characteristics.It is designed to operate at a minimal voltage of 2.7V to achieve the highest efficiency.When the maximum supply current is below 1.3mA, it is capable of delivering high efficiency.You can supply 180mA current to the load.This electronic component can fully perform its functions when the switching frequency is kept at 700kHz.Absent external factors, there is 1.3mA consumption of current.
