LM2791LD-L Overview
The 10-WFDFN Exposed Pad package saves space on the board. LED drivers have a total of 2 outputs that are used in the design of the drivers.We are using Surface Mount as the mounting method.When it emerges as a DC DC Regulator, it shows high-performance and reliability.-30°C~85°C TA is a valid operating temperature for the led driver.Backlight benefits significantly from the program.Based on the frequency of 650kHz, it operates on the basis of a pulse.For its operation, terminations with a value of 0 are used.A configuration of this chip is made up of 10 pins.There may be undetermined failures if the voltage supply falls below 3V.2 segments are present.It's mounted by Surface Mount.LM2791 is the base part number for the LED driver.A maximum supply voltage of 5.8V is acceptable.A total of 10 pins are present on this device.It is also classified into Display Drivers according to its characteristics.As a result, it runs at a minimal voltage of 3V in order to achieve the best efficiency.As long as the maximum supply current is less than 2mA, this device is capable of providing high efficiency.The electronic component can fully perform its functions if the switching frequency is maintained at 450kHz.In the absence of external factors, 700μA current is consumed.
