LM3431MHX/NOPB Overview
28-PowerTSSOP (0.173, 4.40mm Width) package saves space on the board. Typically, LED drivers have 3 outputs.Surface Mount represents this mounting method.With high efficiency, it appears as a DC DC Controller.When the temperature is -40°C~125°C TJ, it can work normally.Taking advantage of Backlight has considerable benefits.A configuration of this chip is made up of 28 pins.Undetermined failures may occur when the voltage supply is less than 4.5V.It's mounted in Surface Mount.Part number LM3431 represents this LED driver.Ideally, the supply voltage should be 36V.The maximum efficiency standards can be met by operating at the minimal voltage of 4.5V during operation.Electronic components can function properly when their switching frequency is set to 1MHz.Absent external factors, there is 4mA consumption of current.Output current should not exceed 0.7A.
LM3431MHX/NOPB Features
Available in the 28-PowerTSSOP (0.173, 4.40mm Width) package
Operating temperature of -40°C~125°C TJ
Switching frequency of 1MHz
