LT3477EFE#PBF Product Details
LT3477EFE#PBF Overview
There is a 20-TSSOP (0.173, 4.40mm Width) Exposed Pad package on the board that is used to save space. In this LED driver, there are 1 outputs.Surface Mount is used for mounting the led light driver.It emerges as a DC DC Regulator, which is efficient and reliable.It is possible for the led driver ic to function normally at -40°C~85°C TA.A frequency of 200kHz~3.5MHz is used to operate it.In order for it to operate, it has 20 terminations.Failures may occur if the voltage supply is below 2.5V.Part number LT3477 represents this LED driver.A total of 20 pins are present on this device.An optimized supply voltage of 25V is provided.According to its characteristics, it is also categorized into Switching Regulator or Controllers.While operating the device, the circuit has 2.5V volts.It is greatly simplified when used with input voltages greater than or equal to 2.5V.Keeping the input voltage below 0 ensures high stability.You should not exceed 5A for the output current.
LT3477EFE#PBF Features
Available in the 20-TSSOP (0.173, 4.40mm Width) Exposed Pad package Operating temperature of -40°C~85°C TA Frequency of 200kHz~3.5MHz
