LT3477IFE#TRPBF Overview


20-TSSOP (0.173, 4.40mm Width) Exposed Pad package saves space on the board. Typically, LED drivers have 1 outputs.As a mounting method, Surface Mount is used.When it emerges as a DC DC Regulator, it shows high-performance and reliability.-40°C~125°C TA is the operating temperature for the led light driver.Using the frequency of 200kHz~3.5MHz, it operates.The system operates with a termination of 0.The voltage supply can fail if it is below 2.5V.LED drivers can be found under the base part number LT3477.In this device, there are 20 pins.There is an optimization that allows a maximum supply voltage of 25V.As a result, its characteristics can also be categorized as Switching Regulator or Controllers.The circuit is assigned 2.5V volts when the device is in operation.Input voltages higher than or equal to 2.5V make its operation much more convenient.By keeping the input voltage below 25V, high stability can be achieved.The input voltage should be kept below 5A to ensure high stability.
