LT3743IFE#PBF Overview


28-TSSOP (0.173, 4.40mm Width) Exposed Pad saves board space. LED drivers designed using this technology use 1 outputs.The mounting method is Surface Mount.When it emerges as a DC DC Controller, it performs extremely well and is highly reliable.This LED driver can be operated at a temperature of -40°C~125°C TJ. A number of benefits are available to Lighting.Based on the frequency of 200kHz~1MHz, it operates on the basis of a pulse.28 terminations are used in its operation.This module has 28 pins as its base.The LED driver can be found under the base part number LT3743.36V is a reasonable voltage.The device has 28 pins.At a voltage of 6V, it operates at a minimal input voltage.A minimal supply voltage of 6V is required for it to achieve the highest efficiency.The maximum supply current is reached when 36V is reached.A load can be supplied with 20A current.When the switching frequency is maintained at 1MHz, this electronic component is able to fully play its functions.There is 40V voltage output from it.The circuit is assigned 12V volts when the device is in operation.Aside from that, it has ALSO OPERATES IN ADJUSTABLE MODE FROM 0V TO 34V as a characteristic.
