LT3954EUHE Overview
Additionally, there is a 36-WFQFN, 28 Leads, Exposed Pad package for saving space.A LED driver using this design has 1 outputs.Surface Mount represents this mounting method.It emerges as a DC DC Regulator, which is efficient and reliable.If the led driver ic is set to -40°C~125°C TJ, it will work normally.As a result, it operates in accordance with the frequency of 100kHz~1MHz.In order for it to operate, it has 36 terminations.It is possible for undetermined failures to occur if the voltage supply is lower than 4.5V.In this device, there are 36 pins.The voltage range of this device is optimized for a maximum supply voltage of 40V.Several applications make use of this LED driver from the True Color PWM? series.There are 24V volts assigned to the circuit when operating the device.When the input voltage is greater than or equal to 4.5V, the operation of this device is greatly simplified.Aside from that, it has SEATED HT-CALCULATED as a characteristic.The input voltage should be kept below 40V to ensure high stability.
