LT3955IUHE Overview
In order to save board space, the 36-WFQFN, 28 Leads, Exposed Pad package is used. In LED drivers, the outputs are all set to 1.As far as mounting is concerned, Surface Mount is adopted.Initially, it emerges as a DC DC Regulator with high efficiency and a high degree of reliability.-40°C~125°C TJ is the operating temperature for the led light driver.100kHz~1MHz is the frequency in which it operates.A termination of 28 is used to operate the LED driver.Failures may occur if the voltage supply is below 4.5V.The number of segments is estimated to be 12.There are 36 pins on it.A maximum voltage of 60V is optimized for use by this device.In addition, it can also be categorized into Display Drivers based on its characteristics.This LED driver belonging to the True Color PWM? series is a key component for a broad range of applications.
