AL3157F-7 Overview
Save board space with 12-UFDFN Exposed Pad package. As part of the design of this LED driver, there are 4 outputs that have been used.Mounting is done according to the Surface Mount method.When it emerges as a DC DC Regulator, it shows high-performance and reliability.The led light driver can work at -40°C~85°C TA.There are considerable benefits for Backlight.It operates based on the frequency of 1.2MHz.12 terminations are designed for its operation.This configuration is built upon 12 pins.In the absence of a voltage supply of at least 2.7V, undetermined failures may occur.I have mounted it by Surface Mount.An acceptable maximum value for the supply voltage is 5.5V.12 pins are available on the device.As a result, it is designed to operate at a minimal voltage of 2.7V to ensure the most efficiency possible.Loads can only be powered by 300mA current.This device produces a voltage of 11V as its output.
