LM3643AYFFR Overview

The 12-UFBGA, DSBGA package is used for saving board space. A LED driver with 2 outputs is designed.Surface Mount represents this mounting method.With high reliability and efficiency, this emerges as a DC DC Regulator.The led light driver is capable of working normally at -40°C~85°C TA.There are considerable benefits for Camera Flash.A termination of 12 is used to operate the LED driver.Its configuration is based on 12 pins.It is estimated that there are 2 segments.There is a mounting of it by Surface Mount.LED drivers have a base part number of LM3643.There is no problem with the voltage of 5.5V.12 pins are used on the device.This device requires a minimum input voltage of 2.5V.The maximum supply current is 5.5V.This electronic component can fully perform its functions when the switching frequency is kept at 4MHz.Even when operating at a maximal output current of 1.5A, it is capable of delivering all the benefits of a LED driver.In the absence of external factors, there is 300μA consumption of current.
