LTC3872EDDB-1#TRPBF Overview


The switching controller fits in the 8-WFDFN Exposed Pad package and is ideal for most applications. There is sufficient capacity to generate switching controller for outputs 1. A solid enclosure of Tape & Reel (TR) surrounds pmic. Transistor Driver dc switching's outputs (s) are supported. dc controls with 2.75V~9.8V voltage are supplied and operated. Worked in a -40°C~85°C TA dc switcher before. In this switching controller, the switch can be set to 550kHz. dc dc regulator is made easier with Surface Mount. To provide efficient switching control, Current Limit, Enable, Soft Start is included in the dcdc regulator. The switch converters are connected to a SWITCHING CONTROLLER analog IC. There are a DUAL terminal on the switching converters. A variety of terminations with 8 of dc switching. DC switcher's voltage input is 4.2V. You can find other relevant dc to dc converter ics by searching "LTC3872". Input voltage of dc dc voltage regulator must be 2.75V. It should be noted that the dc to dc regulator only accepts 9.8V voltage as input voltage.
