LTC3872HDDB-1#TRPBF Overview
With its 8-WFDFN Exposed Pad package, the switching controller fits the needs of most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. PMIC is packaged in a solid enclosure of Tape & Reel (TR). There are Transistor Driver dc switching's output (s) that it can handle. A 2.75V~9.8V voltage is supplied to the dc control and used for operating it. Qualified to work in an dc switcher with -40°C~150°C TJ. In this switching controller, the switch can be set to 550kHz. Surface Mount makes it suitable for general dc dc regulator. Current Limit, Enable, Soft Start provides dcdc regulator efficient switching control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. A switching converters's terminal (s) sits at the DUAL position. Different dc switching's functions can be applied to 8 terminations. DC switcher's voltage input is 4.2V. LTC3872 can be searched for other relevant dc to dc converter ics. It is recommended that the input voltage of the dc dc voltage regulator be 2.75V. At most, the dc to dc regulator accepts 9.8V input voltage.
