LT1681ESW#PBF Overview

Capsuled in the 20-SOIC (0.295, 7.50mm Width) package, the switching controller suits most application needs. PMIC packaging is solid with a Tube enclosure. Suitable for work in a -40°C~85°C dc switcher. It is suitable for general dc dc regulator when it is set to Surface Mount. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . Different dc switching's functions can be applied to 20 terminations. DC switcher's input voltageis set to 12V. In addition to "LT1681", there are other relevant dc to dc converter ics you can find. In particular, switching converter belongs to the Switching Regulator or Controllers family. 9V should be the minimum input voltage for the dc dc voltage regulator. At most, the dc to dc regulator accepts 18V input voltage. A total of 1 functions are present in the switch converters. It is planned to design voltage regulators switchings with 20 pins. It is possible for this switching controller to switch at a frequency of 700kHz.
