LTC3808EDE Overview


With a 14-WFDFN Exposed Pad package, the switching controller is suitable for a wide range of applications. There is sufficient capacity to generate switching controller for outputs 1. With this function, you can deal with Transistor Driver dc switching's outputs (s). A 2.75V~9.8V voltage is supplied to the dc control and used for operating it. Worked in an dc switcher with a -40°C~85°C TA rating. In this switching controller, the switch can be set to 250kHz~750kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Power Good, Soft Start, Tracking. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . The 14 terminations can be used for a wide range of dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 4.2V. Searching "LTC3808" will return other relevant dc to dc converter ics. Specially, switching converter corresponds to type Switching Regulator or Controllers. It is recommended that the dc dc voltage regulator's minimum input voltage be 2.75V. Voltages 9.8V are the maximum that the dc to dc regulator will accept. In order to satisfy the need, DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.6V TO 9.8V. Switching converter outputs current to the greatest value of 1A.
