LTC3809EMSE-1#PBF Product Details
LTC3809EMSE-1#PBF Overview
Capsuled in the 10-TFSOP, 10-MSOP (0.118, 3.00mm Width) Exposed Pad package, the switching controller suits most application needs. It is sufficient to generate 1 outputs with this dc motor controller. A solid enclosure of Tube surrounds pmic. It is capable of handling Transistor Driver dc switching's outputs (s). DC control operates at 2.75V~9.8V volts and has 2.75V~9.8V supply voltage. Worked in an dc switcher with a -40°C~85°C TA rating. The switching controller can be switched at 550kHz. Surface Mount makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Enable, Soft Start, Tracking which allows efficient switching control. 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 10 terminations. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis set to 4.2V. LTC3809 can be used to locate other relevant dc to dc converter ics. The switching converter has a total of 10 pins. There is a particular type of Switching Regulator or Controllers in switching converter. This dc dc voltage regulator should be powered by a voltage of 2.75V. Statistically, DC regulator outputs 9.8V volts. You should note down the dc dc regulator's usual output current of 1A when you start a project. 750kHz is the frequency of the switching controller.
