LTC3809EMSE#TRPBF Product Details
LTC3809EMSE#TRPBF Overview
The switching controller fits in the 10-TFSOP, 10-MSOP (0.118, 3.00mm Width) Exposed Pad package and is ideal for most applications. dc motor controller is suitable for 1 output generation. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. 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. Suitable for work in a -40°C~85°C TA dc switcher. With this switching controller, you can switch at 460kHz~635kHz. The Surface Mount makes it ideal for general dc dc regulator. Featured in the dcdc regulator is Enable which allows efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. There are a terminal (s) on the switching converters that are designed at DUAL. 10 terminations with various dc switching's functions. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 4.2V. Other relevant dc to dc converter ics will be returned if you search "LTC3809". Total pins of switching converter are 10. Particularly, switching converter is a type of Switching Regulator or Controllers. It is recommended to use 2.75V as the minimum input voltage of dc dc voltage regulator. Considering the dc to dc regulator can only accept 9.8V input voltage, it is important to take note of this. There is a maximum frequency of 825kHz for this dc regulators. Whenever the current value is 1A, switching converter outputs the highest possible value.
