LTC1439EG#PBF Overview


The switching controller fits in the 36-SSOP (0.209, 5.30mm Width) package and is ideal for most applications. For outputs of 2, this dc motor controller is suitable. An enclosure of Tube is used to package the PMIC. There are Transistor Driver dc switching's output (s) that it can handle. 3.5V~30V is the supply voltage and the operating voltage of the dc control. Suitable for a -40°C~85°C TA dc switcher. The switching controller is capable of switching at the Up to 400kHz position. As it has a Surface Mount value, it can be used for general dc dc regulator. Enable, Power on Reset, Soft Start is used for efficient switching control in the dcdc regulator. DUAL SWITCHING CONTROLLER analog IC connects the switch converters. DUAL are the position of the terminal of the switching converters. 36 terminations with various dc switching's functions. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. Searching "LTC1439" will return other relevant dc to dc converter ics. Specially, switching converter corresponds to type Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 3.5V. The dc to dc regulator can only accept 36V input voltage. The output value is set to the greatest value of 2A.
