LTC3859ALHFE Overview

The switching controller fits in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package and is ideal for most applications. For 3 outputs, the dc motor controller is appropriate. An enclosure of Tube is used to package the PMIC. Transistor Driver dc switching's outputs (s) can be handled by it. Voltages 4.5V~38V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in a -40°C~150°C TJ dc switcher. Switching can be done at 115kHz~835kHz 350kHz~535kHz with this switching controller. A generalization of dc dc regulator can be made using Surface Mount. The dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking for efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Thare switching converters has a terminal (s) at DUAL . 38 terminations with a variety of function. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. Search for "LTC3859" to find other relevant dc to dc converter ics. Specially, switching converter corresponds to type Switching Regulator or Controllers. Input voltage of dc dc voltage regulator must be 4.5V.
