LTC3859IFE Overview

The switching controller fits in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package and is ideal for most applications. This dc motor controller can be used to generate outputs with 3 numbers. Packaged in solid enclosures, this pmic has a Tube rating. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc controls with 4.5V~38V voltage are supplied and operated. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. A switching controller such as this can switch at a value of 115kHz~835kHz 350kHz~535kHz . Surface Mount makes it suitable for general dc dc regulator. To provide efficient switching control, Enable, Frequency Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. 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. Different dc switching's functions can be applied to 38 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 12V. LTC3859 can be used to locate other relevant dc to dc converter ics. Switching converter is a type of Switching Regulator or Controllers in particular. An input voltage of 4.5V is the minimum required for the dc dc voltage regulator. Statistically, DC regulator outputs 5.4V volts.
