LTC3859ALIFE#PBF Overview

This switching controller fits most application requirements since it is packaged in a 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package. There is sufficient capacity to generate switching controller for outputs 3. Tube is the solid enclosure in which PMIC is packaged. Transistor Driver dc switching's outputs (s) are supported. 4.5V~38V is the supply voltage and the operating voltage of the dc control. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. In this switching controller, the switch can be set to 115kHz~835kHz 350kHz~535kHz. The Surface Mount value 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. An analog IC SWITCHING CONTROLLER is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . The 38 terminations can be used for a wide range of dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. It is inputted with a DC switcher's voltage of 12V. LTC3859 can be searched for other relevant dc to dc converter ics. The type is a particular Switching Regulator or Controllers of switching converter. The minimum input voltage of the dc dc voltage regulator should be 4.5V.
