LTC3789EGN#PBF Overview
Capsuled in the 28-SSOP (0.154, 3.90mm Width) package, the switching controller suits most application needs. 2 outputs are supported by the dc motor controller. Packaging for the pmic consists of Tube solid enclosures. A total of Transistor Driver dc switching's outputs can be handled by it. 4V~38V is the operating voltage and supply voltage of the dc control. A -40°C~125°C TJ dc switcher is not a problem. Using this switching controller, it is possible to switch at 200kHz~640kHz. dc dc regulator can be generalized using Surface Mount. Current Limit, Enable, Frequency Control, Power Good, Soft Start provides dcdc regulator efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. A switching converters's terminal (s) sits at the DUAL position. An array of 28 terminations of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. There is a DC switcher's nominal voltage of 15V. Searching "LTC3789" will return other relevant dc to dc converter ics. Specially, switching converter corresponds to type Switching Regulator or Controllers. It is recommended that the dc dc voltage regulator's minimum input voltage be 4V. Statistically, the DC regulator outputs 5.5V voltage. It should be fully noted that the dc to dc regulator only accepts 38V input voltage at most. For better satisfaction, the value of DC to DC voltage regulator is ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 38V.
