LTC3789IGN#PBF Overview


This switching controller fits most application requirements since it is packaged in a 28-SSOP (0.154, 3.90mm Width) package. This dc motor controller can be used to generate outputs with 2 numbers. Tube solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. DC control operates at 4V~38V volts and has 4V~38V supply voltage. A -40°C~125°C TJ dc switcher is not a problem. The switching controller is capable of switching at the 200kHz~640kHz position. dc dc regulators can be carried out with Surface Mount. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Power Good, Soft Start. SWITCHING CONTROLLER analog IC connects the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. An array of 28 terminations of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. In addition to "LTC3789", there are other relevant dc to dc converter ics you can find. In particular, switching converter belongs to the Switching Regulator or Controllers family. This dc dc voltage regulator should be powered by a voltage of 4V. Statistically, the DC regulator outputs 5.5V voltage. Voltages 38V are the maximum that the dc to dc regulator will accept. To better satisfy the need, DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 38V.
