LTC3789IGN#TRPBF Overview

In the 28-SSOP (0.154, 3.90mm Width) package, the switching controller meets most application requirements. It is sufficient to generate 2 outputs with this dc motor controller. PMIC is packaged in a solid enclosure of Tape & Reel (TR). There are Transistor Driver dc switching's output (s) that it can handle. This dc control has a supply voltage and operating voltage of 4V~38V. 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 200kHz~640kHz. A generalization of dc dc regulator can be made using Surface Mount. The dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start for efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. The 28 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. A search for "LTC3789" will reveal other relevant dc to dc converter ics. Pins number 28 of switching converter in total. Particularly, switching converter is a type of Switching Regulator or Controllers. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. Statistically, DC regulator outputs 38V volts. The dc dc regulator's usual output current is 20A, which should be noted down when you start a project. There is a maximum frequency of 710kHz for this dc regulators. To better satisfy the need, DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 38V.
