LTC7821IUH#TRPBF Overview
It comes in a 32-WFQFN Exposed Pad package, so switching controller can be used for most applications. It is sufficient to generate 1 outputs with this dc motor controller. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 10V~72V and has a 10V~72V supply voltage. Suitable for work in a -40°C~125°C TJ dc switcher. This switching controller can switch at 200kHz~1.5MHz. dc dc regulators can be carried out with Surface Mount. Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. A SWITCHING REGULATOR analog IC is connected to the switch converters. QUAD are the position of the terminal of the switching converters. There are many different types of terminations for 32. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 48V. In addition to "LTC7821", there are other relevant dc to dc converter ics you can find. Total pins of switching converter are 32. A dc controller's highest output voltage is measured at 33.5V.
