LTC7821IUH#PBF Overview


The switching controller fits in the 32-WFQFN Exposed Pad package and is ideal for most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. PMIC packaging is solid with a Tube enclosure. There are Transistor Driver dc switching's output (s) that it can handle. dc control's supply and operating voltages are 10V~72V. Qualified to work in an dc switcher with -40°C~125°C TJ. There is a switch at 200kHz~1.5MHz that can be used with this controller. dc dc regulator can be generalized using Surface Mount. Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking provides dcdc regulator efficient switching control. An analog IC SWITCHING REGULATOR is connected to the switch converters. A switching converters's terminal (s) sits at the QUAD position. A variety of dc switching's functions can be performed on 32 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input of 48V. In addition to "LTC7821", there are other relevant dc to dc converter ics you can find. There are only 32 pins on switching converter. 33.5V is tested as the maximum voltage output of the dc controller.
