LTC7821EUH#PBF Product Details

LTC7821EUH#PBF Overview


With a 32-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. dc motor controller is suitable for 1 output generation. Packaging for the pmic consists of Tube solid enclosures. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThe supply and operating voltage of the dc control are 10V~72V. Work well in dc switchers with a -40°C~125°C TJ. It can switch at 200kHz~1.5MHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking which allows efficient switching control. The switch converters are connected to an analog IC with a SWITCHING REGULATOR output. A switching converters's terminal (s) sits at the QUAD position. An array of 32 terminations of dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 48V. Search for "LTC7821" to find other relevant dc to dc converter ics. Pins number 32 of switching converter in total. At 33.5V, the dc controller's highest voltage output is tested.
