LTC7821EUH#TRPBF Overview
Capsuled in the 32-WFQFN Exposed Pad package, the switching controller suits most application needs. There is sufficient capacity to generate switching controller for outputs 1. Tape & Reel (TR) solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. dc control's supply and operating voltages are 10V~72V. Suitable for work in a -40°C~125°C TJ dc switcher. Using this switching controller, it is possible to switch at 200kHz~1.5MHz. dc dc regulator can be generalized using Surface Mount. To provide efficient switching control, Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING REGULATOR. There are a terminal (s) on the switching converters that are designed at QUAD. A variety of terminations with 32 of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 48V. Other relevant dc to dc converter ics will be returned if you search "LTC7821". Total pins of switching converter are 32. At 33.5V, the dc controller's highest voltage output is tested.
