LTC7801EFE#PBF Overview

The switching controller fits in the 24-TSSOP (0.173, 4.40mm Width) Exposed Pad package and is ideal for most applications. 1 outputs can be generated with the dc motor controller. The pmic is packaged in Tube solid enclosure. There are Transistor Driver dc switching's output (s) that it can handle. 4V~140V is the operating voltage and supply voltage of the dc control. Suitable for a -40°C~125°C TJ dc switcher. This switching controller can switch at 50kHz~900kHz. The Surface Mount allows it to be used for dc dc regulator in general. To ensure efficient switching, this dcdc regulator features a Current Limit, Power Good, Soft Start, Tracking. The switch converters are connected to a SWITCHING CONTROLLER analog IC. The switching converters's terminals (s) are designed at DUAL. 24 terminations with a variety of function. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. 12V nominal DC switcher's voltage input. LTC7801 can be used to locate other relevant dc to dc converter ics. Total pins of switching converter are 24. An input voltage of 4V is the minimum required for the dc dc voltage regulator. We test the dc controller's highest voltage output at 60V.
