LTC1873EG#PBF Overview


Capsuled in the 28-SSOP (0.209, 5.30mm Width) package, the switching controller suits most application needs. For outputs of 2, this dc motor controller is suitable. The pmic is packaged in Tube solid enclosure. The system can process Transistor Driver dc switching's outputs (s). DC control operates at 3V~7V volts and has 3V~7V supply voltage. Suitable for working in an dc switcher that has a -40°C~85°C TA. A generalization of dc dc regulator can be made using Surface Mount. In order to control switching efficiently, the dcdc regulator features Enable, Soft Start. The switch converters are connected to a SWITCHING CONTROLLER analog IC. A switching converters's terminal (s) sits at the DUAL position. Various 28 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 5V. A search for "LTC1873" will reveal other relevant dc to dc converter ics. The switching converter has a total of 28 pins. DC regulator outputs 3.5V voltage based on test statistics. You should note down the dc dc regulator's usual output current of 25A when you start a project. 550kHz is the frequency of the switching controller. The dc switcher's maximum input voltage is 7V; users must limit it accordingly. Input current cannot exceed 5A with this dc switcher. The switching converter can output 3.5V volts at its utmost, according to the datasheet. For high-quality communication, there are 1 channels.
