SC493ULTRT Overview


As a result of 20-UFQFN Exposed Pad compact design, the switching controller is compatible with most applications. The dc motor controller is adquate to generate for 1 outputs. The pmic is packaged in Tape & Reel (TR) solid enclosure. With this function, you can deal with Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 3V~5.5V. Workable in an dc switcher where -40°C~85°C TA is the -40°C~85°C TArm. It can switch at 250kHz~1MHz. Surface Mount makes it suitable for general dc dc regulator. Current Limit, Enable, Power Good is used for efficient switching control in the dcdc regulator. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. Switching converters are designed with the terminal (s) at position QUAD . A variety of terminations with 20 of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input of 5V. The type is a particular Switching Regulator or Controllers of switching converter. dc dc voltage regulators should have a minimum input voltage of 3V. Statistically, the DC regulator outputs 3.3V voltage. A maximum voltage of 28V is accepted by the dc to dc regulator as an input voltage. The dc dc regulator's usual output current is 8.3A, which should be noted down when you start a project. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. For better satisfaction, the value of DC to DC voltage regulator is ALSO OPERATES IN ADJUSTABLE MODE FROM 0.5 TO 5V. If the user wishes to run the voltage regulator dc to dc in a circuit safely and reliably, they should apply 5.5V. It belongs to the EcoSpeed?, SmartDrive? series of dc to dc voltage regulator.
