SC2446ITSTRT Overview


It comes in a 28-TSSOP (0.173, 4.40mm Width) package, so switching controller can be used for most applications. 2 outputs are supported by the dc motor controller. The pmic is packaged in Tape & Reel (TR) solid enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 4.7V~16V are the dc control's supply voltage and operating voltage, respectively. A -40°C~85°C TA dc switcher is not a problem. In this switching controller, the switch can be set to 500kHz. dc dc regulators can be carried out with Surface Mount. The dcdc regulator features Enable, Frequency Control, Soft Start for efficient switching control. A DUAL SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. 28 terminations with various dc switching's functions. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's voltage input of 12V. A search for "SC2446" will reveal other relevant dc to dc converter ics. There are a total of 28 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. Input voltage of dc dc voltage regulator must be 4.7V. It should be fully noted that the dc to dc regulator only accepts 16V input voltage at most. In most cases, the dc dc regulator's output current is 3A. This information should be noted when you begin working with the component. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 88 % during power-up and power-down.
