SC2446ITSTRT Product Details
SC2446ITSTRT Overview
With its 28-TSSOP (0.173, 4.40mm Width) package, the switching controller fits the needs of most applications. For outputs of 2, this dc motor controller is suitable. Tape & Reel (TR) solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 4.7V~16V and has a 4.7V~16V supply voltage. Worked in a -40°C~85°C TA dc switcher before. In this switching controller, the switch can be set to 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Enable, Frequency Control, Soft Start. DUAL SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . The 28 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. Searching "SC2446" will return other relevant dc to dc converter ics. 28 pins are on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. Input voltage of dc dc voltage regulator should be 4.7V. It should be noted that the dc to dc regulator only accepts 16V voltage as input voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 3A. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 88 %.
